The file AIC7xxx-1.2.10-patch-Jun14.gz contains the source code to the
driver used. It applied cleanly to the 1.2.13/ELF tree as shipped with
Red Hat 2.0

Additionally, four Red Hat 2.0 boot images are provided:

2940.img	       - full of stuff but it seems to choke on many machines
			 (includes 3C509 support)
2940-nonet.img         - no networking and no sbpcd type CD's
2940-sbpcd-nonet.img   - no networking but with sbpcd type CD's
2940-bare.img          - no networking or non SCSI CD's
2940-bare-atapi.img    - no networking and just SCSI and IDE CD's

You'll probably want to build your own kernel after installation. This
should apply the patch for you.

cd /usr/src/linux
gunzip < AIC7xxx-1.2.10-patch-Jun14.gz | patch -p1

Then just build a kernel like always.

Good luck!
