| I have put Phoenix ROM's in a compaq before only to get a gate A20 handler
| error and then this system hangs (I suspect AMI ROM's will do the same thing).

I suppose my offer was a tiny bit ambiguous. I meant he could have
my _programs_ so he could modify his own BIOS. Nobody would
seriously expect I meant moving a BIOS between motherboards, surely?
