since EDO/FPM don't have a SPD eeprom there's no need trying to get any 
data out of it :)
size and internal organisation detection is done by a simple algorithm. 
i hope i'll have a sample of it ready later. it'll feature the ram init 
and detection of the Intel 430FX chipset and will have lots of comments 
:) the rest should be a bit of datasheet surfing and register adapting 
(more or less).
