I installed Vista Ultimate x64 on a RAID0 disk array of WD Raptors on an
Abit IP35 Pro motherboard. The other disk drives are all SATAII. I notice
the message "AHCI Bios Not Installed" during the boot sequence. The disk
drives are NOT hot swappable. Reading up on AHCI, it seems this supports hot
swap and NCQ for SATA drives. 

All the drives are connected to the ICH9R controller and it seems there is
no way to independantly select between RAID, IDE and AHCI for the drives.
Since I am booting from a RAID0, I have selected RAID for the controller. 

Am I missing something that would allow me to make the other drives
hot-swappable? My last system used nForce4 and all the drives were
hot-swappable. The lack of hot-swap is not an issue, but am I also losing
out on NCQ? 

I have googled the problem, but have not found my circumstances. Most seem
to focus on installing on IDE and then switching to AHCI. Others seem to
indicate that RAID implements AHCI, but I wonder since I do not have the
hot-swap feature.

Curiosity killed the cat, but I still find myself bothered by the "AHCI Bios
Not Installed" message each time I boot.

Any insight is most appreciated!

Thanks,

Jim Maki
