On a boot partition you need to have a slice, so you probably should use:

1:ad(2,1,a)/boot/loader

this will try to boot from ad2s1a, a likely name for a boot partition on the secondary master PATA disk. You may also press "?" at the prompt and get a list of devices. Also, for your /etc/fstab you may wish to use a label instead. Read up on man glabel on how to set these up. The idea is that, by giving a disk a unique label, you can setup your /etc/fstab without worrying on what controller/cable/connector te disk is on. So doesn't matter if its ad2 or ad8, it will show up as /dev/label/mydisk and you can setup your /etc/fstab accordingly.

Good luck!
