Everyone,
I've tested i945 code on i946 board and I can hear tuck tuck on its buzzard, got FC 00 on serial...an repeat tuck tuck and nothing on serial....
I'm thinking on diassembling the code on i946 bios, I've downloaded a copy on my computer as a *.bin.
and make a copy on another chip W39V040FCPZ....originaly from W39V040FB..
