Well I'm using the gpl_vsa_lx_102.bin from MJones, turned off VGA option
roms, Seabios Stable as the payload, and an extracted bios using the script
from the wiki.[
There is a very old thread pertaining to this that I had a look through but
couldn't really explain any of the problems (or why no fixes have been
pushed up). [
I admit that I don't understand alot of the details of the boot diagnostics,
but if anyone cares to have a look, heres the bootlog for what happens with
the above setup. http://pastebin.com/jNtuEyV7
Thanks for your quick responses.
