For the basic procedure, see the FAQ. However, one important piece missing from the FAQ is that you may have to use the "boot0cfg" command to enable LBA booting (this is REQUIRED if your FreeBSD partition is above the 1024-cylinder/8GB limit, assuming your BIOS supports it, and virtually all recent BIOSes do). See the boot0cfg man page for more info. Note that the boot0cfg uses the term, "packet", to refer to LBA booting. Among other things, you need to use the boot0cfg option, "-o packet". Read the man page. -- Darryl Okahata darrylo@soco.agilent.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Agilent Technologies, or of the little green men that have been following him all day.
