K8N Neo2 Driver Problem with PCI Bridge.

Question

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.

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.
