• How do I resolve BSOD: PAGE_FAULT_IN_NONPAGED_AREA?

  - by Burnzy

  I have been trouble shooting this for a few days and cannot fix this anyhow. Computer specifications Mobo: ASUS Sabertooth X58 LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard CPU: Intel(R) Core(TM) i7 CPU 920 (Bloomfield) @ 2.67 ( no OC ) RAM: 6144MB RAM GPU: 2x NVIDIA GeForce GTS 250 1Go in SLI (sli is not enabled anyway at the moment anyway) Drives: OCZ RevoDrive OCZSSDPX-1RVD0120 PCI-E x4 120GB PCI Express MLC Internal SSD [RAID-0]. (I know this could potentilly cause trouble but I had the BSOD before using this drive) Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive - Bare Drive Click here for a log of a crash I just had. Click here for a log of a crash I had 30 minutes later, note that it's another driver. Some info Occurence: It seems pretty random so far, haven't noticed any kind of pattern I tried: Windows memory diagnostic (went smoothly at 1066mhz) As I said, it was still happening on my HDD, so when I bought the revodrive I install a new OS on there and still got the error, I believed it happened and I had no drivers installed at that point (not 100% sure) Change the following registry value to 1 (true): HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager \MemoryManagement\ClearPageFileAtShutdown Tried to lower even more ram clock Made sure ram timing was set to recommended by manufacturer Verified if motherboard was in good physical condition (yes and its brand new) There is one thing to note, when I got the new motherboard, I installed the new drivers WITHOUT formatting and the I removed the motherboard drivers that I could remove from the control panel (pretty much the first things that have been installed). Could this cause an issue even ON THE OTHER drive (revodrive). Hopefully someone can help me, I am getting tired of this, spending so much money and cannot get this to work correctly. If you need any other information let me know, thank you!

• fax server farm architechture

  - by Brian Postow

  I'm not sure this is the right forum for this, but it's not Stackoverflow so... I'm trying to figure out an architecture to solve the following problem, maybe someone here can help: I have a T1 with 23 fax lines coming into the building. I have a computer (Macintosh XServe) running Hylafax. If I had one POTS line, I'd be done. However, I have no idea how to get the T1 into the Mac... Options I've considered: some sort of PCI T1-modem (Does that exist?) Splitting the T1 into 23 POTS lines and then connecting 23 analog modems to the mac, either via an external modem bank (Do they still make those?) or via some sort of external PCI bank, which will allow me to use more than 2 4-port modem cards. Either the T1 or the split POTS lines going into some intermediate device and then transfering the images over IP, or USB to the mac. Really, any other option I can come up with This has GOT to be a problem that someone has already solved, right?

• "The directory name is invalid" when trying to install drivers in Windows 7 via Device Manager

  - by Luke

  First off, this computer is not mine, it's a customer's system. Having said that... The hard drive was moved to a new motherboard, CPU, RAM combo, and booted up fine. Customer puts in driver CD, drivers won't load. He brings it into me. Under Device Manager for Windows 7 x64, I see lots of PCI to PCI bridge, one SMBus Controller, and about 20 Unknown Devices. Greeeeeat... So I start with the SMBus driver directly from the Asus website for the motherboard (P8H77-M Pro). If I install from the setup program, it tells me to reboot, then it starts the install. It gets half way through the setup, then fails (An unknown error occurred. Setup will exit). When I try to point to the folder from Device Manager, it starts copying files for the driver, even presents me with the proper name of the device, but says that an error has occurred there as well: The directory name is invalid. Doing some Googling, I saw that many people had this issue with Vista. K, Vista and 7 are similar, maybe the solutions are the same... But they aren't. I tried: Copying the entire driver folder and setup utility to the Program Files folder and running it / selecting it in DM Downloading another set of drivers in case this one is corrupt Disabling UAC Deleting and recreating the %WINDIR%\TEMP folder Removing all references to previous hardware that I could find, even in Device Manager's hidden mode So far, nothing has worked. A wipe and reload will be out of the question

• Something very strange with network

  - by Rodnower

  Hello, I have Windows 7 and I have very strange thing with my network. Some time I was connected through wireless router and my IP was 192.168.2.103, router's IP was 192.168.2.1 and some other IP was 192.168.2.100. The last I get from page "active DHCP clients" of web interface of the router and from "wireless clients" I may to see that 192.168.2.100 not (!) belong to my MAC address. Router build by EDimax. So after that I disabled wireless function of the router and restarted it. In this time I had not ping to 192.168.2.1. Also I had not any other connection, not wireless nor cable, but (!) I still had ping to 192.168.2.100 and I not understand what this voodoo is...

• lm-sensors - always returns 32 degrees (celsius) for temperature

  - by mopoke

  On my VIA EPIA motherboard (using VIA VT8231 ISA bridge), I get strange output for the lm-sensors temperature reading. It always returns 32 degrees (celsius). I have previously had correct output for temperature (my munin graphs show temperatures typically in the range of 50 to 60 degrees. I've tried uninstalling (and purging) the lm-sensors package, have re-run sensors-detect a number of times and rebooted but nothing seems to change the output. I am running Ubuntu Karmic Koala (9.10). Anyone got any bright ideas on what I might have missed? uname -a: Linux george 2.6.31-16-386 #53-Ubuntu SMP Tue Dec 8 06:39:34 UTC 2009 i686 GNU/Linux cpuinfo: processor : 0 vendor_id : CentaurHauls cpu family : 6 model : 7 model name : VIA Samuel 2 stepping : 3 cpu MHz : 399.000 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de tsc msr cx8 mtrr pge mmx 3dnow up bogomips : 800.04 clflush size : 32 power management: lspci: 00:00.0 Host bridge: VIA Technologies, Inc.

• My Linux desktop sees my HDMI-connected monitor, but my monitor says "No signal"

  - by hrunting

  I have a Gigabyte H55M-UD2H motherboard and an Acer S271HL monitor. When I connect the monitor to the motherboard via VGA, signal works perfectly. When I connect the monitor via HDMI, the system "sees" the connection, but the monitor receives no signal (the monitor shows a blue box which reads "No Signal" and then the monitor goes into power-saving state). Some fun facts about this: if I hook a different monitor to this box via HDMI, the monitor receives the output without issue (same computer/motherboard, same cable, different monitor) if I connect a different computer to the monitor via HDMI, the monitor receives the output without issue (different computer, same cable, same monitor) no signal is received whether in the OS or in the BIOS there are no BIOS options for controlling video output other than for selection of onboard vs. PCI/PCI-E-based video card (the system has no dedicated video card installed) The box is running Linux, so I have the output of xrandr which shows the connection and the monitor modes detected via DDC: ~$ xrandr --prop Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP1 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on HDMI2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 598mm x 336mm EDID: 00ffffffffffff000472ca028d128022 1c160103803c2278ca7b45a4554aa227 0b5054bfef80714f8140818081c08100 9500b300d1c0023a801871382d40582c 450056502100001e000000fd00384c1f 5311000a202020202020000000fc0053 323731484c0a202020202020000000ff 004c55573044303130383531300a01e5 020324f14f0102030405060790111213 1415161f230907078301000067030c00 1000382d023a801871382d40582c4500 56502100001f011d8018711c1620582c 250056502100009f011d007251d01e20 6e28550056502100001e8c0ad08a20e0 2d10103e960056502100001800000000 000000000000000000000000000000de Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on 1920x1080 60.0*+ 50.0 25.0 30.0 1680x1050 59.9 1680x945 60.0 1400x1050 74.9 59.9 1600x900 60.0 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1366x768 60.0 1360x768 60.0 1280x800 74.9 59.9 1152x864 75.0 1280x768 74.9 60.0 1280x720 50.0 60.0 1440x576 25.0 1024x768 75.1 70.1 60.0 1440x480 30.0 1024x576 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 720x576 50.0 848x480 60.0 720x480 59.9 640x480 72.8 75.0 66.7 60.0 59.9 720x400 70.1 HDMI3 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP2 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP3 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on How do I get this monitor to recognize the output from this HDMI socket?

• Integrated Graphics went kaput, can I switch to dedicated graphics if I can't get into the BIOS

  - by Om Nom Nom

  I have an 8 year old computer (Pentium 4 1.6 GHz, 256 MB DDR RAM) which is not turning on (it beeps for 10 seconds and then goes off). Nothing appears on the screen, so I can't get into the BIOS. A computer repair person listened to the beeping pattern and told me that its because of the integrated graphics on the motherboard is defective. It's an ASUS P4S333-VM motherboard and the graphics solution is SiS 650. He tried putting in a PCI graphics card expecting that the computer will use that instead and ignore the integrated graphics, but apparently older computers don't switch automatically to the dedicated graphics card; it needs to be changed from the BIOS. But, I can't get inside the BIOS settings as I already said. I am told that the only option now is to replace the motherboard (which is not feasible since it's very old now). So, is there any way to make the computer use the PCI graphics card? IIRC, the motherboard also has an AGP port, but I think that it will also need to be selected from the BIOS?

• ESX 4.0 space: DASD, NAS, or ?

  - by thormj

  I put together an ESX box for better management, but its performance is a WTF item; I'm a noob at dealing with ESX, so I'm looking for a laundry-list of reading material to help me straighten this out so I can go back to .NET programming. Current storage system: We're running Raid5+Hotspare (8x500 GB spindles) on a PERC6i on a Dell 2910. Due to ESX limitatios, the PERC is showing the storage as 1x2TB + 1x800GB "partitions." I'm not sure of the setup's configuration (stride / stripe / ???) at all. Our Applications We have a SBS server as well as a minor (2x50 GB, but growing at 10GB/month) database server... Our application that lives on the database VM is CPU and I/O insense; it's a database churning excercise mixed in with a lot of computation on the data (fixing that performance is what I'm supposed to be working on)... Perfomance Issue When I do a backup, restore, or worse (copy a backup from 1 vm to another to move it to the QA VM), the entire system slows to a crawl (even "unrelated" VMs). I originally thought a DASD situation would be quite good since you had PCI-x bandwidth, but the systemwide slowdown is killing productivity. Questions What should I do to make an intelligent decision about NAS vs RAID vs SAN vs DASD? Are there sweet spots/ugly spots in the storage setup? Can you use a SSD PCI-X card in ESX for the tempdb? Good/Bad idea? Is there any way to "share" some image in a copy-on-write fashion? Most of the "Backup-Copy-Restore" is to "put a clean image on the dev boxes"; if I could have them "share" the master image, the "big copy" (2x50 GB) would only need to be done once per week instead of once per dev per week...[runtime performance isn't a concern with the dev boxes, but the backup/copy/restore kills production, SBS, and everything else on the box]

• Triple-monitor set-up (2 unique, 1 cloned): Can a VGA splitter be used on one output of a dual-head

  - by stakx

  Background: I'm currently researching hardware components for some kind of information terminal we're building. This application of ours makes use of three output screens: (1) A touch screen where all user input is made; (2) A regular LCD monitor where the requested information is being displayed; and (3) A projector which displays exactly the same signal as screen (2) does. (All screens will run at the same resolution of 1024x768 btw.) Now I figured that using a dual-head video card would be sufficient, let's say a Matrox P690 low-profile PCI card. This would involve having a Y cable connected to the graphics card itself, then two DVI-to-VGA adapters at each end of the Y cable, and then having a VGA splitter on one of the VGA outputs. The following shows the setup in question: 0--1---------2-> VGA (DSUB-15) \ \ ----2-3---------> VGA (DSUB-15) \ \ -----------------> VGA (DSUB-15) 0: graphics card (LFH60 jack) 1: LFH60 to DVI-I dual monitor Y cable 2: DVI-to-VGA adapters 3: VGA splitter cable Question(s): Will this work? I'm particularly concerned about the following points: Can a low-profile PCI video card output a signal which is strong enough for three monitors (even if it's a dual-head card)? Does the combination of so many adapters and splitter cables work? (The LFH-to-DVI cable comes with the video card) Will the VGA splitter cable degrade the signal on the output screen & projector significantly? (If so, would a USB-powered splitter cable remedy this problem?) I can't possibly expect anyone to answer all those questions, but any input is appreciated.

• AMD Fusion GPU passthrough to KVM or Xen

  - by BigChief

  Has anyone successfully gotten a passthrough working with the GPU portion of AMD's Fusion APUs (the E-350 is my target) on top of a Linux hypervisor? IE, I want to dedicate the GPU to one VM only, excluding all other VMs as well as the host. I know PCI passthrough can work with patches / kernel rebuilds for Xen and KVM. However, since the GPU is on the same chip, I don't know if the host OS will see it as PCI. I know there are a number of tangential issues here, such as: Poor Fusion drivers in Linux at the moment Unsuccessful patching efforts seem common VT-d / IOMMU is required and (from my reading) is supported on the APU, but the motherboard may not offer it KVM doesn't appear to support primary graphics cards, only secondary graphics cards (described here) However, I'd like to hear from anyone who has messed with this, even failed attempts. Fedora + KVM is my preferred virtualization platform but I'm willing to change that if it makes a difference. EDIT: The goal is to do this for a Windows 7 guest (I know it's asking a lot). Regardless, just assume this is HVM, not PV.

• Minimum specs needed to run 1080p HD movies?

  - by Wesley

  Hi all, I was wondering how low you could go with hardware that would still be able to smoothly run HD movies. My current plan is around $215 CAD w/o a hard drive: Intel Pentium 4 @ 3.2 GHz - 1GB DDR/SDRAM - 512MB X1600 Pro AGP - 350W PSU - ECS P4VXASD2+ - Bluray/DVD-RW drive. As for the hard drive, could I just get a 7200RPM IDE HDD? Also, I'm planning on installing XP Pro SP3, unless Ubuntu somehow has an advantage. I'm not wanting this to be a media center only computer... just want it to be a normal computer with just enough oomph to play HD movies. Thanks in advance. EDIT1: Forgot to mention that the Bluray/DVD-RW drive is SATA, but I was planning on getting an SATA-IDE adapter or a PCI card with SATA. EDIT2: Oh yes... if I get a PCI card with SATA, would you then recommend I use an SATA hard drive as well? That would leave all the IDE ports on the motherboard unused... is that a good idea?

• Quad channel memory and compatibility

  - by balteo

  My motherboard has quad channel memory compatibility. There are 8 memory slots in all: 4 slots are black the other 4 slots are white. I currently have 4 memory modules of 1 GB each in the 4 white slots. That leaves me with 4 free memory slots. My question is: can I put 4 memory modules of 2 GB each in the 4 remaining slots or do I have to use modules of 1 GB all over?

• Tri-head linux system with Xmonad: is it possible to have HW acceleration

  - by progo

  What means there exists to have three monitors, all controlled by Xmonad and have hardware 3D acceleration as well? I had the pleasure of using three monitors earlier this year, and while Xmonad and Xinerama handle three monitors easily, I had to throw in an extra display driver, and also let go of Nvidia's own TwinView (which is a hack on Xinerama). This left me with no HW acceleration and some flickering as double buffering wouldn't work with certain applications. However, the three monitors handle so beautifully that I had hard time coming back to two. I understand the easiest way to achieve HW-accelerated tri-head combo is to split into two Xorgs. I wouldn't be able to switch windows between the Xorgs, so I'm not really into this solution. What's more, having a cheap and old PCI card along with even slightly better PCIe seemed to slow things down. Even if I occasionally disabled the third monitor from Xorg configure, I couldn't get HW acceleration to work. Only after I physically disconnected the old PCI card, I could get the games back in business. Would a Matrox Dual/Tri-head2go and a powerful Nvidia GPU do the trick? I understand Xmonad can be configured to "believe" that a "single" (as Dualhead2Go will merge) 3360x1050 display is actually two different ones? So that Xmonad's Mod-w and Mod-e would work properly there.

• Network card very slow, only on Windows

  - by J Penguin

  This only happens to 1 of my machine, and only when booting into Windows 7. No matter what network card I put in, Windows would default its mode to 10Mbps full duplex. Transfer speed is approximately 1 MB/s. If I set it to 100Mbps, the transfer drops to 100-200K/s. If I set it to 1000Mbps, the connection is lost completely. I've tried swapping in different cards, both PCI-E and PCI. I'v etried update the windows, I've tried reinstalling the drivers... On this very same machine, if I boot into Fedora, it can use the card at its full capacity 1000Mbps transfering 80+ MB/s And all the cards work just fine when plugging into other machines on the same network. I'm very curious. What could be the reason for this? The only different software that this machine has is virtual box with a VPN emulator, but disabling that VPN doesn't seem to do anything. I would like to get this fixed, hopefully, without reinstalling windows _< Will that be possible?

• NVIDIA Tesla K20C in Dell PowerEdge R720xd --- power cables

  - by CptSupermrkt

  I am trying to put an NVIDIA Tesla K20C into a Dell PowerEdge R720xd. I'm having a bit of trouble understanding the power requirements of the card. First, here is a picture of two pages of the same manual, which seems contradictory to me. One page says only a single connector is required, while the next page says both are required. The entire manual for the card can be found here: http://www.nvidia.com/content/PDF/kepler/Tesla-K20-Active-BD-06499-001-v02.pdf Here is an photo taken of the power connections on the card: And here is a photo of where those connectors need to go, onto the PCI-E riser of the r720xd: Neither the R720xd NOR the GPU came with the necessary cables. And given what appears to be a contradiction in the GPU manual (above), I'm not even sure at this point what we actually need. I have searched high and low online for things like 2x6 pin PCI-E to 8 pin male-to-male and so on, and for the life of me cannot find what we need. In case anyone needs it, the owner's manual of the R720xd can be found here: ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r720xd_Owner%27s%20Manual_en-us.pdf The relevant page is page 68, which clearly indicates that the 8-pin female port on the riser card is for a GPU. The bottom line question: exactly what power cables do we need to buy, and where can we find them?

• Memory modules not running at rated speeds.

  - by Wesley

  Hi all, I'm having some odd memory issues with my build. Here are my specs right now: QDI Superb 4 motherboard Intel Pentium 4 Northwood 2.4GHz (512KB L2, 533MHz FSB) 3x 256MB PC2100 DDR266 RAM 16MB NVIDIA TNT2 Pro AGP Seagate 80GB IDE HDD Generic USB 2.0 PCI Generic Modem PCI Bestec 250W PSU To be even more specific, here are the current brands and models of each module: Kingston KVR266X64C25/256 Samsung PC2100U-25331-Z SMART SM5643285D4N0CHM0H Supposedly, they are all PC2100 266MHz modules with a latency of 2.5. Looking in Speccy, the Kingston module is somehow running at a speed of PC2300 ~284MHz. I've never overclocked RAM at all as I don't know how to. However, when I first started the computer, I had the SMART module in place first and then reset the BIOS settings, including the integrated overclocking options. However, this still doesn't explain why the Kingston module runs at a higher speed than the SMART and Samsung module. Why is it like this? On a side note, where could I find the motherboard manual for the QDI Superb 4? Thanks in advance.

• Managing disk in a VM

  - by dst

  I'm replacing my two old rack servers with a new one that has plenty of power to take over the functionality my current servers. The server is a 4U rack mount with 16 3.5" SAS drive bays, two 2.5" bays, a Xeon E3-1230v2 CPU and 32GB of ECC RAM. My issue is the following. I would like to have a FreeBSD file server with ZFS managing disks. However, I need other VMs for e.g. a shell/git server, mail server etc. I'm wondering how to deal with the following issues: I want ZFS to fully manage the disks, so I'm not using any hardware RAID. Should I pass the SAS controller directly to the FreeBSD system as passthrough PCI? I want to maximize the reliability of the setup. On what disks should I install the hypervsor and keep server system disks? For (2) I have the option of having a RAID setup on the SAS controller and using that as system disk to store the hypervisor as well as VM images. However, this makes PCI passthrough to the file server impossible. Another option is using the two 2.5" bays. In terms of reliability how are SSDs compared to e.g. WD RE4 disks? Would it make sense to have two SSDs in software RAID as boot disks for the hypervisor or should I just go with e.g. WD RE4 disks in a software RAID setup. I also need to think about where to store the mails for the mail server, but this could be done over NFS between the VMs. BTW, this is for home use, so the load is not really that big. What I'm looking for is best practices for splitting up a server.

• Display with intel integrated graphics, bitcoin mine with Radeon 6950

  - by karategeek6

  I'm on Ubuntu Linux 11.04 64 bit. I have an intel i5 with integrated graphics and a Radeon 6950, with one monitor. I would like to run my graphics on the integrated card, and run bitcoin mining on the 6950. I have bitcoin mining working when I use the 6950 for both display and mining. Every time I try and and use the integrated graphics instead, OpenCL doesn't recognize my 6950. Using aticonfig --initial when using the integrated graphics for display breaks things. So I used the xorg.conf it created as a basis and tried to manually edit it. I really don't know what I'm doing, though. My last attempt is given below. The graphics ran off the integrated card, but the 6950 wasn't recognized. Any help would be greatly appreciated! xorg.conf: #Section "ServerLayout" # Identifier "Intel Layout" # Screen "Default Screen" # Identifier "aticonfig Layout" # Screen "aticonfig-Screen[0]-0" # Screen 0 "aticonfig-Screen[0]-0" 0 0 #EndSection Section "Module" Load "glx" EndSection # Intel Section "Device" Identifier "Intel Integrated Graphics" Driver "intel" BusID "PCI:0:2:0" EndSection Section "Monitor" Identifier "Default Monitor" Option "VendorName" "Monitor Vendor" Option "ModelName" "Monitor Name" Option "DPMS" "true" EndSection Section "Screen" Identifier "Default Screen" Device "Intel Integrated Graphics" Monitor "Default Monitor" DefaultDepth 24 EndSection # ATI Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection Section "Monitor" Identifier "aticonfig-Monitor[0]-0" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "aticonfig-Monitor[0]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

• XenServer 5.5 running WHS.. trying to add local or network printer/scanner/copier

  - by ProstheticHead

  Hi guys. Just wondering if anyone has prior experience in sharing a multifunction printer across a (mostly windows) network? My situation at the minute is complicated.. I DID have the printer attached directly to a Windows Home Server box and was able to scan to a share and print across the network from my other computers. Compatibility problems have forced me to virtualize WHS on XenServer 5.5... This is actually quite useful because I can now run other things on the same box, but the problem is that now WHS doesn't get direct hardware access so it doesn't see a USB attached PSC... Grrrr! So now I have a choice to make. I've read somewhere that I can buy an add in PCI USB controller and somehow set up a passthrough to one VM at a time. To me, this sound complicated but if it's likely to work reliably I'd prefer this method. I've read about another approach, which I'm not sure about either, but I guess sounds plausible. A Network USB server, (NOT a print server) that can somehow make a USB port accessible across a network. My worry here is that it likely needs some kind of 3rd party software to work.. so not ideal. If there are any other methods you can suggest I'd be happy to hear them... I need your help guys. I'm also in the market for a PCI express SATA controller, nothing flashy, just need up to 8 ports, JBOD and 100% compatability.. Any suggestions? Regards Kevin

• GUI interfaces to ATI card behave weirdly out of the box and after updates.

  - by jdk

  My Lenovo W500 came with an ATI Mobility FireGL V5700 and both the Catalyst control center software and Vista display manager display four monitors. What's really annoying is the behaviour. My two active displays (laptop display + my external monitor) are always #s 3 and 4 respectively which doesn't make sense. This is out of the box. Additionally dragging & dropping is jumpy and displays #1 and 2 (always inactive because they don't exist to the software) are often preventing me from dragging #3 and 4 to the rightmost side. They also auto-snap to weird positions and certain sensible positions like position one directly over top of the other are not possible. The exact same annoyances are present when using the Windows Display manager too. In other words the interface is crap and I'm looking for a fix that's not wishing I had gone with nVidia instead. I've updated drivers, and Catalyst control centre. Have latest Windows and AMD/ATI updates. Any thoughts?

• VMWare ESXi 5 - Expanded RAID 5 array - cannot access datastore

  - by Dayton Brown

  I'm using VMWare ESXi 5 and had a 2 TB RAID 5 setup on an HP DL360 with a P400i RAID card. I added two more 1 TB drives and using the SmartStart ACU, added the drives and expanded the logical disk. Now after booting back to ESXi, the server boots, but lists no available persistent storage. I've rescanned multiple times to no avail: the Datastore doesn't show up. I booted to GParted and the 1.8TB partition shows up, but it shows as unknown. Anyone have any good ideas? EDIT: Final Solution So after much gnashing of teeth, it was fairly simple to solve. I purchased an eSata 2 TB external drive and a PCI eSata card for my server. I then used Clonezilla to image the current partitions to my new external drive. You have to check "don't check drive sizes" in advanced mode, otherwise it will yell at you for have a smaller drive. For some reason my PCI card wouldn't boot on my HP server, so I hooked the drive up to another desktop I had, booted to VMWare, and copied the vmdk's to another drive. I'm going to blow out the RAID config and then create 1.5TB logical drives.

• Windows Server 2008 - RAID 5 Fails on Reboot

  - by Adam

  Hey, I've got an install of Windows Server 2008 Enterprise. It's running software RAID-5 with five disks. The disks were originally formatted under Windows Server 2003, but came up fine once I installed Windows Server 2008. The issue I'm having is that every time I reboot the server, the RAID comes up with a "Failed Redundancy" - the data stays available. I have 4 disks on a PCI SATA controller, and one of the disks connected to the motherboard's on-board SATA ports. (The other on-board port has the system disk connected.) I was having Disk #4 fail consistently, so I tried swapping the cables on the controller end. I swapped the on-board RAID disk with one on the PCI controller. Same issue now, expect with disk #1. Once the system's up, I can reactivate the RAID, it will resync for a while, then go to "Healthy", and will stay that way for an indefinite amount of time - until I reboot. As soon as I reboot, the disk drops again. I've ruled out disk + cable with the recabling. I don't believe it would be the controller as it seems to work fine most of the time - only failing on reboot, and the other port on the same controller connects the system disk - which is clearly working. I did look in the event log, but didn't see anything particularly relevant (although I didn't know what I was looking for - just looked for anything with a "Warning" or "Error" symbol that looked disk-related :)). I'm not particularly familiar with RAID on Windows, does anyone have any idea why this might be doing this? Any idea how to fix it? Any suggestions appreciated! -- Adam
