XP1000 21264 won't boot

My Alpha Workstation won't boot. This might be somewhat off-topic as it
is hardware related, but I know of no other forum to where I should
address this issue so I would appreciate some assistance.

When I switch it on, there is a long beep and then three short beeps. I
don't think the problem is with the video card as the machine should
default to serial console in the event that a video adapter is not
present (don't know about the case in the event of failure, though). I
don't have spare memory to check, but I had a look inside and four of
the 'A' slots are filled and none of the 'B' slots. I don't remember
whether this configuration is correct as it is a while since I used it last.

Unfortunately, I don't have the manual to check for error codes on
startup and Google couldn't help. I'd really like to get the machine
working again as they are getting rare to find and it is a great machine.

If memory servers correct, three beebs is a sign that its having memory
problems. Either a stick has gone bad or is the wrong size, parity, what
ever. You didn't state one thing in you post, did the computer EVER boot
since you've owned it? Will L G



last.

Yeah, it used to run perfectly. Sometimes it beeps as mentioned,
sometimes it gives no sound. I've tried removing and reinserting the
daughter card, as suggested elsewhere, and I'm about to try reinstalling
the memory.

Right now, it's not making any sound at all...

1L 3S is definitely a memory error. You can find out more by checking
the LEDs. In case you need a list to interpret them, ask me. I have one
available.

I took all memory modules out and replaced them (in different order) and
now it boots. I might check on E-bay to see if I can get s/h modules as
a replacement.

Thanks for the responses. I was worried it would be something not so
easy to replace.

This could very well be. Error codes (including the LEDs on the
CPU-board D21->D14) are like this:

LEDs error description beeps

1110 1001 Memory data path error 1S,3L
1110 1000 Memory address path error 1S,3L
1110 0111 Memory pattern test error 1S,3L

Solution:
Reseat & match DIMMs in bank Replace bad DIMM

Regards,

Marc

The problem seems intermittent and when I change the boards around, it
works again. Next time it happens, I'm going to get some compressed air
to clean the slots and clean the connectors on the memory modules with a
*** (eraser). If it still happens after that, new modules and a
spare daughterboard are next on the agenda.

...or, just try to reseat the existing memory in the same slots.

You can also find some folks very knowledgeable about Alphas over on the
comp.os.vms newsgroup. I usually only lurk here.

My guess is a bad CPU daughter card
B cache error !?!?!
