EPIA going immediately to fallback image?

[Al Hooton]

	Mainboard: EPIA 800.

	Building LB appears to go well, using these steps (my Options.lb and
Config.lb are listed at the end of this note):

- cd <stuff>/targets
- ./buildtarget via/epia
- cd via/epia/epia
- make

	The build appears to go without a hitch.  At that point I write
targets/via/epia/epia/linuxbios.rom to my flash part, and boot the
board, only to be greeted with this:

LinuxBIOS-1.1.7.0Fallback Wed Jan 19 16:11:07 PST 2005 starting...
vt8601 init starting
Slot 00 is SDRAM 04000000 bytes x2
Slot 01 is empty
Slot 02 is empty
Slot 03 is empty
vt8601 done

	Can somebody let me know what might cause it to immediately go to the
fallback image, instead of the normal image that has my filo payload in
it?

	My Options.lb and Config.lb are below -- I didn't include the build
output because it's so big, but if it would help anyone I can send it
along.

	Thanks for any and all help!
