make error when building rom

[robinsmidsrod]

The romburning software might require a file that is exactly X number of bytes to work. You can usually make this happen by padding the file with NULL bytes. If you look at the rom files downloadable from Broadcom, maybe they are all the same size. Try to pad the ipxe rom file null bytes until you reach the same size. I believe there is a tutorial on how to do this on the main ipxe site, or possibly buried somewhere on the old etherboot wiki.
