Thanks for your replies Anders and Shawn.
I am pretty sure that you need a CD-rom that supports 512 byte blocksize
for this to work in your alpha.
OK, I'd noticed the line marked below and wondered if it was significant.
>>>b dkc400

One of the jumper pairs on rear of the Plextor PX-W4012S is labelled BLOCK.
The manual says:
BLOCK: Block size. You may need to change this setting if you are working in
a UNIX environment and want to boot from your PlexWriter.
I put a jumper across those two pins and tried booting the PWS again:

So, the "block size is not 512 bytes" warning went away but it still didn't
work. :(
I also tried booting an XP1000 from this CD using the CD drive which came
with the machine, a Compaq CRD-8322B. That's an IDE drive and doesn't have a
jumper pair labelled BLOCK, but presumably it's configured to be able to boot
from a 512-byte-block CD like this, but it didn't work either:

I wonder if there's something wrong with the way I'm burning the cdhdtape
file to the CD?
