I followed the very helpful docs at
<https://www.dan.me.uk/blog/2010/02/08/booting-from-zfs-raid056-in-freebsd-8-0-release/>https://www.dan.me.uk/blog/2010/02/08/booting-from-zfs-raid056-in-freebsd-8-0-release/
to get an 8.1R AMD64 install working booting purely off a zfs
mirror! However, one small issue I ran into is with AHCI enabled in the BIOS.
I did the install directly to disks ada0 and ada1 as I loaded AHCI
from the boot DVD's loader prompt. Everything booted up great.

Then, I took out the DVD ROM drive (CD1) that I installed from and
went to reboot. This time, the box would insta reboot just after the
'BTX Loader' text would appear. I then put back the DVD ROM and
rebooted, still the same problem. Then, I went into the BIOS and
forced the DVD to be the first boot device, just like it was at
install time... Everything booted up fine once again.?!?!
Then, I pulled the DVD drive and I rebooted the box and disabled
AHCI in the BIOS and used just regular enhanced mode, and all booted
up just fine.

Is there something additionally that needs to be set for ahci to work
in this manner ?
