Pegasos won't boot

[Wilse]

I also posted this a Morphzone but I'm guessing I'll get as much response here.

After my 'audio partition invalidated' problem, which some of you may have read about, I now have another problem.

My Peg won't boot.

I put the drive back into the peg, on the IDE channel nearest the front of the machine, at the end of the cable.
On switching on, the MOS (1.4) logo comes up, then all I get is a black screen.
If I boot from the MOS1.3 CD, it boots but no HD is shown.

Any ideas?

If all else fails, can you reformat it and reinstall the OS?

Well, I can't get the drive to show up on the Peg at all so I can't install anything on it.

It now shows up on my A1 but I don't think I could install MOS1.4 from there - then again, maybe it's just a case of copying the files over from the CD?

@JKD:

Can you see the device or partitions from the open firmware?

I can see them all via scsi config.

Entirely possible the MBR (Boot Sector) or RDB has become corrupted I guess, however, given that you get the MOS logo....safe to assume it finds the first FFS partition and the boot.img .. so I doubt it's an MBR problem.

Have to confess, I'm pretty clueless in this department.
(As if that wasn't obvious. :-D)

@JKD:

I think you are getting the right advice on MZ anyway. So I'll discontinue here.

Noted, thanks. :pint:

I'm absolutely delighted to report that my Pagasos, as of about a
minute ago, is now back to normal!

@Tomas:

I've fixed it already but that's pretty much how I did it.
There were just some additional niggles that took a while longer to iron out.
