Do you have a DIMM in the first slot (J0201)?

There are several ways to clear a PROM password.  If you can boot the
system up and log in as root, the eeprom command from within the OS can be
used to disable PROM security.

I suggest the following references:

The second contains my method to remove a PROM password without buying a
new NVRAM chip or hot-swapping any parts.  Buy one (20 cent) socket and
you're set.
