My friend just bought a used computer (Compaq Armada E500 running Win98). When he tried to instal a usb mouse gps he ran into problems and gave me the computer in the hope I can fix it. Since rebooting his computer, I've found he's lost his "D" drive (cd/dvd) from "my computer". If booted in safe mode, device manager shows that the drive exists. However, no amount of uninstalling and reinstalling fixes the problem. Also, have an IRQ conflict on hard disk controller "primary intelR 82371AB/EB IDE controller". Think this is causing the problem, but not sure. Wish I knew what the friend did to cause this! Any suggestions welcome.
