find the thread in the archive)
I have an Alphaserver 1000 that I would like to resurrect. It periodically hangs or
reboots. When it reboots the error is usually "Machine check while in palcode".
When it hangs, the hang is so severe the halt button does not work. Either way, it always
happens within 20 minutes of booting. I ran all of the diagnostics you get by moving the
CPU card jumper (cache memory tests, RAM tests) and they run for an hour or so with no
error. (I am assuming the diagnostic halts on error instead of just looping again, is that
correct?) During the course of these I moved the jumper to the wrong place and wiped out
SRM, so I had to reload SRM from floppy using the failsafe loader. That worked. The SRM
diagnostics will also run for as long as I want without error. Does anyone have any idea
what's wrong here or is there some kind of XXDP-like thing I can run that will better
test the machine?

I got A AS1000 on ebay as we speak. It woks fine but getting it ready I
found out a few things. TRU64 is really picky. If you have unsupported
cards or even supported cards with the wrong or outdated firmware you can
get machine checks.
Older version of BSD's Net, Free and Open will machine check. I use NetBSD
6.1 and it works fine in almost any configuration and even with cards with
outdated firmware (it will complain though)
If you have the StorageWorks backplane misconfigured it can machine check.
By the way, I had the Storage works backplane configured just to use the
qlogic 1020 controller and not the raid card, and I had concurrently 50/68
and SCA containerss and the AS1000 running Netbsd identified them all
correctly and I was able to read and write to all the disks even the SCA
one!!.

Hi Tom,
thanks for sharing your experience with the list !
There are two 1000A Alphaservers in my collection also waiting for a revival. They had
been used by a german TV-sender to broadcast publicity. I think I'm well prepared now
when I'm going to find the time to fire the systems up regarding pitfalls known about
these machines.
Kind regards,
Pierre

New subject: [OT] Help me finding a 1/16A 250V slow blow fuse
Hi!
I've some trouble finding a 1/16A (0.62mA) 250V slow blow fuse (3AGSB).
Most of online dealers show it as out-of-stock.
How can I substitute it or find a spare?
Thanks!
