I've also been looking at El Torito, and figured that they've invented a lot of useless crap. :) If i'd give it a try, i would use the emulationless approach. We've got plenty of space on the CD's (there's 32 KB unused space before the cd9660 f/s starts), this should be enough even for an X11-based bootstrap loader. ;) If you want a self-contained CD-ROM bootable file system, you probably need some MFS root version. Btw., i've also downloaded their guide how to make a bootable CD from an image, but dismissed it instantly. I don't think it's worth the Internet bandwidth. Writing a bootloader is certainly the smallest part when designing a CD-bootable BSD. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
