I'm afraid your out of luck :( THe Prom passwd is there to stay. Only you might
consider trying the following, even though I doubt it would work, but it's worth a try...
ok setenv security-mode none
or you can do so from the eeprom command in the OS, see man eeprom(1M) for further details.
But as I said, I doubt it'll work because of what's written in the "OpenBoot 2.x Command
Reference Manual" for Solaris 2.5:
"CAUTION - It is important to remember your security password. If you forget
this password, you cannot use your system; you will have to call Sun's customer
support service to make your machine bootable again."

Need to have sun replace the prom!
Pry the old PROM off of the board, and install a new one, is my guess :-)
Once it's set, my understanding is that it is SET.

Yeah, Sun will do it for a fee. If you can get it from the people the
IPX came from you should be okay. Otherwise, if you paid for it, send it

1. Get the password from the prior owner.
2. Get a disk for a Sun4c system (Sparc 1, 1+, 2, IPX or IPC) and take the
existing disk out, and make the new disk your boot disk. Boot off it, and using
the EEPROM command you should be able to set:

You need to have the eeprom replaced
From: "Bill Fenwick" <email@example.com>
Uh, no. Somebody has set the IPX to its secure prom mode, and unfortunately
you need the password to change the mode (or do much of anything else). The
only thing you can do is replace the prom chips.

If you can bootup from disk, issue the command:

If you can boot any solaris OS on it, you can then run the "eeprom"
command and change the password. Otherwise you'll have to pull the
eeprom out of it (to flush the memory) and then put it back in.

Replace the boot prom.
There is a way but it requires SUN's assistance. I have heard of prom passwords
and fixes but have never done one, from what I have heard it is quite the pain.
From: "Fiamingo, Frank" <FiamingF@strsoh.org>
The PROM security settings can be:
none - no password set
command - ask for a password for anything other than the normal boot
full - ask for a password for everything
In full mode you either need to know the password, or replace/reset the
In command mode you can proceed with the normal boot from disk without a
If you know the root password you can then use "eeprom security-password="
to reset the PROM password.
If you don't know the root password you could remove
the disk and configure it in another machine, and then put it back.
If you think you need to replace or reset the PROM, check out Mark
Henderson's NVRAM FAQ before
