Re: Debian Installation upon an Alpha Server 4000 5/400



[this has nothing to do with the debian installer AFAICS; M-F-T set.]

It's possible that this is a question of firmware versions, either on the
alpha or on the SCSI card.  The card I'm currently booting my alpha from is:

00:06.0 SCSI storage controller: Adaptec AHA-2940U/UW/D / AIC-7881U (rev 01)

I previously booted the machine using the QLogic ISP1020 that came stock,
but unfortunately the driver support for that card seems to have atrophied
in Linux 2.6 and it can no longer access the disks.

How does these cards show up under lspci?  The only useful reference to
KZPSA that I find on Debian lists seems to imply that this is the same as
the Mylex DAC960 so commonly seen.  The DAC960 module is included in the
installer, as part of the scsi-extra-modules udeb; I know this was
historically supported, but that there were also some problems with it early
in 2.6 because of the non-standard device names that it exposed.  These are
probably worth a try, anyway.

Of the other cards you inquired about, the DAC960 cards and the QLogic
ISP1040 are probably the best bets.  The ISP1020 does not work for me, but
the later QLogic cards are still widely used.
