Thank you CrazeD,
Sorry, not OS/2, but PS/2 mouse and USB keyboard.
I did manage to get into CMOS and change the boot priority so I could run the XP repair utility. It ran as the MS Support document illustrated, then when the system rebooted, chkdsk ran and moved about 10 dll and sys files. It ran so fast, that I wasn't able to copy them down. Now when it boots, it goes through the POST, system configurations, Windows XP screen, blue screen (no messages) then loops back to the POST.
My plan is to add another hard drive to load windows on to (I was thinking of doing this anyway), then DOS into the existing HD and delete everything but the Documents and Settings Folder so I don't lose my data when I recover. I was also going to switch out the mouse and keyboard for USB wireless anyway - just not now though.
I know there are a million posts about this looping problem, but not a lot of them with clear success stories. Is there an easier way? I'd rather not have to reload all of my software again.
Thanks again for the help,
