I've tried to boot from ROM SHELL, but there is no such way, the
permissions are'nt enought to edit, even to view the file /etc/passwd and
/etc/passwd.master, i read an article about password recovery of SGI IRIX
6.5, you need the CD Install, which i dont have, ive try to crack the
password (according to John the ripper docs), not successfull, debian wont
boot from CD, and they said Debian MIPS dont support SGI  O2, Is it true?

Sayang naman yung SGI O2, anybody has the CD Installer of SGI IRIX 6.5
