I'm no expert, but after nearly 30 years around this stuff this is
what I figured out after poking around the source.  Others may have
more sound counsel.  Modify the src/2.4.x/Makefile and remove
'-DMODVERSIONS' and '-include $(SRCPATH)/include/linux/modversions.h'.
You may need to modify the 'BOOTOBJS = iteraid.bot' compilation
block also.

iteraid.o:iteraid.c iteraid.h
        $(CC) $(CFLAGS) $(shell if uname -r | grep '2.2.' >
/dev/null 2>&1; then echo "-DMODVERSIONS"; fi) -I. -I$(SRCPATH)/drivers/scsi
-I$(SRCPATH)/include -include $(SRCPATH)/include/linux/modversions.h -c -o iteraid.o iteraid.c

Yes.  'cat /proc/version' will show you what is booted.

These I don't remember exactly; it has been a couple of months since
I did the installation.  With a versionless module I avoided caring. :-|

The driver diskettes are loaded very early in the boot process if
you choose expert mode, so I don't know why you haven't been able to
use the 9500S driver diskette.

It may be easiest to install the system onto a scratch 4+GB standard
IDE drive and just get the thing to boot.  Once you do that you can
play with loading the supplied drivers or recompiling as needed, all
under the native OS.  That way you avoid version conflicts.

A useful little install script is below to copy the compiled module
to the correct /lib/modules kernel directory.  It goes into the
driver source directory.

==================
#!/bin/sh
if [ "$1" = "" ]; then
        echo "usage: install kernel_version (e.g.
2.4.25)"
        exit
fi
rm -f iteraid.o
make
cp iteraid.o /lib/modules/${1}/kernel/drivers/scsi
==================
