Sorry for not mentioning points 2 and 3 before.
So diagnostic mode can take hours to finish? Really?
Well, if so, this is the first machine with OpenBoot I have experienced which takes a significant amount of time to run / finish diagnostics.
Don't confuse diag mode with POST. Diag mode tests everything right down to cpu registers and it just takes for ever. A system will auto switch to diag mode after a few crashes / failed boots. You can't break from it unfortunately, you have to wait till its finished before you can break and do a set-defaults to clear the diag level.
