Well, you need to create a new installation image for this, probably. That's at least the standard way. Previously, this required that you run `make release', albeit i believe it should now be possible to create just the bootfloppy only using the stuff under /usr/src/release/floppies. An alternate way would be to create a complete filesystem, and a CD bootstrap. However, during my work on cdboot (/sys/i386/boot/cdboot), i found that only very few vendors and sometimes even controller BIOS revisions actually implement the El Torito specs good enough, so you might have to see first whether your controller can really boot such a CD at all. (The normal bootable CD stuff only emulates a floppy image, but advanced functions like accessing the CD-ROM using BIOS functions is not tested by this.) If you want to follow this line, you're going to make some experiments... Also, you need some modified startup scripts, with an MFS /var (and a symlink for /tmp). I have been successful in producing such a CD once, but: YMMV. -- 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. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
