[ixp1200] GigaMAC diagnostic problems...

[Austen McDonald]

	Im talking about the diagnostics test from Intel---it comes w/ the
system. Unless you've removed the diagnostics from the flashROM you should
be able to set jumpers 12 & 26 both to 2-3 and restart it. But, if you
really want the microcode, its in the BoardSupport/Diagnostics directory
of the installation.
