Could be.
I assumed LVDS on

- I'll have to check e.g. the voltage levels on pins 8/18 (5 or 3.3V)
and 19/20 (12 V). Is there a typical default pinout for LPC?

could use anything.
I've seen other applications which used 20 pin connectors for GPIO purposes

I know that the BIOS can be programmed easily onboard since there's a
Windows software around to reprogram it.
Is there any kind of de-assembler within coreboot that would help to
find out what the current BIOS versions do?
Thanks,
