Getting Started, Documentation, Tips & Tricks

After few years I try to start my O2 (R7k 600) again. There were some problems with reseating and so. Now I have green light, O2 logo, boot sound, than disk read few sectors, monitor turn to black and nothing go ON. Led is still green.

I have figured out that I can run sash trough build in console, there I can list hdd (ls) whitch sucessfuly list it. But when I try to boot unix or unix.save I got blank screen. Can it be damaged HDD?

Is there some useful commands in sash? I can even cat file (says no device).

Thanks for hints

First I would try to boot the system in single user mode.

Tested with 'single' command - still black screen -- I'll try resetenv as a next step, than I try to boot Installation CD.

I figured out that I have only "installation" disks 6.5.22 downloaded years ago from sgi supportfolio. So my next step is to chase "fully working" set of disks.

EDIT:

When I start installation from CD's O2 go black after again after "copyiing installation tools" part. So problem is somwhere else (not HDD). Memtest(2,3) show no errors. All basic test pass. I will try to change memory sticks anyway and see what will happend...
