well this thread has wandered and fragmented before I saw it.

I have a Sun Ultra 5 running in my basement. It took me a little bit of
work to keep it running.

One problem with these platforms is that they have a battery powered NVRAM
chip in them, that will give out after a several years. (Sort of like a
If they die, the boot fails.
Good news is that the replacement parts are available. Here's a FAQ
I got one from Digikey for about $20.

A tip: I found if I left the system powered up for several days, that the
NVRAM would charge up enough to boot ... sometimes.

wrt: boot process
- Scrounge around on the Sun website in the docs area, you need to find the
detailed documentation on the boot process and commands.
- There is a extended diagnostic mode that you can evoke with the right key
combinations at power-up.
- It will display running POST diagnostics while booting to the screen or a
serial terminal. You can also get it to leave a failure code in the
various lights on the keyboard. (get that keyboard hooked up!) You need
the docs to decode the indication.

Solaris 9 and Companion software CDs are availible from Sun for FREE on
their website. There are also sunfreeware sites out there.
