K7n2 L - pci to pci bridge problem (unsolveable ressource-conflict)

hallo.
if i enable graphics-adapter(agp - hercules 4500), no pci-devices are shown. it's a e/a conflict between the "pci to pci bridge" and the "nvidianforce2 agp host to pci bridge".
i tried to fix it by convert the acpi-pc into a standard-pc and as this doesnt work i installed win2k with the f5-key --> choosing standard-pc.
nothing work! i still can't solve the conflict.
the ressources are still not adjustable in device-manager.
when i disable the "pci to pci bridge" a window pop up and tell me that new hardware (graphics-adapter) is found.
thnx for any sugestions in advance!
mike
ps: i tried moving the pci-cards and upgraded bios to 5.1

i like to thank u all, ppl. i phoned the support and they told me that they dont know anything about incompatibilities and i should check the "Compatibility Test Report" (thnx moot). did that and found no hercules-board in it! damn, what can i do.. i changed the mb against a A7N8X deluxe. guess what.. the new board doesnt even boot with the hercules-card attached. put in my old g-force2 and the mainboard works. now i put the hercules in my 2nd pc and bought a asus g-force 4 - 8x - board and all works fine. i'm pleased because i now have the mcp-T sound onboard i wanted first.
last thing to say:
the msi-telephon-support in germany sucks!
thnx again and best regards
mike

Standard PCI to PCI bridge no longer working after BIOS update

Hey everyone,
Before I get into the details of what is probably the most frustrating computer problem I have ever faced I would first like to say hello because this is my first post and I give you my system specs.
Windows 7 ultimate x64
GA-M61PME-S2P (rev 1.0) MOBO
2x 120GB Mushkin SSD @3.5gbps Raid 0
AMD Phenom II x4 @2.2 GHZ (Old processor that I replaced)
AMD Phenom II 1090T x6 @ 3.2GHZ (New processor that replaced the Phenom x4)
MSI Cyclone GTX 550 TI OC (Nvidia)
8 Gigs 800mhz DDR2 RAM (Computer Bay)
I have had a GA-M61PME-S2P (rev 1.0) board for several years now and have never had any problems. I recently bought a brand new AMD phenom II x6 1090T processor because it was listed as being supported by my board. The BIOS version that I had installed before purchasing this processor (version F5) was unable to recognize my new processor and boot so I had to update to the latest version (version F7b). After flashing my BIOS with the new version I was able to boot and my computer recognized my processor with the correct name and clock speeds. Unfortunately it now no longer recognizes one of my standard PCI to PCI bridges. Of the two standard PCI to PCI bridges listed in device manager one of them has a yellow exclamation point and reads "error code 35 firmware does not contain enough info to configure this device". I have tried everything I can think of but just cant seem to get my processor and graphics card to work under the same BIOS version. I will now list every step I have taken;
1.) I have re-flashed several times between versions F5 and F7b but always get the same results
2.) I have used Driver cleaner in safe mode to wipe all drivers and then double checked programs and features to make sure nothing was still installed.
3.) I have installed all drivers for the board from Gigabytes website, although when I try to install the VGA driver i get an error saying that no device could be found that supports the driver.
4.) I once again wiped everything in safe mode and then found the latest chipset drivers for nvidia Nforce from NVidia's site but got the same results.
5.) I tried downloading the F7b BIOS from some random website just in case the file from Gigabyte was somehow broken but this did not change anything. (I know that's generally a bad idea but I am desperate)
6.) I uninstalled the problem standard PCI to PCI bridge in device manager and restarted my computer but got the same results.
7.) I tried installing my graphics card drivers from MSI but got an error saying that no supported hardware could be found.
8.) I tried installing a number of different versions of the Nvidia graphics card drivers for my series but kept getting that same error message
9.) I downloaded the Graphics card detector program that NVidia provides on their site but it told me that it could not detect my graphics card.
10.) I tried Flashing my BIOS to the F6 version for the rev 1.3 board but this turned out to be a huge mistake because my computer would no longer post after this and I had to use a FAT32 flash drive and the q-flash utility to bring it back to life.
11.) I checked over and over and over again that my BIOS settings were right and nothing was setup to only use on-board graphics.
12.) I tried downloading a driver that was supposedly for the PCI to PCI bridge but im fairly sure this was just a trojan because the install did not complete and I found tons of fun plugins installed afterwards (I reformatted shortly after this).
13.) I made sure that my new processor was plugged in and that my BIOS was version F7b and then completely wiped my hard drive and re-installed windows 7 ultimate x64 but got the same results.
14.) I made a bootable DOS flash drive and tried updating my Graphics card BIOS but found that I already have the latest version.
What I don't understand is that my graphics card works perfectly with BIOS version F5 and my processor works perfectly with BIOS version F7b but under no circumstance do they both work at the same time. It may be worth noting that with version F7b installed I am still able to use my graphics card ( my Monitor is plugged into it via DVI) It just gives me the error under device manager and I can not install any drivers.
If anyone out there can help me I will be insanely grateful and will refer to you from then on as the master of all things MSI. I'm at my wits end, If you need any further info just ask and I will provide.

Ah ok I was afraid you were going to say that. I will take this to gigabyte then but just so I know, This PCI to PCI bridge problem couldn't have anything to do with my MSI graphics card BIOS somehow not being compatible with the Gigabyte BIOS?
-Thank you!

K8N Neo2 Driver Problem with PCI Bridge.

I updated the Bios on this machine last night to 1.04 from 1.03
K8N - Neo2
AMD 3500+ Retail Kit with Cooler
Antec True430W 3.3v/28A 5v/36A 12v/26A
OCZ 2X512 EL DDR400 PC 3200 Plat Ed Dual Channel
Seagate Barracuda 120g 7200 rpm SATA
TSST Corp DVD-ROM TS-H
ATI Radeon 9000 64mb AGP
Windows XP SP2
It started acting funny several hours after the update of the Bios, this AM it spontaneously rebooted and when it came up there was an error message about a damaged or corrupt Windows system file and suggested inserting the Windows Disk, which was done and then the system booted into windows. But the found new hardware came up and wanted driver for the PCI bridge, which I wasn't sure where it was so I let it complete without finding it and this is the error when I go to control panel/system/hardware/device mgr
Where do I get this driver? Is it on the driver disk that came with the motherboard? I don't remember having to install a driver for the PCI bridge.
thanks

OK I thought I'd post the resolution to my problem.
After my initial posts the machine not only became unstable but it wouldn't boot into windows saying there was a corrupt Windows System File.
1. It occured to me that when I downloaded the new bios and applied it that I had failed to customize the DRAM settings in the bios. This was important because when I was building the machine I couldn't get Windows XP to install it always pooped out someplace early in the install. At the time I was using default DRAM settings. But I came here and read through the forum and found a sticky at the top of the forum that had settings for a number of different memory sticks including mine. So I went back and updated my bios with those setting. Voila everything was cool and I was able to load windows and move forward. But I forgot that, and I attribute the instability of the system to that, wheter or not it was why the system eventually corrupted system board dirvers I don't know. But I did change that, as the system would boot but just not boot windows.
2. Next, I decided to attempt to repair my windows install. However first since I had already applied SP2, and my Install disk was just the plain retail without any Service Packs. I decided to make a new bootable install disk with SP2 slipstreamed into it so when I repaired I wouldn't have to reapply SP2. Here's the method that I used.
http://www.helpwithwindows.com/WindowsXP/winxp-sp2-bootcd.html
3. Utilized the windows repair feature of windows setup.
4. That worked my computer now booted into windows and I didn't lose data or configurations....whew!!
5. I still how ever was stuck with the original problem that started this thread..rats!! I thought SP2 would fix that.
6. I tried several times to get XP to update the driver, but I couldn't. I even tried to select the driver from the list that is one of the optioins when you are updating drivers. I found some but I wasn't sure which one that had PCI bridge in it was the right one. But the fact that when I was looking at the list of mfg only Compaq and NVidia were available. So a light bulb went off and opened up MSI Live and looked at what was available in drivers, and sure enought there was a NVida driver. So I figured I have nothing to lose.
7. Next I downloaded the latest NVida nForce3 system driverfrom MSI and applied.
8. Bingo that worked, no more yellow ?'s in my hardware list.
Machine working fine now. Still don't know if failing to insert the proper DRAM stuff caused this but it all started with the new bios so I am assuming it had some part.

Windows 7 - Pci-to-Pci Bridge (Error: Code 10) - PCI Video Card

Before I state my issues I will list what I'm running and what I'm trying to accomplish.
I'm running Windows 7 Enterprise 64-bit edition, not the Beta or RC. I have 3 video cards in my possession (listed below).
- (PCIe) Evga GTX260
- (PCI) Evga 9400GT
- (PCI) Evga Fx5500
Out of those 3 cards I only use the GTX260 and the 9400GT. I had to 'retire' the Fx5500 because the latest WHQL (certified) drivers only provide support as far down as the "6 series" Nvidia cards. Unfortunately the Fx5500 is a "5 series" and falls below that line. I have already tried to use the GTX260 and Fx5500 in previous versions of Windows (XP and Vista), but there is no way to download and install two separate drivers for two of the same make of video card - you'll get nothing but errors. There is the option of going to a place like guru3d.com and downloading a custom supported driver that covers both the GTX260 and Fx5500, but the drivers are not certified and lack support. Therefore, I purchased and now use the 9400GT which is covered under the drivers for the GTX260 and eliminates the need for messing around with custom drivers. Also, the 9400GT has a better graphics processor and more memory than the Fx5500, so it was time to upgrade anyway.
Now that you have some background info here is my issue Whenever I install the 9400GT I get a second 'pci-to-pci bridge' entry (the other entry has no errors) that shows up under 'System Devices' in the Device Manager. The second pci-to-pci bridge entry has a yellow triangle with an exclamation mark on it that refers to a problem. When you check the properties of this device it more or less says that Windows has detected a problem (Error Code 10). The GTX260 still works and even shows up under the 'Display Adapters' as a GTX260, but no entry for the 9400GT exists. I have tried the 9400GT in both PCI slots and each time it does the same thing. If I pull out the GTX260 and ONLY run the 9400GT, I still get the pci-to-pci bridge issue, BUT I do get a picture and can boot into Windows 7 without a hitch. When I do this there is still nothing listed under the 'Display Adapters' as a 9400GT or even a VGA compatible device.
After messing around with this for 10 hours (yes, I said 10 hours) I decided to dig out my retired PCI video card (the Fx5500). When I installed this card I had no 2nd pci-to-pci bridge entry appear under 'System Devices', and the one that was listed had no yellow triangle or error codes. I then checked under 'Display Adapters' and Windows 7 had recognized it as a VGA compatible device and was asking for drivers.
I have now concluded that there is definitely no issue with the motherboard or any of my hardware (including video cards). At first EVGA Support and I had suspected that the motherboard may be bad because of all of the pre-diagnostic steps I had taken during my 10 hour ordeal. I'm not going to list everything I did because it would literally take 3 hours to type it all in. Just believe me when I say that I have tried most things including but not limited to the latest bios updates (flashed 4 times and completely reset to ensure accuracy), custom IRQ management, entire OS re-installation X2, multiple/latest chipset drivers installed, multiple/latest video drivers installed, memtest testing, complete hardware teardown and re-build (adding one device at a time), and MUCH more. The only thing I did not try was installing a different OS other than Windows 7 64-bit to see if I could replicate the issue. This is a waste of time though because lets say that I install Windows XP Pro and the 9400GT doesn't have this issue... Well, that's great, but who gives a damn about XP Pro when I have been using it for the last 9 years and when I have a full version of Windows 7 that I want to use? I'm certainly not going to run XP Pro over Windows 7 just to use this PCI video card. Second, if I install XP Pro and it still gives me the same pci-to-pci bridge error then again, I've only wasted more time because if its not going to work in either OS then Im sure as hell not going to leave XP Pro installed when I can use Windows 7.
Thanks,

Maybe stupid question now but has your posting anything to do with Toshiba and Toshiba notebooks?

Try extracting the files from the 4-in-1's to a folder, then try updating the drivers for your PCI bridge, pointing it to the folder you extracted the files into, when asked. It should load a driver for the South Bridge chip.

Just what was going on when this error message started showing up? Usually this type of error happens after a OS reload or when new hardware is added. If neither of these things were done, then probably a hardware failure. There is a modem installed according to the spec page: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00874655&cc=us&dlc=en&lang=en&lc=en&product=337...
If that is not being used, then try removing it. Maybe just lucky enough that is the problem. Most other items are integrated on the motherboard

Pci to pci bridge error code 35 after installing my new graphics card

hello everyone
first of all i am not sure if in the right section of the forum to post this...if not i am sorry.
well about my problem...i ve bought this new graphics card msi geforce gt430 and a new psu which is 580 watt and yesterday i installed em both.and then i turned on my pc. the thing is windows cant detect my grsphics card.there is this yellow exclamation mark on pci standard pci to pci bridge in device manager menu.i tried uninstalling pci to pci bridges and rebooting my pc.it didnt help.i also tried updating every single driver again nothing changed.i also have one of the latest bios so i dont think it should be related to bios.i have no idea how to fix this.i am a little bit ignorant when it comes to pc hardware.i can use all the help i can get.
thanks for your helps in advance.
astinwald

Yup, wrong part of the forum.
Sven will move it next time he's here.
Pci2pci is a motherboard thing but could interfere with gfx detection.
I know you said you'd reinstalled all drivers but...
Did you get the latest drivers for your motherboard?
If that doesn't fix it I guess the next step would be a complete OS reinstall...

Code 12 on [VIA PCI to PCI Bridge Controller]

Hi,
I am having an issue while setting up a new pc with the following setup:
MotherBoard: MSI P4M900M3
CPU: Pentium Dual Core e2180
Memory: 2 * 1Gb Kingston DDR2 667
Harddisk: Hitachi SATA 320Gb Harddisk
OS: Windows Professional (upgrade to SP3)
Using the build-in video and audio card provided in the motherboard.
After I installed the OS, i find a yellow exclamation mark in [Device Manager] -> [System Devices] -> [VIA PCI to PCI Bridge Controller] (there are 2 of these entries with the same problem) indicating the problem is :
This device cannot find enough free resources that it can use (code 12).
If you want to use this device, you will need to disable one of the other devices on this system.
I have tried removing the 2 entries and let windows detect it automatically but the same problem still show up.
I have only 1 harddisk, 1 dvd drive and 1 floppy drive connected to the motherboard so i wasn't expecting such conflicts to show up.
Please help.

Have you tried to delete them, and let's windows to re-detect them?
Have you done >>Clear CMOS Guide<<?
What mainboard you have? {P4M900M3-F or P4M900M3-L}

MXI-4 PXI-PCI bridge

I tried to set MXI-4cd it but I have a message that says components are already set (NI-VISA...).
But I have basically a problem with MAX Explorer which does not recognize the PXI system.
In my PC, the first PCI-slot is devoted to a NI PCI-6052E card.
The second one is devoted to the PCI8331 card.
I think the problem comes from the communication between the PCI-8331 in the PCI-slot and the PXI-8331 in the PXI-1031 chassis (bridge).
But this one doesn't seem to be recognized.
In MAX, there's just a device PCI-6052E in Traditional NI-DAQ-device or NI-DAQmx-device.
So if this card is not recognized, then the PXI system (that I powered on) cannot be recognized as well (PXI-1031 and its modules PXI-GPIB, PXI-7344, PXI-4204).
The communication must be wrong maybe because of the PCI-8331 which is not read from the PC? I wonder if the PCI-8331 in the 2nd slot at the moment should be set in the first slot instead of the PCI-6052E???
I tried the VISA option in MAX (show ALL PXI-PCI devices accessible to VISA instead of ONLY) and then to restart the system.
I tried as well to identify PXI as external PC or other (I can't load any PXI-1031 from CD: not a valid file), and to show PXI-buses: but PCI-6052E is shown?
Note: basically I think I can remove the PCI-6052E board (which we shouldn't use) since the Data acquisition can be down by the PXI-4204???
Thanks for quick answer.
Best regards

Hello,
Check if your MXI-4 board show up correctly in the Windows Device Manager.
MXI-4 boards contain two distinct PCI functions onboard and will have two separate listings in the Windows Device Manager (WDM).
The first function will show up in the WDM listed under System devices as a PCI standard PCI-to-PCI bridge.
The second function listing in the WDM will show up as a MXI-4 Connection Monitor when the correct MXI-4 driver is installed.
If the MXI-4 software is not installed, the PCI-to-PCI function will still be detected and work correctly, but the MXI-4 Connection Monitor will be detected as an unknown device.
If MAX indicates that the MXI-4 connection has timed out, the MXI-4 card did not detect that it was connected to another MXI-4 card at power-up
time. This can occur if the host chassis is turned on before the expansion chassis, or if the MXI-4 cable is not plugged in properly. (see screnshot attached).
Hpoe this helps.

DKA790GX PCI to PCI Bridge issue

Hello,
I get a DKA790GX Platinum with vista ultimate x64 (EN/FR) and 8GB RAM + Phenom 9950 BE.
I decided to build soft Raid 5 with sil3132 chipset via e-sata support connected to a raid box with 4 sata 2 drive
I installed this additional card on a PCI-E slot
Now I obtain an unknown device PCI to PCI Bridge that I could not update anyway. I browse some forum about related issues and many users upgrade bios to resolve conflict
So I updated my bios to version 1.3. Operation has successfully completed but my problem still remain
Th silicon device is recognized I can browse and build Raid group but, I stuck to 18MB/s that's far away from 3Gb.
I think this bottlekneck is due to bad PCI brigde

PCI-to-PCI bridge confilct under Win2000

I tried to install the PXI-1000B chassis under Win2000 through MXI-3 interface without success. From the device manager I found that there is a yellow question mark on a standard PCI-to-PCI bridge. It reports that there is a conflict in IO-port range assignment which was pre-occupied with the other device. But I can not find the device. There is not any other device which uses the same IO-port area. And from the advice of knowledge base, I have edited the registry of my video adaptor(NVidia,AGP), but failed to detect the PXI-cards. The MXI-3 optimization works well(It does not report any error and whenever I run it, the LED of the chassis blinks.). But the devices in the chassis do not show in MAX and device manager. I can find
two more PCI-to-PCI bridge from the device manager. One is occupied by the AGP video adaptor(PCI bus 1). The other is on the PCI bus 2. A new PCI-bridge was shown after I inserted MXI-3 card, which was linked to the PCI-brige on bus 2 as subsidary, which reports the conflict. How can I solve this problem? The attachment is MXI3.log after running the optimization software.

Hello Robert,
Thanks for your explanations. I also understood the purpose of the PCI-to-PCI bridge.
I have actually two PXI 1045 chassis used in two similar configurations.
I initially did not see the resource problem when using my first rack equiped with 6 PXI cards (1 MXI link and 5 DAQ cards), since everything looked fine within MAX and I had access to all I/O channels under LabView.
It is when I setup the second chassis fitted with 10 cards that I discovered that cards 7 to 10 had a resource lack. This rack is linked to an identical HP PC as the first configuration.
There was also a resource lack for the NI trigger routing module and one PCI-to-PCI bridge.
The first configuration had the first resource issue conerning trigger module and PCI-to-PCI bridge.
We tried to use the chassis with another old Dell computer running Win2K, and it worked fine. So it is probably not a rack fault.
I guess MXI-4 needs a driver, since it adds these bridges that need I/O memory resources.
We use the last Bios for the HP workstation. I really do not understand why the cards have this resource problem, and how to investigate further.

MS-6508 PCI to PCI Bridge Conflict URGENT!

I have an IBM Intellistation MPro 6850-XX4 that is based on the MS-6508. On installation of WinXP Pro, and using the latest IBM DAE142 BIOS, latest I860 drivers from intel, I get a conflict with the PCI to PCI bridge.
The only thing I have on this computer is a Pinnacle Systems Liquid Chrome 64bit hardware card. With fresh install of XP Pro, and loading the chipset drivers listed above, yeilds this issue. Please advise on what action is necessary to resolve this conflict.
Regards,
Rod Martin

is the msi version but yours is some sort of oem board made for ibm if it uses their bios so i suggest you ask them

ASMedia PCIe to PCI bridge chipsets kill DVB functionality (SOLVED)

This is not so much a question but a forum placement to help others in future search situations.
This can be very important for anyone who uses PCI DVB DTV cards, not PCIe, and have all their hardware and software working but the DVB cards intermittently but very repeatedly no longer respond. Actually any type of PCI card which needs decent PCI throughput can be affected here. All PCIe to PCI bridge chipsets are famous for potential bandwidth limiting but in the case of ASMedia, they are known to be outright faulty:

If you are using VDR, TVHeadend, or MythTV with FFdecsawrapper (open-sasc-ng in the old days) with PCI hardware, and you have an ASMedia chip on the motherboard, such as asm1080 or asm1083, you can patch the kernel to fix this. Below is a patch that works with current 3.10 ARCH and tested with 3.11 ARCH now in testing. The patch is actually a sort of hack because the chips are apparently faulty and the patch changes IRQ polling for the whole IRQ system. I can sometimes notice a bit of weird behaviour here and there in other things but nothing serious. My DTV is however FINALLY rock solid (big sigh):

As I can see you have two wireless interaces, when i see only phy0 with rfkill, it's maybe your hp-wifi that force to disable phy0 interace. I think if you blacklist the driver it might allow phy0 to be enabled.
Please download and install lshw available in the community repo and enter in a terminal :
$ lshw -c network
