Thanks for the info.

Unfortunately, we still do.  In our ISOs, we use El Torito 2.88 MB
floppy disk images.  I think we need to move to ISOLINUX and
non-emulated CD boot, even though this means dropping support for
CD-booting on some old machines.  I'd appreciate a patch against our
native tree that will make this change cleanly (suitable for commit) -
including introduction of ISOLINUX as a new package, changes to the
owl-cdrom package and to makeiso.sh.  Perhaps some other changes will be
needed as well...

Also, I'd appreciate some info on what kinds of machines we'll be
dropping support for CD-booting on with this move.  My gut feeling is
that none of the Pentium Pro machines (produced in 1990s, yet still
theoretically supported by Owl so far) will boot a non-ElTorito CD.
That's fine.  But what about the various Pentium II and Pentium III
machines?  I think the P3 ones still matter a little bit.  My gut
feeling is that some (if not all?) of them won't boot non-ElTorito CDs,
but I did no research.  And what about P4 and newer?

Thanks,

Alexander
