Yep, my favorite consoles are OpenBoot and SRM (but I don't have much
experience with the "real" lights and switches type). Don't like the
Open Firmware/CHRP types as much, not nearly as user-friendly.
One thing to remember for Sun equipment that you're not sure about is
that some OBP commands work only when "diag-switch?" is set true (for
instance probe-pci, which will quietly do nothing if diag-switch? is
set false). Once you're done you need to set it back false if you want
quick booting, though.
Does anyone know if there's a way to speed up the tests on an E3k?
Neither the diag variables (that I know of) nor the keyswitch position
seem to affect self-test time (putting the key in "diag" displays where
it's at, though). So far in "modern" class Sun H/W (Ultra) I have a
U10/440/SCSI/Creator3d, U2/2x200/Creator3d, and a E3k/2x250/TGX (which
I might be getting a brace of 400MHz boards for). I'm trying to decide
whether to keep all three. The E3k (in common with my HP 9000/G70 and
RS/6000 3CT) takes forever on the self-tests, which might just mean
that I need to plan ahead when I want to use it (isn't it amazing how
long ~7minutes can seem?).
