It looks like I just lost my wireless capabilities, and Windows along with it. One of little blocks in the wireless USB device came off so it doesn't work anymore. I tried taping it into place but that only worked for a microsecond before replacing the plastic cover jarred it out of place. I removed it and restarted Windows for the umpteenth time, but now all I get is a blue screen of death saying it can't access a device and that I need to run Windows setup again. I've tried loading it into safe mode, but that doesn't help because almost every device on the system is listed two or three times so I have no idea what to do from there, not to mention none of the devices (e.g. the CD drive or Ethernet card) work from safe mode.
So, I'm stuck in Linux now. I don't have an official Windows 98 [SE] CD, even though I have the license to own one. I'm not sure what happened to my Windows CD.
If anyone happens to have a spare version of Windows laying around I'd be very grateful. Update: Nevermind. I looked up the problem file on Rob's mac and it turns out uninstalling ZoneAlarm fixed the problem. I assume it had something to do with the USB device not working.
