hmmm....this is very annoying. dang it.
I ended up reinstalling XP. I tried to do a Repair, but that didn't help. I made 3 different DOS partitions, C:, for XP, then D:, and E:, for games and other programs. So I reinstalled XP onto my C: drive, everything was working fine. then now, as I get done installing a program off the CD ROM drive, which is F:, I take out the CD, put in a different one, and the drive just dissapears!!! F: is no longer listed, and its not listed in Device Manager. WTF is happening? I've NEVER seen that happen before, on XP, let alone 95/98/2000/ME before....I'm going to reboot, see if that helps.
