• b43 module loaded, but no interface showed up

  - by Eduardo Bezerra

  I'm using CentOS 6.3 x86_64 on a hardware with a BCM43224 chip for wi-fi. I installed the b43-fwcutter module and then run modprobe b43, with no error messages. However, no new network interface showed up, and the return of iwconfig is: lo no wireless extensions. eth0 no wireless extensions. lspci -nn | grep 43224 returns: 03:00.0 Network controller [0280]: Broadcom Corporation BCM43224 802.11a/b/g/n [14e4:4353] (rev 01) and uname -a: Linux localhost.localdomain 2.6.32-279.14.1.el6.x86_64 #1 SMP Tue Nov 6 23:43:09 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Any ideas of how to make the wireless device work?

• Weather Logging Software on Windows Home Server

  - by Cruiser

  I'm looking for some weather logging software that I can run as a Windows Home Server add-in, or as a service on my Home Server, so I don't need to log into my Home Server to log weather data. I have an Oregon Scientific WMR918 weather station, and an HP MediaSmart EX485 Windows Home Server. The two are currently connected through a serial bluetooth adapter, but that shouldn't matter as the computer sees it basically as a serial device. I'm currently using Cumulus to log data and upload to Weather Underground, but it is a regular windows application, so I need to remain logged into my Home Server by RDP in order to run the software (I disconnect, but don't log off so the session remains open). Ideally I would like something to run as a service or WHS add-in, so that it runs all the time without logging in, can log data from my WMR918, and can upload to Weather Underground. Thanks!

• HP Proliant ML115 G5 - Boot order lost after reboot

  - by Filipe YaBa Polido

  I have one HP Proliant ML 115 G5 (AMD) with the latest BIOS (07-06-2009) and recently I've installed an USB disk. This is a common problem on old Proliant servers. When you plug the USB disk, BIOS boot order changes and tries to boot via USB. So, I'll change the BIOS settings and make the SATA disk the default boot device. The problem is, when I need to unplug the usb disk, and plug it again later. I can't be always changing the BIOS settings... How can one solve this for ever?!?!

• tradeoffs of iSCSI vs. AFP when using Time Machine with a NAS?

  - by Ajit George

  I'm setting up a home NAS device (Synology DS409) that I'm planning to use for Time Machine backups (amongst other things). What are the tradeoffs between using iSCSI or AFP to mount the backup volume? The Synology wiki suggests that iSCSI is better if the Mac will be frequently disconnected from the network or sleeping, from the point of view of the volume automatically remounting. What about filesystem consistency? Given that unplugging a USB drive without properly unmounting it often requires the Time Machine volume to be repaired, would iSCSI have the same issues?

• PS/2 vs USB keyboards: performance and energy consumption

  - by Mister Smith

  As far as I know, PS/2 keyboards are interrupt driven, while USB are polled. Typically a PS/2 keyboard was assigned IRQ_1 on Windows. I'm no hardware expert, but at a first glance seems like the PS/2 keyboards are more efficient. So here are my questions: On modern day computers, are PS/2 keyboard better (or faster), and if so, would it be noticeable at all? (e.g.: in gaming) Since they don't need polling, do PS/2 keyboards save energy compared to USB? (notice I'm not talking only about the peripheral here, but about the overall computer energy consumption). In case PS/2 had any advantage over USB, would adding a PS/2 adapter to my USB keyboard make the device as good as an actual PS/2 keyboard? Conversely, would adding a USB adapter to a PS/2 make it as bad as a USB KB? Thanks in advance.

• No network adapter drivers after Windows re-install

  - by Arno

  This is a pretty basic question. I got a PC (Packard Bell Easynote TK11-BZ-010BE) that had linux on it, so I thought, just delete the partition and its alright. Well, it wasn't. I went into grub recovery and couldn't do anything, so I re-installed windows again. Now the problem is that everything works expect my network adapter. When I go to device manager, I get that there aren't any driver's for it installed. But without internet, I can't install the so called driver finders. How should I solve this?

• Just bought Logitech G35 headset, want to enable/disable headet in one action

  - by Roy Rico

  Hello, Just bought Logitech G35 USB headset, want to enable/disable headet in one action. I have windows 7 64 bit, and currently, to switch from the headset to my spakers (or vice versa) without unplugging the headset, i have to go thru this steps: right click on the sound icon select "sounds" select the "Playback" tab right click headset and hit enable right click speakers and hit disable same steps when wanting to switch back I have to disable the devices, because not all of the programs which are outputting sound will switch immediately if I just set either device to default. I am looking for this to be a single action (either a batch script or a windows shortcut to some action with parameters?) Thanks!

• dell vostro 1310 with nVidia 8400M display problem

  - by Arthur

  Hi everyone, i hope someone can help me with this problem. I have a Dell vostro 1310 Laptop with 32 bit vista and a 8400M nVidia chip. Recently i have noticed performance issues when my girlfriend was playing Sims 3, and then one day i turned it on and all i got was a thick white line at the bottom of the screen. i heard the OS start up so automatically i thought it was a damaged screen, but i had doubts so i plugged it into an external display via the vga port. it worked but everything appart worm the OS choice menu looks distorted beyond belief. even the bios screen had multicoloured lines running down the screen. The resolution is non existant, the screen only shows a 256 colour pallette and is heavily distorted. i barely managed to get to the device manager where i found the gfx card with an exclamation mark. does anybody have suggestions? should i buy a new mobo or are repairs possible? thanks in advance

• Disable PXE progamatically in parallels?

  - by Stefan Lasiewski

  I'm running Parallels 4.0 on Mac OS X 10.5.8. I'm trying to create a bunch of Virtual Machines from the commandline, using the prlctl tool, like so: $ prlctl create test1 -o linux -d centos $ prlctl set test1 --device-del cdrom0 $ prlctl start test1 Now, each time I start a new VM, the VM spends time waiting for a PXE boot. I'd like to turn this off. Can I disable PXE requests using Parallels or a Parallels commandline tool? Or, can I set the boot order of a VM from the commandline?

• Good quality voice communication software over Internet for windows

  - by ORA600

  I regularly attend over-the-phone meetings, where is a polycom/polispan device on the other side. The quality of the sound is bad, even those whose English is a first language sometimes are struggling to realize what is being said on the other side. I understand this is because of too aggressive audio compression in the line. Does anyone know any good audio chat software which does not over-compress audio stream. The IP channel between two offices is wide enough. In other words, you should be able to listen to a music (not only a speech) from the remote side with good quality. So, Skype is too over-compressing as well. Does anyone know anything like that?

• Can't find generic USB audio driver for a Samson COU1 USB microphone

  - by marcipollo

  I am unable to use a Samson USB CO1U microphone on a PC running XP, SP3. When I plug it into the USB port, Windows generates the sound indicating that it has found new hardware, and the green LED on the mic lights. But, it does not work, and the device manager reports that it cannot find a driver after searching. The same mic works on a Vista machine. Samson has no driver on their Web site, and insists that the generic audio driver in Windows should work. (http://www.samsontech.com/PRODUCTS/productpage.cfm?prodID=1810). I cannot find a generic USB audio driver at Microsoft.com. Can anyone help? Larry

• Format External HD on Airport Extreme Base Station?

  - by David.Chu.ca

  I just got an Airport Extreme Base Station. I am planning to use this one replace my current Linksys router. This works fine. My another purpose of getting this device is to use its USB port to connect to several external HDs as my backup Time Machine. I can see one 500GB HD through Airport Base Station. However, I cannot format it by using Disk Utility. What I did is to connect the HD to my iMac directly first and then clean and format the disk by Disk Utility application. Then I move the HD to the Airport Base Station. After that I can designate the HD as my Time Machine destination. Is there any way to format the HD connected to Airport Base Station? Any issues to use an external HD through Airport Base Station for Time Machine backups?

• Question about the linux root file system.

  - by smwikipedia

  I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My questions are: Where is this "big tree" located? Suppose I have 2 disks, if I mount them onto some point in the "big tree", does linux place some "special marks" in the mount point to indicate that these 2 "mount directories" are indeed seperate disks?

• SCCM deploy from VMware XP image

  - by HannesFostie

  We recently set up the latest version of SCCM and I managed to capture a .wim image from a virtual machine (build and capture task sequence). I want to use this .wim file to deploy winXP to different hardware, and therefor need to add device drivers to the task sequence. I created a driver package per laptop type, and deployed for the first time. However, I am getting a BSOD (0x00007B) which leads me to believe theres a problem with the storage drivers. After adjusting the task sequence to try and point to the mass storage drivers (which are applied at F6, I suppose) I do not get a list of compatible drivers (the list is empty). I looked around, and found some issues regarding hdc class drivers that are not recognized as mass storage drivers. The workaround suggested changing the INF file to make the driver a SCSIAdapter class driver, and importing these again, but to no avail. The list remains empty. Any help is much appreciated

• backup software that ignores user rights

  - by Chris

  Hi, As a computer technician I have to reinstall systems allmost daily (when it can't be repaired ;-)) My problem is that I recover user files by hand and a external mounting device. Most of the time it works fine, but also weekly I have systems with passwords and personal files which are often not sucessfull recovered. I know you can change owner, but when people have 30 GB's af data, my backup computer works for ages to change the rights. Can anyone think of software (commercial is no problem) which does the following: * backup user data without having user rights troubles * have a option to choose what to backup (email accounts, documents, etc, etc) even when it's externaly mounted, in short, it reconizes the folder structure) * Works on different OS's like XP, Vista, W7

• HP DL380 G5 Predictive Drive Failure on a new drive

  - by CharlieJ

  Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

• Symmetrix gatekeepers on Solaris 10

  - by Milner

  I have some Solaris machines that are connected to EMC Symmetrix for SAN storage. Apparently the Symm has a gatekeeper device that is used with the symmetrix CLI. We don't need the CLI, but I have these gatekeeper devices that constantly fill /var/adm/messages and the like with corrupt label errors. Is there anything I can do (short of deleting the devices on machine start) to get rid of them? Or should I just try to get our SAN guy to get the installer for the CLI? These things are getting annoying, and the devfsadmd daemon keeps rediscovering them on boot.

• 2nd/3rd version of wireless network appears

  - by neildeadman

  I replaced an old SpeedTouch ADSL router with a Netgear DG384 that I have and whilst doing so decided to change the wireless password. For this question assume my wireless network SSID is DeddersHome. On my netbook and macbook pro (running Win7) it won't connect to the Internet. When I hover over the tray icon for wireless it says "DeddersHome 2" and "DeddersHome 3" have no internet connection. What are these additional wireless networks? I can't see them in the wireless network list on any wireless device I have. Wired connections and wireless through my iPhone work fine. I saw this before with the SpeedTouch, but it just went away!! I also have one Apple AirPort Express connected to the wireless network which my Xbox is connected to (wired). This all worked before... I am going to remove AirPort to see if it is this causing the problem, but thought I'd ask the question to give it time for an answer whilst I continue to search. Cheers

• Does Windows 7 support multiple simultaneous nVidia graphics cards with different drivers?

  - by mckenzieg1

  On one of my dev machines at work (currently running XP), I have two nVidia graphics cards: Quadro NVS 440 (my original card, for my three primary monitors) GeForce GTX 275 (just added, for CUDA development) I can get both cards to work OK by installing the latest GeForce drivers, but I get some annoying-but-not-crippling display artifacts on the Quadro's screens (mostly scattered black rectanges where repainting fails for a few bits of UI in certain applications). Under XP, this seems to be the best I can do. I can use Device Manager to supposedly install different nVidia drivers for the two cards (the latest Quadro drivers for the NVS, the latest GeForce drivers for the GTX), but I actually end up with the same driver for both, because the driver dlls all have the same names and get installed on top of one another in the system directory. I have read that Win7 has a new video driver architecture that better supports multiple heterogeneous cards. Does anyone know if that will handle my scenario? If so, it will give me a compelling reason to get that machine on Win7 ASAP.

• Dye Sub printer with specific prints remaining - can I command-line query this?

  - by Jason N

  Hey, I've got a Sony Dye-Sub printer that holds ink/paper sets - i.e. a very certain amount of ink and paper for ~200 prints. This information is available to me from within Control Panel Printers Preferences Printer Device Information (i.e. current 189 remaining prints). Any way I can perhaps get this information from the command line? I'd like to write a little program to tell me when the number of prints gets low (i.e. < 20), rather than suffer the annoying Windows "run out of paper" popup. I've found the Windows VBScript print utilities, but can't seem to find the request I need for this. Any suggestions? Jason

• Easy way to restrict permissions in an elementary school computer lab?

  - by Andrew

  I'm putting together an elementary school computer lab. I have nine winxp pro machines that are not networked and do not have internet access (no money to do either). I've created separate student and admin accounts, and have the students set as limited users. However, I'm interested in further restricting their permissions. I want to make it such that they cannot: -delete any files, even just from their own profile -rename any files -move around the icons on the desktop -change any display settings -access a usb device without a password (they bring in their own from home which are chock-full of viruses) Oh, one last thing, they still have to be able to save word documents. Is this even possible? I can download software, but, like I said: no internet, no server.
