Cannot boot from CDROM nor get to OK prompt SunV210

Server need to have the OS reinstalled (5.10 SPARC) and I cannot get it to the OK prompt. I also do not have the ALOM password and I've tried several different methods to zero out the NVRAM but to no avail. There is no ALOM battery that I can pull. I'm connecting via Cutecom (like minicom) and serial cable from my Linux box.

I would sincerely appreciate any and all suggestions.

If you can boot from the hard drive(s) you should be able to use scadm to reset ALOM and eeprom to set OBP.

Have you tried to boot without hard drive(s) installed? If so- what happened?

Forgot to add, I don't have any passwords to the accounts. Going to try booting w/out hard drives.

How can I use scadm without a valid username/password and no access to the ALOM?

---------- Post updated at 09:27 AM ---------- Previous update was at 09:11 AM ----------

Pulled the hard drives and booted. Nothing came of it. Below is the result of me trying to enter a break (~#). scadm won't work at this level; I've tried.

Code:
Please login: ~#
Please Enter password: **


Invalid login.
Please login: 

Serial line login timeout, returns to console stream.

Enter #. to return to ALOM.

can you elaborate on the cdrom thing? when you power down the system, put in a cd and power up, you can't get it to boot off cd? i take it the system auto-boots from disk?

That's exactly it. Frustrating.

OK, past the ALOM password issue. I sat there and guessed passwords for an hour and found it Smilie

Now I'm at the sc prompt and enter poweron so that I can get to console and the ok prompt. I can't get past it attempting to poweron and looping as seen below:
