Dear Markus,

this is a challenging approach! I probably don't have 2 left hands but I
have really never worked with BIOS before :-). So I need more information:
where can I find ChipSelect signal on the motherboard/BIOS socket?

I assume that I can skip the whole procedure if I do a 'hot swap' of BIOS
chips on the motherboard? I am planning to use Linux to re-program the BIOS
so I assume that I can do the 'hot swap' of the chip with motherboard
powered on? or is it not advisable approach?
