Just a wild guess:  That either the first or second disk didn't
really get an MBR written to it - or the third party boot manager
on the first disk might not play nicely with the one on the second 
Try using fdisk (from the install CD fixit if necessary) to write 
the FreeBSD MBR to both disks.   You can put the other third party 
booter back afterward if desired/needed.
