Shuttle SB61G2:GPF after AGP installed

[b26440510]

I've had this system running for years. Today I installed the first AGP card in the system. Now the system GPFs after boot. This is not a BSOD. It GPFs after the BIOS does its stuff (Boot from CD?, Verifying DMI pool) and before the OS' bootloader runs.

I have tried resetting the BIOS via the JP1 jumper but still GPFs.

Here's the GPF (note it's copied by hand and may contain typos)

Got it working again.

Swapped out the SATA drive with the old SATA drive (replaced it about 4 weeks ago). System boots fine with that one. Put the new drive back in, booted to DOS from floppy. All of my FAT32 partitions are showing up but my boot.ini file contents are corrupted. I reformatted C:, copied my boot files back then ran fixmbr and fixboot.

This is the same fix I have to do occasionally because sometimes when I boot it reports "No OS Found" and my C: partition will be corrupted. I've tried different SATA cables, updated the BIOS, etc. but still have the problem now and then (that's why the new drive). I've never seen it do a GPF like this though.
