        ^^^^^^^^^^^^^^^^
Is this a typo? Should it read `wd(2,a)/kernel'?
And then you should enter `1:wd(2,a)/kernel' at the boot prompt to tell
                           ^
the bootcode to choose the second bios drive to boot the kernel from.

In which step of the booting sequence do you get the `bad disklabel'
message?

Which release of FreeBSD do you run?

Use `Custom' from the main menu of /stand/sysinstall and do
*not* try to install from the boot.flp but instead login as root
and type `/stand/sysinstall'. But I don't think you'll have to do
any customization from `/stand/sysinstall' to support moving the
disk from one IDE port to another.

The (W)rite option shows up on my system and it probably works
well, but I didn't try it, because ones in a while I reboot it I
built a new kernel.

Check `10.5 storage devices' in the handbook. You also might consult
the manual pages (man boot, man disklabel ...) and the FAQ (`2.18
how can I add my new hard disk to my FreeBSD system')

Hope this helps
