I'm trying to boot a PC (with a clean, formatted hard drive) that doesn't have any PS/2 ports with a USB keyboard and mouse. They are detected when turning on the computer, but the keyboard does not respond at any prompts. What is odd is that I am able to enter the BIOS by pressing F1, but after that it doesn't respond to anything I type on the keyboard. I have tried this keyboard on my Windows XP machine and it works fine. Any suggestions or comments would be appreciated.
