The problem lies in the fact that the SOYO BIOS doesn't properly initialize the
MTRR stuff (or not at all :).
We've had similar problems about a year ago with this SoYo thingy, it didn't
happen is we stripped the memory to 512 ...
(at the lilo prompt: linux mem=512M)
Anyway, if you add this line to the rc.sysinit right after the /proc gets
mounted, you'll won't have the get-a-mobo-and-feel-like-you've-got-a-386
sensation wandering around in the back of your head:
echo "disable=0" > /proc/mtrr
echo "base=0x0 size=0x40000000 type=write-back" > /proc/mtrr
HTH,

BTW: you should read /usr/src/linux/Documentation/mtrr.txt for more info on the
"echo [some_txt] >/proc/mtrr" syntax
