The DEC 3000/500S hardware I'm using is flaking out.  I'm getting
thousands of "Warning: received processor correctable error" even to
the point that under even modest load now (e.g., the /etc/daily run)
the machine will sometimes spontaneously reboot (logs inform me
"savecore: reboot after panic: panic: trap").  This is not good. :-(

Fortunately, there's an AlphaStation 1000A here in the lab that they
want to surplus that I've asked to use to replace the DEC 3000/500S
that's ailing.  I've no experience with non-TurboChannel alphas, so I
was wondering if there were any "gotchas" I should be aware of when
migrating NetBSD onto the 1000A?

In particular, the boot log states "Firmware revision: 5.5-75."  I did
an online search and the latest firmware for the 1000A is listed as
V5.7.  However, I vaguely remember some firware "upgrades" to be
retrograde steps for some of the PCI alphas (e.g., it leads to boot
problems, etc.).  Is it okay to upgrade the 1000A to V5.7?  (I'm
presuming it's running SRM as it's currently running Tru64 5.)

Also, it apparently has two DEC TULIP ethernet cards in it:

  tu0: DECchip 21140: Revision: 1.2 
  tu0 at pci0 slot 11 
  tu0: DEC TULIP (10/100) Ethernet 
   _Interface, hardware address: 
   _00-00-F8-02-10-1C 
  tu0: console mode: selecting 100BaseTX 
   _(UTP) port: full duplex 
  tu1: DECchip 21040: Revision: 2.4 
  tu1 at pci0 slot 12 
  tu1: DEC TULIP (10Mbps) Ethernet 
   _Interface, hardware address: 
   _00-00-F8-22-C9-B6 
  tu1: console mode: selecting 10BaseT 
   _(UTP) port: half duplex 

What is the recommended driver for these?  (I seem to recall there
being two, one of which is considered "buggy," or am I confusing this
with something else?)

Finally, is this graphics adapter supported under X?

  cirrus0: Cirrus Logic CL-GD5428 (SVGA)
   _512 Kbytes
  cirrus0 at eisa0

Sorry for the questions, but although this model is listed as being
supported from 1.4 onwards, I couldn't find any mention of it in the
"Notes on Supported System Models" page at the NetBSD WWW site.

FWIW, appended at the end is the Tru64 boot log entry, in case
anyone can spot any obvious problems with hardware compatibility.

Cheers,

Paul.
