UW SCSI PCI cards

UW SCSI PCI cards

[Saulnier, Geoff (London)]

Hi!

My apologies fro posting to both lists, but this is a question that I think
applies to both...

Finally managed to get linuxppc installed, from the CD, onto my Beige G3
minitower.  It has a PCI Ultra-Wide SCSI card and 2 4Gb UW SCSI disks of
that card.  I had to install it onto a 1Gig Jaz cart because of the
following problems:

No matter how well partitioned my drives were (with Mac pdisk), the intaller
would not see them, and pdisk in the linux X installer environment would not
see them.  In fact, it would see not partitions at all of any kind.

When I formated and partitioned a Jaz cart, with the drive on the external,
ordinary SCSI bus, it was seen by the installer and things went fine from
there.

So, my questions are:
  -  what PCI UW SCSI cards are supported in the final version
  -  are there any plans to support others (I am assuming that the one that
came in my box is not supported!)
or
  -  does this problem sound like it has nothing to do with the card?

Thanks for any help!!

That depends on the exact model of PCI SCSI card you have. If it's an
original Apple part, it should be recognized by the installer. If not,
chances are that it doesn't contain OpenFirmware code to make it
recognized upon boot; so the installer will not see it.

Plus, I don't know what SCSI drivers are built into the installer.

Basically all that Linux supports, although some more exotic ones might
not work on PowerPC...

Sure.. hack them yourself so that they work on PowerPC ;-)

As I said, it's either the card lacking OF code, or the installer
lacking the proper driver.

If the latter is your problem, you can always install on the Jaz, then
builkd a kernel including the driver for your SCSI board, then copy the
whole system over.

FYI, my Sym53c875 board (Dawicontrol DC-2976UW) doesn't have an OF ROM, but it
works fine with the {sym,ncr}53c8xx drivers. So OF is not a prerequisite,
unless you want to boot from it as well.
