I attached a log with seabios set up on debug level 6, is this the highest one? because 7 and 8 made compilation fail.
You could try the latest SeaBIOS.
Yours: Start bios (version 0.4.2-20091228_104949-pcq.gap.upv.es)
I'm not sure how old 0.4.2 is, but the one I just tried is 0.5.1 pre-0.5.1-20091228_125433-orangutan
Thanks, Myles
