If it's not capitalized, it always complains that it can't open the
device.

I've pointed it to both 0:3 and 0:0, neither seem to satisfy it.

Believe me, I type boot many times each time I try. ;P
Today I looked at my G4s OF settings. It had the boot-device set to
'mac-io/ata-disk@<number>@0:0'. Looking at the dev / ls on my Umax, the
<number> is 20000. So I set the Umax's boot-device to 'ata/ATA-
Disk@20000@0:0'--and it didn't fail to open, and didn't run into the
claim error.
The error this time was that it couldn't open the boot-file, which was
set to '/vmlinux root=/dev/hda3'. I had a copy of the kernel I use
there. I also tried setting boot-file to '/boot/ben-2.2.18.gz
root=/dev/hda3', which it still complained about.
I've also tried appending 'ata/ATA-Disk@20000@0:3' and 'ata/ATA-
Disk@20000@0:0' to the beginning of the path. It still says it can't
find it.

Resetting OF / reinstalling quik hasn't changed its behavior.
Does this look like a hopeless cause? Unless there's more documentation
out there, I don't know what else to try.
Thanks,
Ben
