Another thing that can be done is reseting the bios by software.
all you have to do is write a byte to address 0x30h and another on 
to 0x31h this resets the bios.

I can get hold of the source code in pascal if I look around my old 
college day floppies. 

I last tested that on a mix of PIII an equivalent non intel 
motherboards and it was still runing.

take care.
