I didnt think that LinuxBIOS would help me but was worth a shot. What do you mean that the SuperIO chip should be easy to get going?
Linux bios supports a SMC chip with numbers that are very close to the numbers on your board. Typically that means very little difference between the chips so a quick check with the datasheet would show you what if any tweaks you needed to make to get serial IO. Thats the first step in linuxbios support.
Its all pretty much mute though since in order to do that you would need to replace your OTP bios chip with something you can re-program.
I have confirmed that it is working fine and is powered up, but the bios doesnt even try to boot from any devices connected to it.
Acording to the posts I saw the bios has no int19 support so they really didn't want it to boot from any disks.
If it can't be made to netboot easily then your probally better off just chunking it. The RE effort for anything else will be quite large.
