Use modprobe instead, or insert the required modules first.

It looks like more than "user error" to me...
There is a coiple of people complaining on newsgroups.

System:

RH 6.0, kernel 2.2.5-15 & 2.2.5-20

The problem:

Kernel module ppa (Parallel ZIP drive) gives errors during boot
(before /etc/conf.modules is check!) and after boot while inserting
manually. The 2.2 kernel handles ppa diffrent than 2.0. You can
install ZIP manually by

# insmod parport; insmod parport_pc; insmod ppa

but jaZip application coredumps and leaves system in notstable state.
This is an ugly work around for people that depend on parallel ZIP and
upgraded from 5.2 to 6.0.

found the problem:

modprobe gives also errors (modprobe ppa)
file /lib/modules/2.2.5-15/modules.dep needs to be edited

line:
/lib/modules/2.2.5-15/scsi/ppa.o: /lib/modules/2.2.5-15/misc/parport.o
/lib/modules/2.2.5-15/misc/parport_pc.o

without "parport_pc.o" modprobe ppa gives errors

I got module insertion working fine using appropriate entries in
rc.modules on bootup and the appropriate entries in conf.modules.  Go
the the parport driver website and read up on the new parport
driver.  I used info gleaned from there to make things work for me.
Email and I'll let you know exactly how I set mine up.

*** Bug 3430 has been marked as a duplicate of this bug. ***

When booting with the Red Hat floppy, the parallel zip
drive (via scsi4) is not detected, probably because
support is not in the kernel. (I happen to know that
you have to use scsi to access the parallel port zip).

When I select, during installation at item "SCSI
Configuration", "Do you have a SCSI adapter? Yes" and
"Iomega PPA3 (parallel port zip" + "Autoprobe", I get
the error: "I can't find the device anywhere on your
system!". Virtual console 3 (Alt-F3) reveals:
"* running /bin/insmod /bin/insmod /modules/ppa.o"
"* insmod failed!"
Note the double /bin/insmod, which imho is an erroneous
call. However, when I try in Alt-F2 console:
/bin/insmod /modules/ppa.o
I get the error: "Cannot find archive member ppa.o:
file does not exist in archive".
Note that /modules is properly symlinked to the right
directory on the, also properly mounted, cdrom.

As far as I can tell, the only problem here is in the install,
since correctly using modprobe instead of insmod fixes the problem
outside of the install.  I am therefore changing the component to
"installer".

Issue is resolved in the latest installer, as the ppa module in not included in
the installer modules, as the Zip drive cannot be used for installation.
