Preamble : We had two servers running redhat 6.2 and we wanted
to upgrade to Debian since we had our qualms about installing RedHat
7.0 because of its broken compiler issue. Installing RedHat was pretty
simple since the hardware had been tested with RedHat and the default
kernel came with the necessary drivers if you were running Compaq
SmartArray. It was basically like doing it on another machine. With
Debian, the issue was different. We had a feeling that there might be
problems with the default kernel not supporting SmartArray and we were
right. It just didn't detect our drives.

Solution:

Boot from the Debian CD.

Using another linux machine, make an ext2 floppy with a directory called
'boot' that contains the kernel modules 'cpqarray.o' and if you are
using Compaq Proliant ML370, 'eepro100.o' (ethernet card). these kernel
modules can be located by :

	find /lib/modules/`uname -r` -name 'cpqarray.o'
	find /lib/modules/`uname -r` -name 'eepro100.o'

Compile a kernel on another machine with support for Compaq SmartArray
built-in. All required modules should be statically compiled. Make a
boot disk using this to be used later on, with:

	dd if=/usr/src/linux/arch/i386/boot/bzImage of=/dev/fd0

if the root partition of the intended server setup is going to be
/dev/ida/c0d0p2, assuming that /dev/ida/c0d0p1 is allocated for the
/boot partition, you also need to do the following to complete making
a boot disk :

	rdev /dev/fd0 /dev/ida/c0d0p2

At the text mode install, press CTRL-F2, to open up the second virtual
terminal and do the following :

	cd /dev
	mkdir ida
	cd ida
	mknod c0d0 b 72 0
	mknod c0d0p1 b 72 1
	mknod c0d0p2 b 72 2
	mknod c0d0p3 b 72 3
	.....
	mknod c0d0p15 b 72 15

This will create the necessary device files that Compaq SmartArray will
use. You need to create only the device files that will be used, others
can be skipped.

Return to the Debian Install screen by pressing CTRL-F1 and choose to
load essential modules from disk. At the prompt, insert the disk and
select the two modules individually.

Proceed with the install in the usual way, selecting the appropriate
device files created in a previous step to identify different partitions.

Reboot once the installation is over with the boot disk created in a
previous step in the drive. If all goes well, the kernel will spew out
messages and init will start and will then prompt you for some last
minute configurations.

Now transfer the kernel you made to the new system using another ext2
disk.  Put in the /boot partition.

Fire up 'vi /etc/lilo.conf' and type the following lilo.conf file assuming
that the new kernel is called /boot/vmlinuz

	lba32
	boot=/dev/c0d0
	root=/dev/c0d0p2
	install=/boot/boot.b
	map=/boot/map
	default=linux
	image=/boot/vmlinuz
		label=linux
		read-only

RUN '/sbin/lilo'. DON'T FORGET THIS STEP.

Take the floppy out of the drive and reboot. Your computer should now
start up in Debian.

Congratulations, pat yourself on the back.
