Not sure it'll work. Pretty sure it won't now... I thought that FreeBSD's boot programs were installed on sd0 and once they took control of the system they no longer needed the BIOS and would have no problem loading the kernel off of sd2 (although as I write this I remember a discussion of booting that talked about switching between protected mode and real mode to access the BIOS <sigh>).

Guess I'm trying to do the impossible here. I'll rearrange my drives and try again. Thanks for your feedback!! (and all of the rest of your effort) -jim
