Hello,

Please see if anybody can help me, because I've googleing for days with no result.

I've got a PC with Windows Vista with PS2 keyboard port. The PS2 port is not working anymore in Windows nor at boot time, but it works fine with a Linux Live CD.

I'm using a USB keyboard in Windows, but my problem is that I can't access BIOS setup because USB keyboards doesn't work till I start Windows.

I would have to set the option "USB legacy support" on BIOS setup, but I can't enter at BIOS setup, because the PS2 keyboard doesn't work.

It cannot be a hardware problem, because the keyboard works with linux, and I think it cannot be a Windows driver problem, because the keyboard doesn't work at boot time.

Hello,

Try this 1

Turn off your PC --> Remove the power cord --> Open the cabinet --> Remove

the CMOS battery for 20mins. After the specific time, place the CMOS battery back

properly ---> Connect the power cord --> Now Turn ON your PC.

Good Luck
Thank you

I don't understand how this worked...at all....but it did. Was working on my nephews computer. The mouse and keyboard work during boot to get into the bios, etc, but where disabled at the start screen on XP (I know....old and EOL). I pulled their hard drive and placed it in a totally different "known good" machine to rule out hardware and the same thing happened. I removed the cmos battery for several minutes and put it back and voila! It worked! I can't explain that.

Rebooting your PC has the exact same affect.
