Evening all,

Hopefully somebody can help as I've been trawling the interent to see if I can find the cause of a system boot error, with no luck.

I am running an old Alphaserver 3000 Model 700, using OpenVMS 7.1-1, nothing fancy attached, two internal hard drives and an external tape drive.

Everything was fine until sometime over the Christmas period when the system failed with a "Machine Check" error. When I now try to reboot the system, it goes through all the power up tests ok, and gets to the >>> prompt. I try to boot from here, and the system reports all the INIT phases ok, and then drops out with;

?07 MCHK FR PAL
PC = 00000000.00054023

And won't go any further.

Repeated attempts to boot the system mostly give the above error, but occasionally I get;

?06 MCHK DBL

It would be most welcome if anyone can shed any light on the possible cause of these error messages!

Thanks very much

A machine check is typically a hardware error.

Try removing devices from your configuration one at a time.

Sometimes re-seating a card will fix this problem.

Also check the clock battery. It may be hidden in a DIP watch chip.

Eisner was upgraded to the current Multinet Release. As part of that a new host key was generated. The old key was incompatible with newer Linux.

ssh to eisner is now giving (on linux) "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" , Has the server key in fact changed ?

HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
