I have successfully installed Linux with the FirePort 40 (last night, in
fact!)  I did have a couple of problems due to my own stupidity, but
nothing serious.  This is for RedHat 4.2.  I'm not sure about installing
other distributions.  Here's what I did:

1. Grab RedHat boot and support disk images from
   ftp://linux.wauug.org/pub/roudier/redhatboot/4.2 and create the boot and
   support disks (see the RedHat documentation for details)
2. Boot the machine with the RedHat boot disk, answering all the questions.
   When asked about a SCSI controller, choose "NCR 53c810/820 (alternate)",
   and it should find the FirePort.
3. When you've finshed installing, reboot with the RedHat boot disk, and
   enter "rescue" at the prompt.  Answer the questions again.  This time,
   for the SCSI controller, choose "NCR 53c810/20/..../75".  Again, it
   should see the FirePort.  
4. When you get to a shell prompt, type
      installncr /dev/sda1
   where /dev/sda1 is replaced with whatever partition your root partition
   is. This is where I made my mistake - the readme file that comes with
   the boot disk uses /dev/sda1, and it didn't occur to me until about 1:30
   AM that, for my setup, the root partition is /dev/sda2...  Details,
   details :-)

After that, it's been working just fine.  Hope this helps.

This controller is based on the NCR53c875J chip. Support for it is included
in the ncr53c8xx driver, although you will need kernel 2.0.31 or later
(preferably, 2.0.32) for it to work.

Meaning that the standard RedHat 4.x kernels will not recognize it.

I patched the RedHat kernel 2.0.30 with Gerard Roudiers
(1.12d-to-2.5d)-upgrade and compiled both,
kernel AND modules, giving the new ncr53c8xx.o
which I could succesfully load via insmod within both
the original AND the new kernel
and which shows up at least a controller as /proc/scsi/ncr53c8xx/0
I do not own devices yet for more.

What's the meaning of the posting reply of Henrik
that You need at least 2.0.31??
...puzzled...

1. Need help with RedHat install w/ two SCSI controllers

I am having problems with a Red Hat install.  I purchased Special
Edition Using Linux (Third Edition) from QUE and I am trying to
install the included Red Hat 4.1.  I initially had problems getting
the CDROM to recognize that the Red Hat CD was present, but the QUE
web site (http://www.mcp.com/que/selinux/) provided new boot disk
images which do see the disk when it is in the drive.  

Now on to my next problem.  I am running a Compaq Deskpro XL 5100
system with an AMD SCSI controller built in.  I also installed an
Adaptec 2920 controller, (the built in controller did not allow me to
use external SCSI devices and internal SCSI devices simultaneously).
I have three one gig drives and the CDROM on the AMD controller and an
external 1.3 and an internal 4.0 gig drive on the Adaptec.  I used
PartitionMagic (great program!) to split the 4.0 gig drive into 4
partitions, partition 1 for NT Server, partition 2 for Win95,
partition 3 for Linux and partition 4 for the Linux swap partition.

When booting off the linux boot disks the install routine does not
find the second SCSI controller (which has the drive I want to install
onto), it seems to find the internal AMD and assume it's the only one.
Now I know that these boot images can see an Adaptec2920  controller
because I used them to install Linux on my office PC (Compaq Deskpro
4000).  In that case I have IDE and SCSI, I had to tell it that I was
using SCSI and tell it what controller (the 2920 works under one of
the Future Domain drivers).  My problem at home is that I never get
asked about SCSI, it is just getting done automatically.  

Am I able to toggle over to the command prompt and load something
which will make Linux "see" the Adaptec card?  I know if I put the 4
gig drive on the AMD controller I would be able to do this, but I am
sure there is a software way of working this problem out.

Thanks for the help...
