I'll assume your SCSI card is the same as mine, though I had to buy the card
separately.  (It was IOmega branded, though;  "ZIP ZOOM", IIRC.)

When you rebuild the kernel, enable "SCSI support" and "SCSI disk support" (and
optionally "Verbose SCSI error reporting").  These are under "SCSI support" if
you use 'make xconfig' to configure your kernel.

Also enable "Adaptec AHA152X support".  This is under "SCSI low-level drivers" if
you use 'make xconfig'.

You can make any/all of these modular if you only use your ZIP intermittently.
If you do, edit /etc/conf.modules and add these lines:

    alias scsi_hostadapter aha152x
    options aha152x aha152x=0x340,10,7,1

The example in the howto uses an 11 where I have the 10, but I had to change it
to 10 to make it work.  You should probably read the howto before you start
anyway; click it up at http://metalab.unc.edu/Linux/HOWTO/mini/ZIP-Drive.html.

If you use modules you will also need to do the mkinitrd stuff to pick up these
changes.  If you've never rebuilt the kernel before, read up on it before you
start, and be sure to make a safe copy of /usr/src/linux/.config so you'll have a
clean slate if you mess up.  The mkinitrd procedure should be described in your
documentation for rebuilding the kernel

Good luck,

I have one of these drives, on a different type of SCSI card.

If you have a stock RH 5.1 kernel, there should have been a set of
related SCSI driver modules installed with it.

If the Iomega card is an Adaptec variant, the command:

   modprobe aha152x

might work.  There are a variety of SCSI modules in the directory
/lib/modules/preferred/scsi .

Have the zip drive powered on when you do this so the initial
probing will detect it.  Still have to mount the disk ...

I was never able to get RH5.1 to probe my Iomega SCSI Interface which was stamped I
believe with AHA1505 (or something close). I believe my card was set up as IOport
220 and IRQ11. I never could get it to probe or get the AHA152X module to load. All
of this happened when it all worked fine under Windoze. I was able to get an
AHA1522B and a AHA1542CF which initially gave me the same problems under Linux but
worked fine under Windoze. I even reinstalled completely after I bought a new 4gb
disk for Linux and RH5.2. What did the trick for me was to manually set the IOport
to either 330 or 334 on the 1522 or 1542 which allowed the SCSI Adapter to Autoprobe
and installed just fine. I didn't use IOport 330 as that was a conflict with my SB16
sound card. Port 334 works like a champ. I never did go back to the Iomega SCSI card
as i like the throughput I get on the 1542CF much better.
