Boot problem (hangs at/in loader)

I installed FreeBSD on a disk and have this problem:
The boot manager comes up and shows:
F1: FreeBSD
F5: Disk 2

If I hit F1 (or wait a few seconds),  The 'puter drops down a line, 
shows a minus (-) sign in the bottom left hand corner and stays there 
until I hit any key on the keyboard.

I ran:
   boot0cfg -B /dev/ad0
and the problem did not go away.  What else could I try so that the 
computer will boot/reboot unattended?
