Sun Sunfire V100 LOM and OBP (firmware) password reset

I bought a surplus-store Sun Sunfire V100 server (with CD) for which I don't know either the LOM or Firmware/OBP passwords. I do *not* have a Sun keyboard or any other Sun hardware. When I connect to the console, LOMlite prompts me for a password.

Using the J13 method, I managed to get passed the LOMlite password and get a lom> prompt and boot the system up. When I get to the > prompt (restricted monitor prompt), typing "boot" attempts a network boot. Trying probe-all, boot cdrom -s, or anything else gets me to a "Firmware Password:" prompt. I can't boot the internal drive either.

I setup a JumpStart server to try to install Solaris 10 over the network, however I can't assign the machine an IP or Hostname because I don't know the OBP firmware password, so the V100 never finds it.

The internal drive has a Solaris 10 install which I do not know the passwords for. I booted it a few times before I tried resetting the NVRAM (which made network boot the prioirty).

I know that if I can reach a solaris prompt I can reset both the LOM and the Firmware (obp) passwords and be on my way. How can I reset or bypass the firmware password so I may install reinstall Solaris?

I appreciate all responses.
