Would it do any good to try to reverse engineer the boot process from a
HP-UX CD?  I have the hpux 8.01 distribution, and the install cd boots on my

This is going to be fairly HP specific.  It is highly likely that it would
be different for 300/400 than 700/800.  If you get a hold of a bootable
CD, the best option might be to attempt to reverse engineer the process.
The only bootable thing that we have ever had for 300s was tape.

There is some in information on the web on how to create bootable Sun
CDs.  Not HP, but they are definitely non-El Torrito.  From the Sun CD-ROM

'Until just recently, creating a bootable CD-ROM on SPARC was a mystery
(even though the RedHat people have had a Sun bootable RedHat distribution
available for quite some time now).

     See "docs/CDROM.HOWTO" in "silo-0.8.4.tgz" at

This might be useful.  I glanced at it and it seems that Sun treats a
CDRom just like it would any other disk.  So the image on the CDRom must
look like a disk image.
