At your urging, I read the El Torito spec, and what you're saying above does not appear to be true of the Walnut Creek 3.2 install CD I have or the ISO image for the 3.3 install CD. What you're describing seems to be the "multiple boot image configuration" that's discussed in the spec. The 3.2 and 3.3 CDs appear to be of the "single boot image configuration" variety. Reading through the mkisofs man page, it that that the ISO image should contain all of the information necessary to make this CD-R bootable. Has anyone actually booted off of a CD-R that they've burnt from the September 17, 1999, image? The disc works fine for installing packages, etc., but it fails with an error during boot that looks something like "Booting from ATAPI CD-ROM: Failure." (Most of the machines around here have Award BIOS, and they all give that error.) Again, I'm using a copy of the burncd.sh script that I modified to reference /dev/rwcd0c instead of the HP burner described in the original script. I have an Acer 4432 CD-RW. The burncd.sh script uses wormcontrol and not cdrecord -- if cdrecord works with ATAPI CD-R/CD-RW drives the man page doesn't say so. The information on burning CDs under FreeBSD is very spotty. I've been to the freebsd.org site, dejanews, and altavista, only to scrape together fragments of info. I'd be happy to collect and organize this information if people out there have it.
