Just another data point. I have right now, temporary, pc164 machine
here. It is not without its problems, but
boot -t iso9660 scd0:kernels/pc164.gz root=/dev/scd0
works like a clockwork every time. Just to make sure that I am sane
and not seeing things I tried it now, and it greeted me with
an initial screen of Red Hat install. It checks during the boot
if /tmp is writable, and discovering that it is not it remounts root
on a ram disk. It may be a question of a controller (the machine
here has NCR inside). The CD is one from "Red Hat Archives" and a full
Alpha set.

I was, actually, using more often

boot -t iso9660 scd0:kernels/pc164.gz root=/dev/sda2

for recovery purposes and it saved my skin. :-)

I was also booting UDB from the same CD with the same command
and kernels/noname.gz image and also it worked fine.
