Comment 18 for bug 315763

Actually, I have both problems (and more):

- firmware is not loaded by the netbooted installer in Karmic and in Lucid. I had to force it with "initrd=ubuntu-installer/amd64/initrd.gz,ubuntu-installer/amd64/aic94xx-seq.gz" hack. I didn't know about scsi-firmware udeb; looks like it's not working the way it's intended to.

- installer says "One or more drives containing Serial ATA RAID configurations have been found. Do you wish to activate these RAID devices?" and then fails to detect any drives (even though "fdisk -l" does list them). "d-i disk-detect/activate_dmraid boolean false" fixed that for me (https://answers.launchpad.net/ubuntu/+source/util-linux/+question/134126)

- after installation, firmware is not present in initrd (at least in Karmic); late_command like this fixes it:

for m in `echo /lib/firmware/*-generic /lib/firmware/*-server`; do
        cp -p /lib/firmware/aic94xx-seq.fw $m
done
update-initramfs -k all -t -u
