Yes that driver is somewhat large, but do we have size constraints? 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
