[LinuxBIOS] Which svn revision works with VIA EPIA M-II? - coreboot

9 Nov 2007


      Hi guys,
I finally have spare ROM chips to play with and I am ready to put
LinuxBIOS on them - I have problems with compiling the beast, however.
I have checkied out the latest revision from SVN and here's what I'm
getting when trying to compile:

Here's my Config.lb:

end
#buildrom ./linuxbios.rom ROM_SIZE "normal" "fallback"

--------------- CUT --------------------
I have commented out the normal build because I want to prepend
original VGA BIOS from the board to LinuxBIOS and I guess the fallback
one is the right one to use (at least according to LinuxBIOS
documentation (documentation/HOWTO/EPIA-M-howto). This file also
states how to get the VGA bios:
dd if=/dev/mem of=/video.bios.bin \
                   bs=1 count=65536 skip=790528
while Confirmed working SVN revisions at
http://www.linuxbios.org/index.php/Confirmed_working_svn_revisions
says something different:
dd if=/dev/mem of=video.bios.bin.4 bs=65536 count=1 skip=12
(I have checked that generated files differ)
Big thanks,
