Hardware :: BIOS Detection Of PCIe Bridge
Apr 7, 2011
I spent all day yesterday trying to figure out why the PCIe expansion (bridge) card I bought was not being detected by my BIOS (and ultimately my RHEL5.4 OS). It was not until I actually plugged something into the expansion card that the bridge itself and the expanded PCIe component were detected.
I have tested and re-tested this issue.My question is this: Why must I have a PCIe component connected to the bridge for the BIOS (and OS) to detect the bridge itself (and the connected PCI component) ?

I have fairly new requirement for a second monitor. My main display is running fine using nvidia proprietary drivers.I do have a pcie (probably x16) video card sitting around, but my motherboard only has 1 x16 slot (used by my main display), 2 x1 slots and a few pci slots. From memory, the second video card is an ATI card.Questions:
1. Can I put a PCIE x16 card in a PCIE x1 slot?
2. Would using 1 Nvidia card and 1 ATI cause trouble?

I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.

I bought a Laptop with Sis 771/671 onboard graphic, with a 1440x900 resolution. Since this SIS is not supported by the open suse distribution, I am running it with poor resolution for two years now. Every update of OpenSuse I hope it could be supported now, since I see in the internet that there seem to be solutions for other distributions. However nothing happend yet.
Is there any intension at OpenSuse to do something about it ?

I've searched everywhere I could think of and have been on google for about 4 hours today searching with no luck.Is there anyone out there who can confirm a working PCIe sound card on RHEL4.4 (Linux kernel 2.6.9-42)?The only cards I've found that work on Linux are the Asus Xonar cards and the PCIe version of the Sound Blaster Titanium but they are confirmed for later versions of Linux but I can't modify the alsa drivers or update the version of RHEL.

I am testing a PCI card in a 4-slot bus expansion chassis. I bought the chassis from CoolDrives.com, it appears to be identical to the Startech PEX2PCI4 unit, but was quite a bit cheaper... This device shows up on my lspci output:
05:00.0 PCI bridge: Texas Instruments XIO2000(A)/XIO2200(A) PCI Express-to-PCI Bridge (rev 03)
I think that the following line may also be associated with this device:
06:07.0 PCI bridge: Hint Corp HB6 Universal PCI-PCI bridge (non-transparent mode) (rev 11)
I've installed in the expansion chassis one card, a Linux Media Labs BT484 card. This card works out-of-the-box when installed directly in the system, using the bttv driver. Installed in the expansion chassis, the card still shows up as follows:
07:00.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
07:00.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
07:01.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
[code]....
When the card is installed directly in the motherboard it gets IRQ17 or 18. I suspect that it does not really want IRQ0, but that there is some problem detecting the proper IRQ over the bus expander. One possible approach I am considering is to build a custom version of the driver where I can set the IRQ manually to something else just to get the driver to finish loading, then see what happens when I run the card. This would at least tell me which IRQ the hardware is really using and whether or not the 0 reported is correct or not.

I recently added a new graphics card to my machine. Normally, Centos 5.3 runs without a hitch, but since the new card, boots as far as a kernel panic. Even a rescue or an install disk comes up with a kernel panic.I have tried Centos and Fedora CDs/DVDs.The card is a PCIE Radeon HD 4350.It works fine with XP, btw.Ubuntu and OpenSuse will load from install sources.

I'm wondering if I could put my old DualCore PCIe Board into a Proliant 3000? Why not; I mean, the Array Controller should plug right into the PCI slot on the DualCore board. Of course, I'll have to shoehorn a second power supply into the case for the newer Board, but wouldn't it be a monster! Two 3GHZ Processors, with a 256 MB nVidia graphics card, 1.5 GB of RAM, and 8 Hard Drives! (7, actually, because one of them doesn't work). I'm up late, and I think I'll start working on it right now.

I am unable to access a standard memory pcie card bar registers through my driver on the pcie interface for Zotec H55 ITX motherboard (it includes a built in NVideo engine). This is the following setup:
1. Fedora 14 32 bit pcie scan does see the board (lspci -n show card on pcie bus #2)
2. Configuration register read is good. (pci_read_config_byte())
3. The following driver commands did correctly return bar information: pci_rsource_start(), pci_resource_end(),pci_resource_len()
4. The commands iowrite32() or memcopy_toio() results in no pcie transfers (determined through pcie core probing)
5. The same driver code fully functioned on the Intel DH57JG mini-ITX. (using lspci -n, pcie located on pcie bus #1)
6. Note, it seems that the pcie connector for Zotec is on bus#2, where as Intel MB pcie connector is on bus#1. Note also that the Zotec has a built in NVidia graphics engine.
The following driver code was used. Again, it worked on DH57JG:
pcid.pciaddr_phy_str_bar0 = pci_resource_start(pcid.pcidev,0);
if(pcid.pciaddr_phy_str_bar0 == 0) {
printk(KERN_INFO "fail to get pci start address for Bar0.
");
return -ENODEV; }
pcid.pciaddr_phy_len_bar0 = pci_resource_len(pcid.pcidev,0);
if(pcid.pciaddr_phy_len_bar0 == 0) {
printk(KERN_INFO "fail to get pci end address for Bar0.
"); .....
// testing
for(i=0;i<100;i++)
for(j=0;j<4;j++){
iowrite32(0x13572348,(void *)(pcid.pciaddr_base_bar2+(long unsigned int)(4*j)));
iowrite32(0x12344321,(void *)(pcid.pciaddr_base_bar0));}
i = ioread32((void *)(pcid.pciaddr_base_bar2));
printk(KERN_INFO "pci bar2 reg0=%x
",i); <<<<< FAIL .....

I have been thinking about upgrading my RAID setup from a pair of Intel X25s running the software based RAID included with ubuntu to four Intel X25s running off a PCIe based controller. The controller is an HP P400 which I know works great on ubuntu (I have other machines running it with SAS drives). My desktop has an Intel S5000XVNSATAR mainboard and I have an open PCIe v1.0 8x (physical) slot that is wired 4x. The controller is 8x and will fit fine. How much of a performance hit do you think I will see running this 8x controller in the slot wired 4x with four Intel x25s in a RAID 10? Will I have enough bandwidth with the 4x for those SSD's?

I have a ATI Radeon HD 4000 PCIe card in my Debian system. I got the proprietary ATI drivers working (fglrx) but a kernel upgrade killed that. I was unhappy with this driver due to the very high memory usage. The card works with the non-proprietary drivers but I can only clone my desktop. I want a single desktop on two monitors.
I booted with Ubuntu Lucid and my dual monitor desktop worked out of the box without the proprietary drivers so I thought that I could emulate what Ubuntu does in Debian. But I can't.
My issue is that I don't know whether I am missing a module in the kernel or I need to set up a brand new xorg.conf. Ubuntu doesn't have an xorg.conf to copy. My default Debian doesn't either.
I have messed around with my own xorg.conf and added various drivers eg "ati" and "radeon" but I can't get it to work with a single desktop dual monitor display.

I'm having trouble getting a PCIe device to show up in lspci using pcie hotplug.
After booting the system I load the pciehp module, I then plug-in my PCIe card. After that I do an lspci, but I don't see my PCIe card. When I cold boot with the PCIe card installed the system sees it fine, i.e. it show up in lspci.
Does anyone know of an easy way to figure out if my hardware even supports pcie hotplug?
When I load the hotplug module I just do a modprobe pciehp. Is this all I need to do prior to plugging-in my pcie card?
I will try running pciehp with debugging turn on to see if that gives me any additional info.

I am trying to install a PCIe card for data compression in Linux ubuntu 9.10(karmic Koala). As you can see in the following code although I have the root access I can not get permission to install the device driver.As I have the root access I suppose to get access to install the driver. I checked around and got the procedure from a web siteEnabling root access in unbuntuBasically in almost all linux machines we will be havingroot access for login.but in ubuntu by default that option was not enabled.If u want to have root login in ubuntu then u have to do some changes in ur Ubuntu machinesSteps to follow1.First enter into ubuntu as your user login.2.Then open the terminal and type the command sudo -s,it will ask for root access and type the password.3.Then type passwd root it will ask for new password4.Open terminal and go to the path /etc/gdm/5.Open gdm.conf6.search for AllowRoot=false7.and then change AllowRoot=true8.now restart ur machine9.now u can enjoy with root accessThe funny part is when I search for the file which is gdm.conf in the prescribed location, I can not find it.
Code:
root@faisal-desktop:/home/faisal/Desktop# cd AHA/
root@faisal-desktop:/home/faisal/Desktop/AHA# ls

I have a fresh install of suse 11.0 and there is no 3d acceleration available. If I use the suse repository, which driver do I need to enable 3d accesleration? The video is integrated on the motherboard. The box is an hp pavilion a1130n and amd 3500+ processor. I installed the same suse 11.0 on a dell box with an ati 128 rage and 3d was enabled after the install.

I recently finished a mini-itx machine and everything was working great with a fresh Jessie install. I put in a PCIe wifi card and now the computer won't boot. The power LED is on, the PSU fan is spinning, but I get no display output at all and I don't know how far into the boot process the thing even got. I removed the card and the machine boots fine again.
I only have one PCIe slot so it is my only option, I don't have another PCIe card to try, nor do I have another machine to test the wifi card in. The card is brand new, for what it's worth.

If i install new hardware using a vmguest or physical system How can I detect it.
disk
nic
memory
etc.
In AIX we just run cfgmgr -v. Is there a similar command in Red Hat?
I am guessing a reboot will pick it up if the device drivers are common enough and in the kernel already.
I want to know how to do this dynamically with the system on-line if possible.

I opted to blow away my system (no did not save xorg.conf), and do a clean install of 11.3. Not a big deal to blow it away, nothing lost.
Dell Dimension C521, 3GB RAM, Athlon DualCore
OpenSuse 11.3 x64
Nvidia GeForce 6150LE (on mainboard)
Dell 2048FP 24" Monitor, connected via VGA
When doing the install, all appears to go well. I added the "nomodeset" option after the first boot to avoid the graphics issues. KDE comes up and is in 800x600 mode at 50hz. That is the best resolution it will show. All other options in the configure desktop applet are lower. This monitor was driven at 1900x1200 on the same config with 11.2.
[Code]...
In the nVidia-Settings applet (run as root), it shows the display as "CRT-0". 11.2 showed it as a Dell.

Amarok 2 can search through music collection using ID3v2 tag's 'bpm' field. That would be very nice to retag the entire music collection so I can find the 'mood' of the track I like.However I've not found any beat-detection software that could have helped me. Have you ever used one? CLI, preferably. Also I'm interested if there's anything alike for tagging FLACs with the same 'bpm' field.

I have essentially been raised on Windows so I have no idea how to get DVI to work in Ubuntu. I have a Ubuntu/Vista desktop with an ATI Radeon X1350 graphics card. I can get picture from DVI when I boot into my Vista partition (the computer originally came with Vista and I have a Zune which will not work with Ubuntu ). But the moment I try to use DVI on Ubuntu: I have no picture. The ATI Radeon X1350 Pro is using the open source radeon driver. I know this from the System Testing diagnostic I ran when I finished setting up Ubuntu, the log file mentioned a line: Kernel module: radeon, underneath the section about my graphics card. That is about the limit of my Linux skills for right now, so any thoughts? If you need more information about my system I can comb through that log file which is still saved in my Fire Fox history.
