Hey all,
I'm trying to figure out how to do a build a rom which contains *only* the normal image and not the fallback. For my purposes I don't believe I need a fallback image since I'm burning my images to a ROM emulator. The rom in question is only 512k and I need to fit 'other stuff' in there as well.
Appreciate it :) -San

You have to do it the other way around. The fallback image is mandatory, the normal image is optional.

There really isn't any good documentation on doing this. If you will write up your eventual config and what changes you had to make I'll see that it gets up in the wiki.
As Stefan said the "Fallback" image is what you want. Its the first image booted. If I remember correctly you can modify your buildrom statement in your Config.lb to keep from copying the normal image into the generated rom.
So changing
buildrom ./linuxbios.rom ROM_SIZE "normal" "fallback"
to
buildrom ./linuxbios.rom ROM_SIZE "fallback"
should only include the "fallback" image in the final ROM.
However this dosn't mean it will work. *grin* The normal+fallback scheme is wired in pretty deep. You may have to go change the startup files a bit to achieve exactly what you want.
The Intel XE7501DEVKIT code that I checked in earlier this week uses a single image. Have a look at the target and mainboard config files.
