How do PA RISC machines manage booting from CD?  How does one create
such a CD?

I am not sure exactly but you could try just writing the LIF image
to the CD.  Because HP's IPL can boot from a hpux file system, a PA
machine can probably also boot from a CD with a hpux file system
on it.  I doubt HP machines can boot from an ISO 9660 CD.

Most CD writing software has a mode that allows copying a binary
image file to a CD.  There are some issues regarding CD sector
size.  You want the image to be an integral number of CD sectors.

I am doing that as I read your post.  The Ignite-UX toolkit available on
software.hp.com has the tools to do this.  See make_medialif.  I make a
HFS file images that have Ignite golden images and SD software depots.
make_medialif creates the LIF file with the INSTALL boot and Ignite
config stuff. The instl_combine command wraps the LIF file containing
the INSTLALL kernel and INSTALLFS filesystem around my HFS image file. I
then use cdrecord to write the whole enchilada to CD-R.
