That's up to your BIOS. FreeBSD will mount / from the
gmirror, which will be backed by one or more disks. Earlier
stages will use BIOS to load the kernel, etc.
May I suggest {{{
When I configured gmirror on a server, I felt safer pulling
the plug than disabling it the normal way. That way I could
evaluate that:
1) my BIOS settings are correct regarding booting
from both disks.
2) gmirror is doing what I wanted it to do.

You can detach an ATA channel using "atacontrol detach".
Since your disks are on different channels, that's probably
what you asked for. Not all controllers/controller drivers
support this.
