USB Keyboard not working during booting. Please read details

I was using a PS/2 keyboard which worked fine, but isn’t working anymore. Now, I am using a USB keyboard. My USB keyboard doesn’t work during booting and starts working only after the OS (Win XP) is loaded. It seems like the default setting for USB keyboard support during booting is disabled. So, how can I enable USB support in BIOS when I can’t hit the “Delete” button to enter BIOS? Is there any registry entry which I can modify to enable USB keyboard support during booting?
Please don’t ask me to purchase another PS/2 keyboard!!!
Thanks in advance for all answers
Answer #1
are you connecting it in front or back of PC ?
you try all ports in back ?
do the lights on the KB flicker during boot ?
will the PC boot without the KB connected ?
or do you get a no KB error ?
if you get the error try connecting the KB at this point and hit the “enter setup” key
with the KB connected try the “reset CMOS” jumper on the mobo

nope
this is a before windows loads problem so no registry solution the lights flickering seem to indicate it’s being found you have a USB mouse connected as well ? try disconnecting it
if you have any other USB devices connected disconnect those as well
if you still have the non-working PS2 KB try connecting both KB’s while booting
you could also try taking the motherboard battery out for a � hour or so to try to reset the bios

i did exactly what you said…i disconnected 2 USB devices before switching on my pc…
surprisingly the F2 key worked and i entered the BIOS but the arrow keys didn’t work…
then i changed the port and the arrow keys worked fine…
i enabled the legacy usb support…
now my usb keyboard works absolutely fine….
