I have an HP desktop that I'd like to switch from PS/2 to USB wireless keyboard. It WILL NOT boot if it doesn't find a ps/2 keyboard. I can install BOTH keyboards and the USB will work, but if I attempt booting with the USB only, it will not boot.

Suggestions? It doesn't boot? Any error messages?

What if you remove all keyboards and try to boot?It FUNCTIONS normally with a ps/2 keyboard or with both of them ATTACHED. When both are attached, both of them function as expected. It just won't boot with a usb attached. When booted with a usb, immediately after the Windows screen, the BSOD is generated because it is searching for a ps/2 and none is found. We have not found a way to prevent the search or load of the ps/2 driver.Hmmmm....I would think it is something to do in the BIOS but I'm not sure.

I would wait until another member comes along and SEE what they conjure up.Carbon is right. You need to go to BIOS, and enable USB keyboard support.Why the switch from PS2 to USB ? ?

The rule of thumb is to use PS2 if it's available...You're right, patio, but what about OP strange problem?Quote from: Broni on August 19, 2008, 06:56:18 PM
