This computer has XP pro, Asus P5WD2 motherboard, Amibios v0709. A while back when I built this computer I had a PS/2 keyboard. While using that keyboard I thought it would be nice to use a KVM switch so I could plug in a Slackware box I also have. Everything worked great. When I decided not to use the 2nd box I unplugged the KVM and at one point I bought a USB keyboard. After using this USB keyboard I decided to start using the KVM switch again. Now my PC won't recognize the PS/2 keyboard. I checked in the Bios and found nothing for the enabling a PS/2 keyboard. In fact I cant even get into the bios with a PS/2 keyboard. Only the USB keyboard is recognized. I've updated the bios, disabled quick boot, and even tried using bios default settings...still nothing. I know if I reformat and reinstall the operating system I can get the PS/2 plug to work but I don't want to go thru that hassle. Has anyone seen a problem like this?
