Not a question but a tip to share.

We ordered a few Sun Blade 100s and I started to test-install the first
one. We bought memory upgrades (Sun Memory!) for 1 Gig per machine. I
moved the 128 Mb Dimm to slot DIMM2 and put 2 512 Mb Dimms in slot DIMM0
and DIMM1.

After a while the machine would reboot, with the following reasons:

I tested and swapped but it turns out the Dimms need to be in their socket
very firmly (apply some pressure when seating them).

So far it's running stable now.
