Today we had a blackout (too many air conditioners in the city ?) while I
was away. When power came back, our old Alpha 200/100 (which we use as
spare mail exchanger) had not switched off and got damaged. Of course it
is not under maintenance contract.
I found it on, the screen showed just the first "checkout" line
f4.eb.....ea.e9.e8.e7.e6.e5.
I can't remember what those codes are, and they are not listed in our
hardware manual for AlphaStation 200 Series (EK-PCDTA-UI.D01)
Anyhow, there was no >> prompt, so I could not boot.
I tried a few times a reset from the reset button. I also checked the LEDs
on the back of the CPU (pag. 4-10 of the h/w man) and they showed the
normal "console initialized" code (E5).
I then switched off and on the machine. Now the LEDs on the back showed
the code F7 "memory test 4 failure".
What does that mean ? One of the memory banks failed ?
I tried to switch the machine on again some times later, and now I'm back
to the previous situation ("console initialized" LED code, screen showing
f4.eb.....ea.e9.e8.e7.e6.e5., no >> prompt).
This puzzles me, transient memory error ?
Is there any quick solution to this before we junk the machine ?
Can I e.g. locate and remove the offending memory bank (will it run with
3 ?) Another possibility would be to cannibalize some spare parts from
another institute which had dismissed similar machines.
