In that case, I feel that many people will start building open
source
bioses for a limited set of mobos. They will provide the software to
burn the bios into the mobo's eeprom or will even sell mobo's which
them modify and install their own bios prom on. I think nature abhors
vaccum.
The required information for almost all X86 devices is not available.
You can't build an open firmware for most x86 platforms from public
information.
