If your drives are currently /dev/hda, etc. they will change to /dev/sda, etc.
Some people really don't like that because they have configs setup
that depend on the name.
Also /dev/sdX naming is dynamic. So if you are the type to plug in
drives, etc. from time to time, you need to make sure you don't depend
on your drives being any specific /dev/sdX name. You can use
mount-by-label etc. to do that, but I admit to finding it more trouble
than its worth and still use /dev/sdX. I know enough to make it work
in general.
The good news is that both mdraid and LVM tag the disks/partitions
with identifiers, so they don't depend on the /dev/sdX name.
Also, AHCI is effectively a controller spec.
Some implementations are great, others not so great.
What chipset is it? Once you know, google for issues.
== note
If the MB is from the last 2 or so years, I'd expect good support.
Some of the older stuff is more problematic.
