Linux cant read the older 5.x XFS system Thus having an unmountable

filesystem was efs; don't think xfs appeared until IRIX 6.X.
In your situation, I'd start an installation from the installation
media, enter a root shell
and blank out the root password.
I haven't seen IRIX 5.X installation media for a *long* time.
One thing you can try to is boot to single user mode, but I'm pretty
sure IRIX will prompt
for the root password. I can't remember. The steps to boot into single
user mode depend
on the version of the PROM. Turn the machine on and hit the <ESC> key
to interrupt the boot cycle. You should see a menu system which allows
you to "Enter
the Command prompt" (or similar). This will put you in PROM mode where
At the prompt, type the word "single" and press Enter. If the PROM
indicates that it is
an unknown command, try the following command sequence instead:
sash: boot initstate=s
where ">>" and "sash:" are command prompts. If you're lucky, IRIX will
drop you into
a single user root shell. Otherwise, it will prompt for the root password.
If you don't care about the contents of the disk, your best bet is to
perform a fresh installation.
I've got an SGI Indy at home with IRIX 6.5.22 installed and it works
fine. Your only problem is
getting a copy of the installation media.
Should you need help performing the installation, take a look at the
docs at techpub.sgi.com or
let me know.
