I have a Gateway Bro Essential 866 micro desktop that has NO ps2 ports. Only USB. How can I enter the BIOS/CMOS? I am being prompted to hit F1 to run setup, but it won't respond. Also, I have reset the CMOS jumper and then rebooted, and sure enough the PC will enter the CMOS, but then there is no keyboard to navigate. The "support" at Gateway CAN NOT resolve this issue. They insist that hitting F1 will work. IT DOES NOT. I have tried EVERYTHING! The BIOS is AMIBIOS Version 07.00.xx dated 7/17/00. In the CMOS screen it says BIOS version 0AAVIP01. PLEASE HELP! I'd hate to have to get a new Motherboard for this POS.
