Dell Latitude D610 laptop.
Stopped booting into XP with message: "pci.sys is missing or corrupt"
Runs fine with UBCD4WIN32
Hard drive tests good. Has been scanned.
Memory tests good.
pci.sys has been expanded/replaced from Windows CD.
Have read that bad PCI hardware can cause this. But, I really have no notion where to start. I'd much prefer to not take the laptop apart but can do if necessary.
It does appear that half the memory on this MB is on the "other side" .. maybe just under the keyboard.
And, of course, it does boot fine for UBCE4WIN32!! but I notice that there are a lot of drivers missing when one does that. Even so, I did install many of the PCI-related drivers .. the ones I could get to happen online.
