Resetting/bypassing P/OS password on DEC Pro 3xx series?

Anyone recall what the procedure is for resetting or bypassing the 
password on P/OS?

I *know* I was able to find this out before (in 2008 or so) because I 
did it on another Pro 350 I have, but I cannot for the life of me find 
anyplace that documents the procedure (the FAQ 
(http://www.deccomputer.info/2012/05) has no useful suggestions).

I recall it required booting from a special floppy that had a few 
filesystem tools that'd allow replacing the password file; I'm sure I 
still have the disk image but I have no idea which one it is.  I guess I 
should have saved the instructions somewhere (or maybe I did and I 
simply can't find them!).  I must be getting old.

I have a new Pro 350 in my possession which has a PC compatibility card; 
I'd like to see if the hard drive contains software for it (or anything 
else interesting) before I wipe it...

Thanks,
Josh
