Fun with 'fdisk -B -b /boot/boot0 ad0'

Greetings-
	I've got a laptop which I dualboot between -CURRENT and W2k.  I recently 
had to reinstall W2k, and in the process it eliminated my MBR.  I can 
successfully boot into FBSD by using a boot floppy and telling it to boot 
the kernel from the hard drive, but this is, well, kludgy.  Checking the 
handbook, I found the entry on how to reinstall the MBR.  So, I did a 
'fdisk -B -b /boot/boot0 ad0'.  The FreeBSD boot program came back, 
however, when I attempt to load FreeBSD, it merely beeps at me.  It will, 
however, boot into W2k.  I've tried supping, rebuilding the boot blocks (cd 
src/sys/boot; make install; fdisk -B -b /boot/boot0 ad0; disklabel -B 
ad0s2) with no success.  I was hoping that someone might have an idea, as 
I've exhausted all of mine for the time being.
