Thanks, I already have those files. The system has WINNT installed, but can't get past the admin Password. Tried installing fresh copy of WINNT, but it needs a specialized version. Win2000 server install will not work without the correct PROM.
I have the 320/540 recovery cds but in Spanish language. Never tested so I don't know if the recovery is WinNT or 2000. I think the SGI Windows 2000 was an standard OEM cd, nothing special so my recovery must be Win NT. I'll try to make images this week. It also came with drivers and utilities in separate cds.
