You've connected your second drive as the master on the second bus; 
it's drive 1 (of 0,1) to the BIOS, but drive 2 (of 0,2) to FreeBSD.

You can either move the drive back to the first bus (quicker), or boot 
with '1:wd(2,a)kernel -s', mount /dev/wd2s1a on / (and other 
filesystems from there if you need them), update your /etc/fstab file 
to refer to 'wd2' rather than 'wd1', then put the boot string you used 
above in /boot.config.
