See section 4.3.6 "IDE Configuration" of the user manual.
"Configure SATA As"
*******
AHCI mode supports NCQ (native command queuing, useful for
multiple programs accessing the disk simultaneously, such as on
a file server), and AHCI also support "hot plug" of the hard drive.
(This external device, allows plugging in a raw hard drive
mechanism while the computer is running. It is an example
of "hot plug". I would not do this, due to the danger of
shaking the drive while it is still spinning. It might be safe
to plug it in, but ejecting the drive is more dangerous.)

The AHCI mode, if selected before you install the OS, also makes
it easier to upgrade to a RAID driver later on, after
the OS has been installed. Those are some reasons to
use that mode.
Windows 7 has a built-in AHCI driver, so selecting that
setting in the BIOS, should work without an issue. But if you're
dual booting WinXP (have two separate disks, Win7 on
one disk, WinXP on the other disk), you'll need to change
the BIOS setting "Configure SATA As" back to the original
value, in order to get the old installation of WinXP to work.
And Fogar, the other respondents have given you sound advice.
By using a new and separate hard drive, to hold Windows 7,
and disconnecting the old WinXP hard drive for now, that will make
it easier to return to your old configuration later. It is
like making a backup, a backup of a system where all your
software works. You know how difficult it is to configure
and load the drivers to make that system of yours work, and
you may need to go back to WinXP, if Windows 7 causes problems.
If you still have the Matrox Real Time Video Editing card, it may
not have a Windows 7 driver, and may fail to work. That alone, may be
a reason to stick with the WinXP that is working. The Matrox card
may not have Windows 7 64 bit drivers.
