Why do we use a variable MTRR to map the bios code instead of the fixed ones? I've been trying to integrate a VGA bios alongside the normal and fallback images, but that 2 ^ XIP size requirement is making things very difficult. So far I have only managed to include the VGA bios code blob if I disable the normal image in the config.lb Is there anything preventing me from using the fixed size MTRR descriptors for the bios area instead of a variable one?
@Luc - Are you working on getting a VGA textmode console running on the VIA Epia board? I stumbled on your name on the unicrome project, so if anyone could do it, it'd be you :) In any case I'd be very interested in anything along those lines...
