Is the virtual machine using SCSI emulation to boot, or is it using IDE? SCSI drives are da(4), IDE drives are ata(4) [aka ad(4)] If the boot blocks (maybe boot0 specific) point to an ad/ata device, and the virtual machine is SCSI, it won't find the boot sectors. Personally, I use the "standard" boot blocks which don't allow multibooting but I don't multiboot BSD anyway. The standard boot blocks work by finding the first bsd slice, and booting it. I like the keyword find because it doesn't direct the boot blocks to something unfindable. :D Let me know the subsystem layout, and we'll work from there. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
