- Apparently somebody on your system chose to set the PROM password.
- This password is *not* the same as the root password. If nobody
- there knows it, you have no choice but to remove the NVRAM
- chip (on the backplane, it is an 8 pin DIP), so you can get
- to the PROM monitor. Then you can boot a kernel over the net,
- boot the miniroot. Unfortunately, due to some miscommunication,
- it is very difficult to disassemble the system such that you
- can remove the NVRAM, power the system on, stop in the PROM monitor,
- and then re-insert the NVRAM (without turning the power off), so you
- can clear the password.
-
- Alternatively, if you have another Indigo with the same type of
- graphics, you can temporarily borrow the root drive from that
- system (which presumably will boot with no problem). Once you
- have a kernel booted, you can use the command
- /etc/nvram passwd ""
- to clear the PROM password (you can't set it this way, but you
- can clear it). If you are doing it from the miniroot, do
- /root/etc/nvram passwd ""
