[coreboot] jarrell_rom_jumper.c ( I think I found it )

  I opened the node up to check out the jumper situation and I did find some thing odd although I don't know what relevance it holds.
  The BIOS is a 4 meg chip, it has 2 partitions and linux bios is installed on the second partition.  Moving the jumper from 2-3 to 1-2 position revealed that factory bios is still on the first partition.  Trying to chain load etherboot failed with a lockup and bios post was complaining about "missing microcode for cpus".  Among other things.  I did get it to boot PXE on a Perceus cluster, but then ran out of time.  I am hoping that re-flashing with an intel BIOS will correct the missing microcode and other issues that linux bios left behind. (Clearing the cmos did not help). I am also curious to see if flashrom picks up correctly now.  I will keep you all updated.

A jumper would be surprising. Intel stopped doing jumpers on many
boards before this board was made.
