Booting without keyboard

I have a PC with Windows XP Pro installed that I want
to boot without a keyboard or mouse attached, but
when it boots it gives a "keyboard error or no keyboard
present" error. I've gone in to the BIOS settings
(Phoenix Award WorkstationBIOS CMOS Setup Utility)
but I can't see any setting that would fix it.

Anyone got any ideas as to how to fix it??. Is it a
registry setting or a BIOS setting??

I'm not sure that you can do this with that BIOS....I could be wrong though.

Headless booting requires a special BIOS/Mobo I think.

colm is right - it's bios dependant

If you just need to boot it once can u borrow a mouse kb and plug it out after bios check?
alternatively you could buy a kb & mouse dongle
(mimics presence of kb & mouse)

Do you get "No keyboard detected, press Del to enter setup"?
But seriously, I thought Award Bios' had a setting for halt on errors. Could have been in the first setting screen (can't remember name, the on at top left) or advanced Bios features. Something like
Halt on error: (all but keyboard/mouse) (all) (something else)
Then you just select which conditions it should halt on, if any. It's been a while since I had a mobo with Award bios though (BP6, about 4 years ago). Lately they've all been stupid AMI, though my current AMI bios is very usable. If the setting isn't there though you're goosed. Buy a cheep keyboard/mouse and leave them connected.
