Hi
> Has anyone found anything about the "second" plcc socket?
I was planning to investigate this. But currently i am a little short on free
time. So if you are patient or if you have some multimeter you can check if
the pins from bios chip are connected to the equivalent free contacts.
I have taken already an look at the dualbios stuff from gigabyte. It seems as
both bios chips should contain the same bios (at least partly) and some
software logic determines which chip it activates for booting. Well it's
patented so there "should" be some information available but so far i haven't
found the corresponding patent filings (are they public or only available
with the ever involved "bling" when it comes these patents ?).
Then there has to be some logic which decides to boot from which chip. But if
s.o. can dig up the filings we probably know more?
Then it would be nice if someone from the list could point out which flash
chips might be compatible with the free contacts. Also there has been some
remarks on this list that the inner contacts may be some kind of rom contacts
and the outer are flash contacts.
So before bricking your mainboard just try to dig up the above information?
And probably we will find a way to enable an dual boot between the original
bios and the linuxbios, which would be quite neat.
