DIRECTIONS FOR LINUX KERNEL ON THE WISC DB CLUSTER

COMPILATION
Use a 2.2.12 kernel, like this one: http://www.kernel.org/pub/linux/kernel/v2.2/linux-2.2.12.tar.gz
Using a later edition will make either the tulip network card or afs unhappy.

For the raw I/O patch:
Get the patch from http://oss.sgi.com/projects/rawio/
be in the untarred kernel source dir and type:
patch -p1 < sgi+straw2.2.13.patch
This patch will work ok even though it was built for the 2.2.13 kernel

Tulip driver:
Copy over the existing Tulip driver with an improved version, one from:
/afs/cs/i386_rh61/src/i386_rh61/drivers/tulip/tulip.c

Run make xconfig
(if you want to run this remotely and it complains about tunnelling when you are root, you can chown -R yourusername on the source dir)
- again, if you want to enable the raw I/O patch, select it in the SCSI support section.
- pick the Tulip driver in the ethernet network card section
- pick Adaptec AIC7xxx in the SCSI driver section.  The kernel will work with the TCQ and other stats enabled too (although we didn't use those for our project).
- important: select "support for console on serial port" in character devices section.

run make dep and make bzImage

INSTALLATION
Pretty standard.
Copy the kernel to /boot
Add your kernel to /etc/lilo.conf, duplicating a the primary listing and changing the image name and label.
Type: lilo, sync, sync, reboot
