The system BIOS should have no entry for attached drives.  The system
BIOS is only used for IDE interfaces.  Since you are booting off of the
2940, you must enable its BIOS.

If you partitioned your disk under DOS with Extended BIOS translation
on, then you will totally confuse FreeBSD by turing it off.  FreeBSD
will take the geometry from the BIOS, it will conflict with the geometry
(255/64/8192) used to set the DOS partition boundaries in the partition 
table.  If you want to be able to have FreeBSD and DOS coexist, you must 
partition with and leave the board in the same translation mode.  Since you 
already have DOS installed, I would suggest going back to having Extended 
translation on.  Make sure that the install program sees that you have a 
255/63 translation at that time.
