I already have the firmware on initrd - pulled from
/lib/firmware on the main disk, which was built using the
mentioned qlogic firmware package.
So, I'm guessing I'm just missing the udev stuff
then...hmm....
Quick question - how does mdev and udev differ? It seems to
be running mdev, which something I came across mentioned
that it is a udev replacement seemingly for initrd images.
Any how...
how do they differ?
And could I just pull the udev files from the main disk to
do the work?
I really hope I can get this working sometime on Friday -
that's my last day for being able to get this system
working.
TIA,
Ben
P.S. Sorry, I would have replied in-line, but the new Yahoo!
interface is a real pain for replies.

Ben,
you're almost there. Get the binary firmware from
ftp://ftp.qlogic.com/outgoing/linux/firmware (just get the
.bin files, not
the .bin-version files). There are five or six files
altogether. You don't
need all, but they are relatively small so it's no big deal
putting all of
them in /lib/firmware.
Make sure on the initramfs you have /etc/udev/rules.d/ with
appropriate rules,
including one to handle firmware loading. Also make sure
you have on the
initramfs /lib/udev/firmware.sh. This script is part of
udev. Just copy it.
Then recreate the cpio.gz and try again. My guess is you
forgot to include
the actual firmware. But you're getting very close to a
working system 
Oh and last but far from least, you need a working /init
script on the
initramfs. All it needs to do is mount /proc, /sys, /dev as
a tmpfs, start
udev, mount the actual rootfs device (as per your silo.conf)
and switch_root.
