I have used GA-6OXE board which has dualbios.
As you know, there's no jumper for dualbios.
Instead, there's some logic to check and take over to other bios.
The problem is we don't know how this logic works..
As for my experience,
I programmed linuxbios on the first (master) rom. It seems to work just about a few seconds.
I got normal linuxbios messages from the serial. However, after then, control is transferred to
second (slave) rom.
At first, i suspect that linuxbios image that i built have some problems. However,
when I programmed slave rom with the same linuxbios image which was used
for master rom, I can boot linux. That means linuxbios itself has no problem.
To say briefly about the whole process.
at first, linuxbios on master rom start working. but after 5 second,
control is transferred to slave rom. so linuxbios on slave rom start.
After then, all others works fine if the linuxbios is correctly built.
Strange, isn't it?
I guess dualbios logic check kind of checksum of the master rom. therefore it
think linuxbios as incorrect bios.
Anyway, I decided not to use gigabit board because I can't find the way
to boot linuxbios on the master rom socket. You can boot linux, if you
program linuxbios on slave rom. However you should pay 5 second until contol is
transferred to slave rom by dualbios logic.
