[ixp1200] GigaMAC diagnostic problems...

[Heaton, Eric D]

Austen,

Yes, there was a problem with a rev of the diagnostics with causes the
gigabit port tests to fail.  The latest patch for v1.2 (which upgrades the
software to 1.2D.76) fixes this problem.

	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.
