Ron and James, thanks for clueing me in on the fallback image stuff.  I'm still not quite doing something right though, it seems.

My config files are below.  I based these on the samples in mainboard/supermicro/p4dpe.  The fallback image is 81k and contains the etherboot payload...this doesn't seem right to me but I don't know what else to do.  If I don't specify the etherboot payload, it tries to use vmlinux which is much, much bigger.

So I run the config script on both files, then go to the fallback/ and primary/ directories and run make, and I get a primary romimage of 458752 bytes and a fallback image of 81920 bytes.  That doesn't seem right.  What am I doing wrong?  Oh and though I was doubtful, I did do a "cat primary/romimage fallback/romimage > finalimage" and burned the final image. 

Also, from the looks of the makeprocess my two image files are basically the same binary stuff but one has a lot of null padding.  They both contain the eepro100 elf image and linuxbios.rom...

Anyone see what is wrong with this picture?
