• How can I tell if I have PCI Express 2.0 or 2.1?

  - by Stefan Lasiewski

  I am looking at a variety of PCI Express cards, such as a SATA RAID Controller and a Video Card. Some of these cards say they only support PCI Express 2.1, not PCI Express 2.0. I know that my motherboard supports PCI Express 2-something, but the manual doesn't say '2.0' or '2.1'. How can I tell if the PCIe slot on my motherboard is PCI Express 2.0 or PCI Express 2.1? Is it possible to determine the PCIe type from the Windows or Linux commandline? I was under the impression that most PCI Express 2.1 devices are backwards compatible with PCI Express 2.0. Is it possible that the vendor is wrong in saying that PCI Express 2.1 is required?

• Using a buffalo wl12-pci-g54s on Debian Linux

  - by Nic Hubbard

  I have a buffalo wl12-pci-g54s wireless card that I want to install in my PC running Debian. I need this so I can move the server to a better location in another room. So, is there an easy way to do this? Some package that I can install and get up and running? Other instructions that I found online have been confusing. I am also using a static IP, so I need to retain that when I make the switch. Thanks!

• How can I make Windows Media Player ignore global hotkeys in Windows 7?

  - by schnapple

  I have Windows 7 and a Logitech G15 keyboard. One of the programs with the Logitech G15 allows you to control media players such as Winamp with the playback keys on the keyboard. Problem I'm having is that, even though I have told this program to not control Windows Media Player, every time I use it to pause Winamp, it then hits plays (or unpauses) Windows Media Player. Even more annoying given that Windows Media Player isn't even running as an active GUI program and instead as a background process, so I hear the sound of whatever the last video it was I playing. If I end-task wmplayer.exe it spins right back up but at least now it has no knowledge of a video to play, but this is annoying. How can I either a) Have Windows Media Player in Windows 7 completely unload when I close it, or b) Have Windows Media Player in Windows 7 ignore any sort of global hotkeys?

• What should I know before I set up RAID 6 on Linux?

  - by Dan Ellis

  I just ordered five 1TB drives to install as a RAID 6 array in a Linux server (keeping the existing 1TB drive as a boot disk). I want to use Linux MD for RAID rather than a RAID card, to avoid lock-in. The intended use is for storing filesystems for Xen development environments and an AFP server for iPhoto/Aperture/Lightroom. What things should I know before I set it up? For example, what would be a good choice of filesystem, and what chunk size should I use?

• What is meant by the terms CPU, Core, Die and Package?

  - by lovesh

  Now this might sound like too many previous questions, but I am really confused about these terms. I was trying to understand how "dual core" is different from "Core 2 Duo", and I came across some answers. For example, this answer states: Core 2 Duo has two cores inside a single physical package and dual core is 2 cpu in a package 2 cpu's in a die = 2 cpu's made together 2 cpu's in package = 2 cpu's on small board or linked in some way Now, is a core different from a CPU? What I understand is there is something that does all the heavy computation, decision making, math and other stuff (aka "processing") is called a CPU. Now what is a Core? And what is a processor when somebody says he has got a Core 2 Duo? And in this context what is a Package and what is a Die? I still don't understand the difference between Core 2 Duo and Dual Core. And can somebody explain hyper-threading (symmetric multi-threading) too if they are super generous?

• Wireless network unavailable, no networks found after Windows update

  - by jacobsee

  Old Dell Inspiron 8200 laptop with Linksys Wireless G network adapter card (WPC54G v2). Wireless connection was working fine. Then I ran a bunch of windows updates, I think the last one was the recent .NET 3.5 service pack update. Now wireless networks won't connect. Using windows to manage wireless, no networks show up. I'm typing right now on another laptop where wireless is working fine. I've restarted router & Dell laptop several times. Tried to Repair wireless connection and refresh network list. Also restarted DHCP and WZC service, all to no avail. I then uninstalled .NET 3.5 SP (don't remember number) and .NET 3.0 SP2. I don't remember all the windows updates that I just ran because I haven't used this laptop in a while so had to catch up on some updates.

• Can unexpected power loss harm a Linux install?

  - by Johan Elmander

  I am developing an application on a Linux embedded board (runs Debian) e.g. Raspberry Pi, Beagle Board/Bone, or olimex. The boards works on an environment that the electricity is cut unexpectedly (it is far complicated to place PSU, etc.) and it would happen every day couple times. I wonder if the unexpected power cuts would cause crash/problem on the Linux Operation System? If it is something that I should worry, what would you suggest to prevent the damages on OS against the unexpected power cuts? PS. The application needs to writes some data to the storage medium (SD card), I think it would not be suitable to mount it as read-only.

• development and music recording machine suggestions?

  - by dean nolan

  I wasn't sure if this belongs on SuperUser so flag if so. I am looking to build, primarily, a windows development machine that is also good for recording using Cubase. I know I should use seperate machines but I'm on a budget this time of year. I also havn't kept up with hardware for quite a few years. Basically I know I want quad core, multiple monitor support (no gaming requirements). A lot of RAM, very quiet case and super fast HDD (SSD OR 10,000RPM)for compiling and latency. I will store libraries and other data on a USB drive. Sound card is not needed as I will be using an audio interface, all other music recording equipment is taken care of also. I could do with some decent monitor recomendations also. All suggestions welcome, thanks.

• How to get monitor resolution of 1680x1050 using ATI Radeon HD 2600 PRO in a dual monitor setup

  - by pratikk

  I have Sapphire ATI Radeon HD 2600 PRO graphics card in my Windows Server 2008 x64 machine. It has two outputs a VGA and a DVI. I have connected the DVI to my Dell 24" monitor with 1900x1200 resolution and it works 100%. The VGA I have connected to my second monitor a Samsung 22" with native resolution of 1680x1050. But the ATI driver and Catalyst control centre doesn't show this resolution as an option. If I choose a lower resolution like 1280x1024 it looks really bad and fuzzy. I searched in google and downloaded the powerstrip tool that allowed me to create a custom resolution of 1680x1050 and then this option shows up in Catalyst control centre and my 2nd monitor works fine now. But I don't want to pay for an application to choose a display resolution. Why doesn't ATI show me that option by default even though it has no problem in actually supporting the display at resolution. Is there a way to get 1680x1050 resolution using ATI drivers only ?

• Need Recommendations: Network Software and Hardware Setup for small firm

  - by Rogue

  Will be starting a small graphics design firm soon, with 20 employees. Therefore need software to manage the network. Have bought a bulk license of Windows 7. I have a spare computer which can act as a server if necessary, but its an ancient Dell machine (Pentium-III). If required I would purchase an extra machine, but would like to avoid unnecessary costs at start up. Following are the main functions that I would like to perform: Need to monitor\control network traffic and internet usage, restrict access to certain websites Alerts when access to certain software's, and when trying to tamper with privileges Ability to view desktops of any computer at any given time Limit access to certain hardware like USB ports,etc Limit access to folders on the computer Log/Report of all actions including keystrokes performed on any computer Local Network chat and talk client Collaboration and Work logs Any Software available to do all of the above and also any additional hardware required besides network switches, network card's and CAT5e cables. Any other recommendations besides the above mentioned hardware setup

• Testing domains on intranet/local network?

  - by meder

  This may sound like a very silly question, but how could I setup domains ( eg www.foo.com ) on my local network? I know that all a domain is, is just a name registered to a name server and that nameserver has a zone record, and in the zone record there are several records of which the A Record is the most important in dictating where the lookup goes to, which machine it should point to. I basically want to make it so that I can refer to my other computer/webserver as 'www.foo.com' and make my local sites accessible by that, mess with virtualhost records in Apache and zone records for the domain except locally so I can explore and fiddle around and learn instead of having to rely on the domains I own on a public registrar that I could only access through the internet. Once again I apologize if this is a silly question, or if I'm completely thinking backwards. Background information: My OS is Debian, I'm a novice at Linux. I've done very small edits in zone records on a Bind9 Server but that's the extent of my networking experience.

• Using a Raspberry Pi as a VPN?

  - by sudo rm -rf

  So I'm sure many of you have heard of the new Raspberry Pi project. I was looking at messing around with Model B, which has the following relevant specs: Broadcom BCM2835 700MHz ARM1176JZFS processor with FPU and Videocore 4 GPU 256MB RAM Boots from SD card, running the Fedora version of Linux (ARM Version) 10/100 BaseT Ethernet socket USB 2.0 socket So I was curious if it would be possible to create a simple VPN out of this little machine. I do realize that since it's an ARM processor that might mess up quite a few things. Any ideas if this is possible? Just for what it's worth, this would be a personal project so I'm not worried about performance.

• Flash not Working in Google Chrome for Mac

  - by Blakeasd

  Flash has randomly stopped working in Google Chrome for Mac. All that appears is a white flash then nothing. I can hear sound, and when I right click on where Flash is supposed to be I see the Flash Player options. I have completely reinstalled Chrome, including deleting all of its support files. I reinstalled my system flash and tried making Chrome use my system flash, but nothing works. Flash is fine in Safari, but not in Chrome. How do I fix this? I am running the latest Google Chrome Dev build (21.0.1171.0) and Mac OS X 10.7.4 . Thanks!

• Archive Recorded Show from DVR

  - by BillN

  IF I have an AT&T U-Verse DVR, is there a way to copy the information off the DVR to an PC for Archiving/burning to a DVD? I know that I could connect the A/V outs on the DVR to the A/V inputs on a DVD Recorder, or to a capture card on a PC, and Play the show, and record in real-time on the DVD or PC, but if the show is say a World Cup Game, this would take 2-3 hours per. My thought is that the DVR is just a HardDrive, and the files have to be stored in an digital format, it should be possible to do a copy of some sort. I'm currently recording all of the WC games, but if I don't watch them right away, I'm concerned that I will push other programming that the rest of the family has recorded out, making me unpopular at home. Note, I'm talking about archiving for personal use, not redistribution or anything.

• Can I "reprogram" an American Express USB drive?

  - by SkippyFire

  I recently received a USB drive that looks like a credit card as a promotion. The drive portion flips out to plug it in. When you plug it in, it opens the run dialog, and opens a URL to an American Express web page. I was able to find it in the Device Manager: But I don't know what else to do? Is there a way I can convert this into a plain old USB drive? Or better yet, can I modify the command that it runs when inserted into a computer?

• How do I configure an ordinary TV remote control to work with lirc on Linux?

  - by Allan Lewis

  I am running MythTV on Ubuntu 9.10 and I would like to use a TV remote to control it. I know that lirc needs a configuration file for the remote, but none of my remotes is in the official database. If I point a remote at the receiver on my TV card (a Pinnacle PCTV "Solo", model 72e) and press a button, dmesg logs the code generated by the remote, so I assume I just have to make a config file with a list of commands assigned to these codes. I've read a few how-tos but I still don't understand exactly how to create the config file. Some of the guides I've read refer to IR receivers on TV cards working at a "higher level of abstraction", which I take to mean that they decode the signal and provide a code, like the ones I can see in dmesg, rather than just giving raw data, but none of them explain where to go from there! Any help would be greatly appreciated!

• windows 7 losing wired ethernet connection

  - by Brandon Grossutti

  i have a win 7 machine with an Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller with latest drivers, the machine is upto date with all latest fixes etc. I have it connecting to a WRT310Nv2 router. Seemingly random, win 7 disconnects from the "Home Network" says its in a "public network", then resets the connection to an illegal 169 address. I have tried static ips, dhcp, all with the same results. This seems to have started shortly after i installed Vuze, so I uninstalled it but the problem persists. I know that the router is sound given that I have an XP machine attached with no issues of connectivity at all. I am at a complete loss and have tried everything, pleasse tell me i'm not the only one.

• Windows Disk I/O Analysis

  - by Jonathon

  It appears that we are having a problem with the disk i/o speed on our Windows 2003 Enterprise Edition server (64-bit). As we were initializing a database that created two 1G tablespaces on 3 different machines, it became obvious that the two smaller machines (each 32-bit Windows 2003 Standard Edition with less RAM) killed the larger machine when creating the files. The larger machine took 10x as long to create the tablespaces than did the other machines. Now, I am left wondering how that could be. What programs or scripts would you guys recommend for tracking down the I/O problem? I think the issue may be with the controller card (all boxes are hardware RAID 10, but have different controller cards), but I would like to check the actual disk I/O speed as well, so I have some hard numbers to work with. Any help would be appreciated.

• How can I share a Windows 7 library with anonymous access without using a Homegroup?

  - by Triynko

  The "homegroup" feature is useless, because it requires a password, and therefore doesn't support anonymous, no-hassle access to shares from devices such as my Sony Bravia TV and non-Windows7 machines. So I turned off homegroup and reverted to the standard shared folders protocol. I'd like to share my Music "Library", so I can play files from my TV through the Surround Sound System, but there seems to be no option to share a library folder other than through a homegroup. I don't want to have to individually share the folders that belong to the library, because that would defeat the purposes of the library, which is to manage which folders are included in the library while also providing an easily accessible view of them all at once. Does anyone know how to share a Windows 7 library without that useless homegroup feature?

• Monitor flashes black when starting video files, opening folders with video files

  - by Bob

  My entire monitor flashes black for a second or so when starting any video file. It does the same thing when closing the file. It also does this when opening a folder that has video files and a thumbnail view, or when I do anything that presumably accesses the video stream inside a video file. It happens in VLC and Windows Media Player, though it occurs to me certain video editors I have like avidemux and virtualdub don't have that issue when opening video files... It also does not happen when watching flash-based videos on web sites. It doesn't seem to happen when Quicktime. I went through and uninstalled any extraneous programs a week or so ago and didn't see any change. I also updated the graphics card driver. What can I do to troubleshoot/fix this?

• Cables for building a computer

  - by Faken

  I'm looking at building a computer and I have already done a whole bunch of research the topic and I think I know what I'm doing. My question is where do all the cables required for connecting everything come from? I'm pretty sure that the cables required come from their respective components (power connectors from the power supply, assorted cables from the motherboard, ect). However nowhere have I seen it explicitly stated that the cables come with the component I am buying. Just to confirm, if I buy all the components needed for a basic computer (CPU, motherboard, power supply, case, ram, video card, hard drive) from a website, say newegg, will I have all the screws, cables,connectors, and components to put together a working computer or will I need to buy some cables somewhere?

• Xerox Workcentre 3119 and Linux

  - by Milan Babuškov

  I'm trying to get Xerox Workcentre 3119 printer to work on Linux. It's a multifunction device (printer and scanner). I run the CUPS web interface at: http://localhost:631/ and it recognizes it on USB port and even suggests Gutenprint driver from the list. When I try to print a test page, the printer goes through "warming up" process (i.e. lights blink and sound is heard) but does not print anything. There are no errors in /var/log/cups/error_log and access_log shows as if everything is ok. The printer works fine in Windows XP. Does anyone have any experience with this printer on Linux?

• Can't delete a directory on external drive (OS X)

  - by Martin Tóth

  I have a brand new Transcend StoreJet 25M3 (external HDD) mounted to MacBook (Leopard 10.5.8) at /Volumes/Transcend. I copied some data from my old Windows (XP) machine on it, and now, after cleaning some stuff up, I wanted to delete some directories, but this is what happened: $ rmdir My\ Pictures/ rmdir: My Pictures/: Operation not permitted Using Finder just asks for password, but does not delete the directory (sound of "moved to Trash" is played). I thought it's some permission "thing", but: $ ls -l drwxrwxrwx 1 martin staff 32768 5 jan 16:11 My Pictures/ $ sudo rm -rf My\ Pictures rm: My Pictures: Operation not permitted I re-mounted, rebooted (thinking that there's some file lock), but that did not help. What might have happened here? How to delete it?
