I have run into a problem with a workstation. The computer will not accept input from the keyboard. I have tried 3 keyboards, so that rules out a problem with the keyboard itself. When I boot, the lights flash, and the number lock light goes on so it seems the keyboard is receiving from the computer. I cannot even get into the bios. I tried connecting the keyboard using a ps/2 – serial adapter, but that didn’t work either. Is there any work around for this? My only thought was to purchase a USB keyboard, but I’m not even sure that will work.
