I second this. We had some really esoterical effects using an AHA-2940
for booting from another disk than the first two. fsck always found
errors that weren't there if booting from drive 0/1. It was really
funny.. If you don't want to get into trouble don't use this facility 
with any *ix (I forgot to mention this happened with Linux, but FreeBSD
should be no diff).
