• How to avoid Windows Genuine Advantage for an XP update?

  - by hlovdal

  I am about to apply updates to a windows xp installation I have not booted in a couple of years. When going to update.microsoft.com, it forced me first to accept an activex installation and now it wants me to install wga: Windows Update To use this latest version of Windows Update, you will need to upgrade some of its components. This version provides you with the following enhancements to our service: <... useless list of "advantages" ...

• Why does ATI 5570 HD video card driver installation cause Windows 7 To Blue Screen?

  - by Mort

  This one is for the hive mind. I have a brand new Dell Optiplex 760 workstation with 4 gigabytes of RAM running Windows 7 Professional (32bit). This is a new box with nothing installed other than what was provided for directly by Dell. I installed a Saphire ATI PCI Express 5570 HD. Upon trying to install the 10.4 Catalyst drivers the system will blue screen. It blue screens during the hardware detection phase of the installation process. I have already performed the following trouble shooting steps: Changed system RAM Installed only 2 gigabytes of RAM Installed different versions of Catalyst drivers (10.4 - 9.12) Tried to install video only component of driver (vs entire Catalyst suite) Made sure Windows 7 was fully updated Flashed mother board BIOS to current version Removed and re-seated video card Contacted ATI Support (We all know how this went......) Verified supply outputting properly The blue screen error (via Windows BugCheck entry in event log) is a 0x000000CA and refers to a plug and play error most likely caused by a bad driver. The problem is that the driver installation process never gets far enough to actually install a driver. The resolution center in Windows provides a solution of installing the 10.4 Catalyst driver to resolve issue (which fails). Looking for some alternate views to resolve.

• Fedora 9 not reconizing hard drive

  - by Andrew Jones

  I am installing Fedora 9 to a PC (specifications at the bottom) and have had a lot of trouble with it recognising the hard drive. To get the Fedora installer to recognize it in the first place I had to pass "ata_generic.all_generic_ide=1 pci=nomsi" to the kernel, after which it installed OK. However, now when I boot the installed OS, I get a "could not find filesystem '/dev/root'" error. I tried passing the same arguments to the kernel at boot as I did when installing but to no avail. I have tried using the default LVM layout and defining manual ones but it made no difference. There is no option in the BIOS to enable AHCI or anything like that, in fact the BIOS is very limited in most respects. I can get into the system by using the installation CD in rescue mode (with those extra kernal parameters) but I'm not sure what to do once in there... Unfortunately using a more recent version of Fedora or even another Linux distribution altogether isn't an option becuase of outside constraints - which is annoying since I know for a fact Ubuntu works fine on this setup. I have not been using Linux that long, so treat me like an idiot - I am one. Any help would be greatly appreciated, thanks!

• Dual booting Linux/Win7, Grub refuses to load Win7

  - by JohnB

  Decided to give Linux Mint a try (Ubuntu's interface annoys me), so I installed it with the intention of dual booting with Windows 7. Installation went fine, but now I can only boot into Linux Mint. Grub lists two Windows 7 menu options, but selecting either of them causes an "unknown file system" error and dumps me into a Grub recovery prompt. There, I have to manually reset the root and prefix options, as they reset hd0,msdos6 when they should be hd0,msdos5. I ran Boot Repair twice, once to fix grub errors, once to rebuild the MBR, but it didn't fix anything. Here is the log: http://paste.ubuntu.com/1029675/ fdisk output: Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 1486249145 743021149 7 HPFS/NTFS/exFAT /dev/sda3 1486249982 1953523711 233636865 5 Extended /dev/sda5 1486249984 1945141247 229445632 83 Linux /dev/sda6 1945143296 1953523711 4190208 82 Linux swap / Solaris grub.cfg: ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os { insmod part_msdos insmod ntfs set root='(hd0,msdos1)' search --no-floppy --fs-uuid --set=root 86184D18184D091F chainloader +1 } menuentry "Windows 7 (loader) (on /dev/sda2)" --class windows --class os { insmod part_msdos insmod ntfs set root='(hd0,msdos2)' search --no-floppy --fs-uuid --set=root 56D84F84D84F60FB chainloader +1 } ### END /etc/grub.d/30_os-prober ### I have found a few similar troubleshooting guides so far, but so far no amount of updating/configuring Grub has been successful.

• Officially announced RAM support size doesn't apply to one of twin rigs with just one difference

  - by Deniz

  It'll take a little long to describe my situation but here goes the story : In January 2009 we bought (the OEM parts) two similar systems with just one difference. One of them had a Phenom X4 cpu and the other one (mine) a Phenom X3 cpu. At the beginning we had problems with both systems to power them on whilst having all of their ram slots being full. We decided to install the systems with just 2 slots populated and later try to install the rest of ram sticks. Both systems did succeed to support 3 sticks. We tried many different procedures to make the systems work with their fourth ram slots being populated. We waited for new bios updates and flashed the boards when they were available, we tried different ram sticks with different frequencies etc. One day while we were trying to install the fourth stick, the X4 machine did accept it. The other one did not. The most mind boggling thing was that after one of my trials the X3 system begun to not operate with the third slot populated. Our boards did have AMD 770 chipsets and we even tried to change the board of the X3 machine with another 770 chipset board. Now my questions are : Should we change the cpu ? What is causing the X3 system to not accept the fourth (or now the third) ram stick ? The manufacturers sites do claim that this boards do accept 4 ram sticks (but they only tested them with certain ram brands and models). What are the limitations for maximum ram configurations on motherboards ? Are there some "rules of thumb" except frequency, voltage, chip type considerations for which we did check our parts ? Our boards are : Gigabyte GA-MA770-DS3 Sapphire PC-AM2RX780 - PURE CrossFireX 770

• If I can take a screen capture of a graphical anomaly, can it still be a hardware issue?

  - by Jay Carr

  I have a strange graphical anomaly going on my iMac right now (green and magenta boxes are appearing sporadically), I'm slowly trying to work through different possibilities but I thought I'd start with the basics: Can a graphical anomaly that I can screen capture still be a hardware issue? I know, it seems really obvious. If it's hardware, it should show up well after the operating system has had it's say. And since the operating system is (I assume) doing the screen capture, it seems like it shouldn't see the anomaly unless the problem is software in nature. But, as I've researched this problem I see a lot of people taking their computers in to service people for hardware issues and Apple then resolving said issue. To further complicate things, I also have Windows 8 installed via bootcamp, and the issues seems to be showing up there as well. Anyway, it feels like it must be a driver issue, since I assume that's what the two OSes have in common, but...I thought I'd come here for some disambiguation. In my case, yes, I can screen capture the anomaly (at least in OSX I can), so I assume it's somehow a software (or driver) issue. But I wanted to double check because the internet is being ambiguous...

• How can a Postfix/Dovecot(ssl)/Apache/Roundcube(non-ssl) setup leak email addresses?

  - by Jens Björnhager

  I have a linux box email server with Postfix as the MTA, Dovecot as the IMAP server and Apache with Roundcube as webmail. In my /etc/postfix/aliases I have just above a hundred different aliases which makes as many email addresses on my domain. I use one address per website so I easily can shut down spam infested addresses. During the half a year or so that I have had this setup, I have received 3 spam from 2 sources. As I know exactly where I entered this address, it should be easy to pinpoint email leaking websites and services. However, these sources are, according to me, not likely email sellers. And for one of them to sell my email twice? I contacted one of the sources and they are adamant that their system is tight. They suggested the possibility that it is my server that is doing the leaking. So, my question is: How likely is it that my box is leaking email addresses, and how? I don't store fully qualified email addresses anywhere in my system except in my maildir. I use SSL connection to IMAP I do not use https on webmail

• How to deal with lots of brackets in a formula?

  - by wenlibin02

  Say, I have a formula like this (in LaTeX or Maple or other text system): Result: ((6*(k2+k3))*A123*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2+6*A12*(-k3+k2)*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*(exp(-k2*(k2^2*t-x)))^2+(-(6*(-k3+k2))*A13*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2-(6*(k2+k3))*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*exp(-k2*(k2^2*t-x)) Note: the above formula is only one part of the result of a maple calculation, I just can't break them up because there are so many many terms. Apparently, It's very hard to read. What I want to do is to fold the matched brackets level by level. If all the brackets are folded, I can find out clearly how many terms there are. Then I can analyze from the top level to the details of every term. But I just don't know how to realize that. Maybe there are some existed software which can visualize this kind of complex formula. Any idea? P.S. I use Linux system. The open source alternatives are better.

• Controller Error: Do I need to worry?

What is a ATAPI Error? Do I need to re-install Windows? I generally find the occurs when I try to backup my machine (using Windows Backup) or when using a program that uses Volume Shadow Copy. I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

• How to prevent nginx from locking files on mounted samba partition in Centos 6

  - by Bruce Kirkpatrick

  I'm using nginx 1.3.8 inside a centos 6.3 virtualbox 4.2.4 virtual machine. The system is running the latest software available via yum update. The host OS is windows 7. The site files nginx is serving are on mounted samba partition, which is a folder on the host Windows system. I.e., inside linux, nginx paths are referring to /home/vhosts and this is mounted from D:\vhosts\ on windows. The samba partition is mounted as root with 777 privileges. /etc/fstab looks like this, but with real ip, username, password: //hostip/vhosts /home/vhosts cifs username=username,password=SECRETPASSWORD,uid=root,gid=root,file_mode=0777,dir_mode=0777,rw,_netdev 0 0 I.e. linux/nginx reads from the windows share, and not the opposite. in /etc/samba/smb.conf, I have tried to disable all samba locking features, but it seems to have no effect even after rebooting the virtual machine. locking=no share modes=no oplocks = no level2 oplocks = no kernel oplocks =no I'm receiving "Access is denied" errors in Windows or linux when attempting to overwrite the javascript file in windows that has been accessed at least once with nginx. If I run "service nginx reload", the lock is removed and I'm able to save the file. That's why I think it is nginx causing the lock. The same problem occurs with directories. However, that may be a different issue not related to the use of samba. I'm using samba so that I can manage the source code outside of the virtual machine. Also note that after I run "service nginx reload", the file I'm editing is actually automatically deleted from the windows host. SOLVED: I just reviewed my nginx.conf file. It appears the "open_file_cache" feature is what is causing the lock and deleted files. When I set this option to open_file_cache off;, My problem is resolved. I will repost as the answer when it allows me to do so.

• supervisord launches with wrong setuid

  - by friendzis

  I am trying to test a pilot system with nginx connecting to uwsgi served application controlled by supervisord running on ubuntu-server. Application is written in python with Flask in virtualenv, although I'm not sure if that is relevant. To test the system I have created a simple hello world with flask. I want nginx and uwsgi both to run as www-data user. If I launch uwsgi "manually" from root shell I can see uwsgi processes runing as appropriate user (www-data). Although, if I let supervisor launch the application something strange happens - uwsgi processes are runing under my user (friendzis). Consequently, socket file gets created under wrong user and nginx cannot communicate with my applicaion. note: the linux server runs as Hyper-V VM, under Windows Server 2008. Relevant configuration: [uwsgi] socket = /var/www/sockets/cowsay.sock chmod-socket = 666 abstract-socket = false master = true workers = 2 uid = www-data gid = www-data chdir = /var/www/cowsay/cowsay pp = /var/www/cowsay/cowsay pyhome = /var/www/cowsay module = cowsay callable = app supervisor [program:cowsay] command = /var/www/cowsay/bin/uwsgi -s /var/www/sockets/cowsay.sock -w cowsay:app directory = /var/www/cowsay/cowsay user = www-data autostart = true autorestart = true stdout_logfile = /var/www/cowsay/log/supervisor.log redirect_stderr = true stopsignal = QUIT I'm sure I'm missing some minor detail, but I'm unable to notice it. Would appreciate any suggestions.

• Solaris Fibre Channel target - Configure QLogic QLA2340

  - by growse

  I'm currently trying to set up a small storage system as a fibre channel target. This is for testing, so I'm currently using Solaris (Nexenta) and a QLogic QLA2340 HBA. For some reason, the qlc and qlt drivers don't support the QLA2340, so I'm using the qla2300 driver from QLogic's website. I've also got the scli utility installed for configuration. The HBA is detected by the system. That said, it's not clear how I get from this point to a point where I have a ZFS volume being exposed as an FC target. I was originally following this guide (http://www.youtube.com/watch?v=yzEBd3l7Qn4) but it seems that without the qlc/qlt drivers, Sun's configuration tools won't work. Does that also imply that COMSTAR also won't work? What's the best way to expose an FC target with this setup? Most of the options I'm seeing in scli complain that the port state is LinkDown (it is, I've not plugged anything in yet). Do I have to have my FC client plugged up and working before I can configure the target? Apologies for the slight vagueness of the question, but I'm not overly familiar with the terminology.

• EC2 Configuration

  - by user123683

  I am trying to create a server structure for my EC2 account. The design I have chosen consists of 2 instances running in different availability zones, elastic load balancer, an auto-scaling group with cloudwatch monitoring configured and a security group defining rules for access to the instances. This setup is to support an online web application written in PHP. I am trying to decide what is a better policy: Store MySQL DB on a separate Instance Store MySQL DB on an attached EBS volume (from what i know auto-scaling will not replicate the attached EBS volume but will generate new instances from a chosen AMI - is this view correct?) Regards the AMI I plan to use a basic Amazon linux 64 bit AMI, and install bastille (maybe OSSEC) but I am looking to also use an encrypted file system. Are there any issues using an encrypted file system and communication between the DB and webapp i neeed to be aware of? Are there any comms issues using the encrypted filesystem on the instance housing the webapp I was going to launch a second instance or attach a second volume in the second availability zone to act as a standby for the database - I'm just looking for some suggestions about how to get the two DB's to talk - will this be a big task Regards updates for security is it best to create a recent snapshot and just relaunch and allow Amazon to install updates on launch or is the yum update mechanism a suitable alternative - is it better practice to relaunch instead of updates being installed which force a restart. I plan to create two AMI snapshots one for the app server and one for the DB each with the same security measures in place - is this a reasonable - I just figure it is a better policy than having additional applications that are unnecessary included in a AMI that I intend on using. My plan for backup is to create periodic snapshots of the webapp and DB instances (if I use an additional EBS volume instead of separate instances my understanding is that the EBS volume will persist in S3 storage in the event of an unexpected termination and I can create snapshots of the volume backup purposes). Thanks in advance for suggestions and advice. I am new to EC2 and I may have described unnecessary overkill but I want to try implement what can be considered a best practice solution so all advice is appreciated.

• Poor gaming performance with hyper-v installed in windows 8

  - by SnowCrash

  I am getting very poor gaming performance on my Windows 8 host OS with Hyper-V installed but no guest machines running. For example World of Tanks reports 60-70 FPS without Hyper-V installed and 4-14 FPS with it installed. A similar, dramatic, hit is observed in several other games so the issue is not WoT specific. To make the point clear, I am not trying to run games in a virtual machine. I don't even have a VM running while observing this effect. I simply have the Hyper-V feature installed. My system specs: AMD Phenom II 965 (3.4 GHz) AMD Radeon 6950 2GB (XFX Double D HD-695X-CDFC) 16GB DDR3 1333 AMD 790GX chipset Mainboard (Gigabyte GA-MA790GPT-UD3H) I have tried every AMD driver from 12.8 to the current 12.11beta8, virtualization is enabled in the BIOS settings, the onboard 3300HD video device is disabled in BIOS and I have read the MSDN blog entry here regarding a similar issue in Server 2008 that was resolved in 2008 R2 (and hopefully not regressed in Win 8). I'd like to be able to use Hyper-V for development and testing at home (I am a sysadmin/software developer professionally). If, however, I can't also use my home system for entertainment I'll have to scrap those plans.

• Tablet as Car Computer

  - by luxurychair

  Okay, so forward this off to the right place if this isn't the right place to ask this question. I want to use a tablet computer as a car-computer. Minimum features would be to run my music (through iPod, Pandora, whatever I want) and GPS Navigation, watch TV or movies while I'm parked waiting for people, and the hard one: it needs to answer my phone calls with a pleasant interface much like in-dash systems do. It needs to detect that my phone is ringing in my pocket and provide an on-screen answer/ignore and then route the audio through the cars speakers. It would be nice to dial out and have address book access, but that is somewhat secondary. I have an iPhone myself and I figured that an iPad with 3G might make a good system for this - but I'm open to other options if an iPad can't do everything I need. I'm willing to write code, and I'm willing to jailbreak one or both devices. I haven't done much work in Obj-C, but I'm not opposed to learning a new language for this project. It's self enrichment for the most part, as I'm sure I can buy an indash entertainment system for less. Does anyone have experience with the iPhone/iPad SDK that can tell me whether or not it would be possible to get it an iPad to answer my calls in the car? What about an Android tablet? (that Adam looks promising, too).

• Help Installing SQL Server 2008 Express Edition

  - by Jordan S

  Ok I am running Windows 7, 64 bit. I cleaned of SQL server 2005 completely off my system leaving only SQL Compact Edition. I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=01af61e6-2f63-4291-bcad-fd500f6027ff&displaylang=en and installed SQL Server 2008 Express Edition Service Pack 1. After the install, under my start bar menu all i have for SQL configuration tools are the Configuration Manager, Error and Usage Reporting and the Install Center. I don't have the SQL Managment Studio. So I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en and downloaded the SQL Server 2008 Management Studio Express but when I try to install it I get a warning says This program has known compatibility issues and that I need to Install SQL Server 2008 Service Pack 1. I thought that is what I installed. So, I tried to continue running the install but I then get an error message that says Invoke or BeginInvoke can not be called on a Form before it is opened... How can I check if Service pack 1 is installed or not? What should I do? Also I rebooted my system and checked for Windows Updates and it says that Windows it up to date.

• Mac OS X: which folders should ClamXav Sentry watch?

  - by trolle3000

  I'm using ClamXav on my Mac. I've read this, and I am aware of the whole Macs-need-no-AV-but-they-do-anyway discussion. I guess that's why I would feel like a real jerk if I somehow managed to compromise my system! So ClamXav has been downloaded and ClamXav Sentry set up to start on log-in, but it doesn't really do anything before you tell it to. Specifically, you have to tell it which folders to watch for virusses/vira so I'm wondering, where are good places to look? Currently it's been set up to look the following places: In the home folder: ~/Downloads ~/Library/Caches ~/Library/Contextual Menu Items ~/Library/Cookies ~/Library/Internet Plug-Ins ~/Library/LaunchAgents In my system folder: /Library/Application Support /Library/Caches /Library/Contextual Menu Items /Library/Cookies /Library/Internet Plug-Ins /Library/LaunchAgents /Library/LaunchDaemons /Library/Startupitems Basically, this is 100% conjecture. All (most of) the folders have something to do with the Internet and things that start up automatically, so I'm guessing that's where vira go. But still, the qustion: Which folders should ClamXav Sentry watch, if any? FYI, I'm not using any mail applications, but please include that in your answer for anyone who might be interested.

• Failed to mount to nfs server with "Program not Registered"

  - by Farrel

  I'm trying to setup nfs server on Fedora 17 and I'm getting "Program not Registered" error when I'm trying to mount. I guess the main reason for this is rpcbind. I'm a newbie in linux, so I don't know what info should I provide you with. Here is some info that might be useful. rpcinfo -p program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100005 1 udp 20048 mountd 100005 1 tcp 20048 mountd 100005 2 udp 20048 mountd 100005 2 tcp 20048 mountd 100005 3 udp 20048 mountd 100005 3 tcp 20048 mountd 100024 1 udp 42223 status 100024 1 tcp 50054 status cat /etc/exports /home/Farrel/prog 192.168.xxx.xxx (ro,sync) service nfs status Redirecting to /bin/systemctl status nfs.service nfs-server.service - NFS Server Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; enabled) Active: active (exited) since Fri, 02 Nov 2012 09:29:04 +0300; 5min ago Process: 924 ExecStartPost=/usr/lib/nfs-utils/scripts/nfs-server.postconfig (code=exited, status=0/SUCCESS) Process: 909 ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS ${RPCNFSDCOUNT} (code=exited, status=0/SUCCESS) Process: 885 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=0/SUCCESS) Process: 864 ExecStartPre=/usr/lib/nfs-utils/scripts/nfs-server.preconfig (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/nfs-server.service Warning: Journal has been rotated since unit was started.

• Umount stale glusterfs partition

  - by Khaled

  I am using glusterfs on several Ubuntu servers: two of them are running glusterfs servers in replication mode. Without any clear error, the glusterfs partition became stale and the system shows this error when I try to access the stale partition: Transport endpoint is not connected Also, when running ls -l on the parent folder I get: d????????? ? ? ? ? ? myfolder I tried all types of commands that I can find to umount this partition, but I could not get it done: umount -l /path/to/mount/point umount -f /path/to/mount/point Also, using fuser command to show processes accessing this folder did not work. Unload the fuse kernel module can not be done as it is clear from the kernel config that fuse is built into the kernel and not a loadable module. I found this line in /boot/config-2.6.32-24-server CONFIG_FUSE_FS=y I have been left with two options: Reboot the system. Create another mount point like myfolder2 and mount this again using sudo glusterfs -f /etc/glustefs/glusterfs.vol /path/to/folder2. Of course, I have chosen to go with option 2. Anyone faced such an issue before? Anyone has a better solution for such a case?

• GlusterFS on VMWare ESXi 5

  - by Dharmavir

  I want to build network file system on top of my VMWare ESXi based virtual nodes which are running Ubuntu 12.04 LTS. I am evalaluating options and found that GlusterFS (http://www.gluster.org/) can turn out to be a good choice. Purpose: I have about 2 dozen VM nodes with different configurations, on 2 physical nodes which has following configuration: 16 core Intel Xeon 1 TB 48 GB RAM Now as I said earlier each Physical server has about 1TB hdd and I can increase if I want additional so for now I have 2TB disk space available, these space is distributed in VM nodes I have created on which about 2 dozen VM nodes live. Now some of them being application server and mgmt server, they have plenty of free disk space which I want to utilize for some heavy storage which I can not design if I do that individually on single VM node. This way if my storage is distributed between dozens of VM nodes and about 2 or more physical nodes I have some sort of backup as well. I do not mind if data gets stored redundently but per my knowledge it might hapeen that individual VM nodes will not be able to store all of the data because complete data size for example if we take 100GB will exceed VM disk size of 70GB and then VM will also have system and program files on it. I need some suggestion that will GlusterFS be the solution for which I am looking forward to or I should go with something like hadoop? I am not too sure. But yes, I would like to utilize my free space on each VM node and while doing that if I get store data redundently I am okay because it will give me data security.

• Windows Server 2008 R2 install reboots unexpectedly during "Completing installation" phase

  - by knda

  I am attempting to install Windows Server 2008 R2 onto a Cisco UCS C201 M2 rack mounted server but am having major difficulties and wondering if anyone has some insight or items they could recommend for me to look at to get this one resolved. Installation is being attempted via the Cisco remote console (using CIMC's Virtual dvd-rom).. following the first phase of Setup where the installation files are copied to the target hard drive, then a reboot occurs to load Setup from the HDD, mid-way in the "Completing Installation" phase the system then reboots unexpectedly. System configuration Cisco UCS C201 M2 (2RU rack mounted server) 16GB RAM, 2x 73GB 15K SAS, 4x 300GB 10k SAS Add-on cards - Intel quad-port GigE card (no fibre channel cards) Storage - LSI MegaRAID SAS 9261-8i. onboard SATA is disabled (no SATA drives connected) KVM - Belkin No physical DVD-ROM.. :( I have... Run memtest86+, no RAM faults Disabled/enabled SATA support (BIOS) Attempted install from USB DVD-ROM, no effect Attempted unattended install scripted via Cisco Configuration Manager DVD provided Removed Belkin KVM in case that was causing drama Discovered that the Cisco website is "awesome" for searching for PDFs/Drivers cough, reverted back to Google Downloaded latest LSI drivers from LSI's site and used during Server 2008 install checked Windows ISO against checksum's from MS site checked Windows ISO by using it for an install in a VM Running out of ways to troubleshoot this as I am not sure how to enable any sort of 'verbose' mode during the setup process. Next step I have planned is to remove the Intel NIC and try the installation again.. Edit: Problem was the "Cisco INTEL QUAD PT GBE" (1000/PT) .. will have to see if this card is faulty or if it's just drivers.. thanks for the help.

• Pentium 4 Willamette vs. Faster Celeron Northwood [closed]

  - by Synetech inc.

  Which is the preferable of the following two processors? Intel® Pentium® 4 Processor 1.70 GHz, 256K Cache, 400 MHz FSB Willamette Intel® Celeron® Processor 2.40 GHz, 128K Cache, 400 MHz FSB Northwood Details: A few months ago my motherboard died, so I bought a used computer that had a 2.4GHz Celeron. My old system had a 1.7GHz Pentium 4, so now I’m trying to decide which CPU to use. Obviously a P4 is preferable over a Celeron, but the Celeron is (significantly?) faster than the P4. I’m wondering if the faster Celeron might be better for certain tasks (ie, stronger but dumber is better at some things than smarter but weaker). I tried Googling for some reviews and comparisons for graphs to get a clear depiction of which is better overall, but found nothing that helped. (I did manage to find one page that indicates (apparently by poll, not benchmark) that the Celeron is better.) So which CPU should I use? Does anyone know of some graphs that I can use to compare the two? The system is a general-purpose machine for word-processing, Internet, and casual games (not Crysis, but not Solitaire either). It will be running Windows XP. The board is a 478 with 400MHz FSB.

• Keyboard's media keys are blocked by a program

  - by Mike Hanson

  I've got a Microsoft Natural Ergonomic Keyboard 4000. In addition to the regular keys, it's also got keys for Web/Home, Search, Mail, Favorites (5), Calculator, and Media functions (Mute, Volume Up/Down, and Play/Pause). Everything works most of the time, and the exception is rather odd. I use a programming system called Clarion. When that has focus, the Media keys don't work. (All the others still do.) I've also discovered that programs that I create using Clarion also block the media keys (only when they have focus). This indicates that it's probably something in Clarion's Run-Time Library (RTL) that's causing the trouble. The keys will work if I click on a non-Clarion window before hitting the media key, but that's an undesirable hassle. The odd thing is that I have many colleagues with the same keyboard, and they have no problem. When I recently upgraded from Vista Professional to Win7 Ultimate, I noticed that various things "appear" differently. For example, with my old system, when I changed the volume or muted the volume bar visualization always appeared at the bottom right on the screen. Now it doesn't appear in certain programs, even when it works. This indicates an order of precedence for visual elements. I'm fairly certain a similar order of precedence exists for keyboard hooks. Depending on how the hooks are defined, and the order in which they're applied, it would seem that sometimes the IntelliType drivers don't see the media keystrokes. The Media keys probably behave differently than the rest of the "special" keys, because they are more of a standard across all keyboards, so perhaps are handled by a different driver hooking mechanism. Does anyone have any suggestions of how I might fix this problem? Is there some way to change the order of hooks? Delay the loading of the IntelliType driver? Thanks in advance!

• Cannot Install Bootcamp on Mac Fusion Drive

  - by user3377019

  I have two drive installed in my mid-2013 Macbook pro. It is running osx maverick. I set the two drives (an ssd and a regular HD) up using the fusion drive (following the diy fusion drive guides out there). I went ahead and created a 40gb partition to host my windows install. I removed the SSD, installed windows, then reinstalled the SSD. As soon as the ssd was placed back in the bootcamp partition stopped booting. I get a blinking cursor on a black screen. I checked out the partition info in disk utility and it appears that the windows partition is not marked bootable. Below is some info I managed to gather. I am wondering if there is a way to fix the partition table so my bootcamp will boot. /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *120.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage 119.7 GB disk0s2 3: Apple_Boot Boot OS X 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk1 1: EFI EFI 209.7 MB disk1s1 2: Microsoft Basic Data BOOTCAMP 40.0 GB disk1s2 3: Apple_CoreStorage 459.2 GB disk1s3 4: Apple_Boot Boot OS X 650.0 MB disk1s4 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Macintosh HD *573.4 GB disk2 Name : BOOTCAMP Type : Partition Disk Identifier : disk1s2 Mount Point : /Volumes/BOOTCAMP File System : Windows NT File System (NTFS) Connection Bus : SATA Device Tree : IODeviceTree:/PCI0@0/SATA@1F,2/PRT1@1/PMP@0 Writable : No Universal Unique Identifier : 584BAED6-4C46-4F18-93B3-957F6E27003C Capacity : 40 GB (39,998,980,096 Bytes) Free Space : 16.34 GB (16,339,972,096 Bytes) Used : 23.66 GB (23,659,003,904 Bytes) Number of Files : 86,424 Number of Folders : 0 Owners Enabled : No Can Turn Owners Off : No Can Be Formatted : No Bootable : No Supports Journaling : No Journaled : No Disk Number : 1 Partition Number : 2
