I cannot comment on this. Maybe someone else jumps in.

Depends on whether you enable the IDE disks in the CMOS.
If you enable the IDE disks the BIOS will boot from your IDE
disks. There is at least one bootmanager I know which is able
to boot from multiple disks/controllers (OSBS20B8.EXE).
If you want to boot IDE disks and SCSI disks as well I would
install the boot manager on either disks. The FreeBSD Boot:
prompt allows you to boot from sd when wd is also present and vice
versa.
