As others have said, you probably are better off with getting your
application to run under 5.3.  However, assuming that this motherboard is
using an ICH5 southbridge, you should be able to configure the BIOS to run
the SATA channels in legacy mode.  To do this, go to the IDE Configuration
menu and make sure that the 'Enhanced mode' setting is off and that Legacy
Configuation setting is either in 'S-ATA' only or 'P-ATA and S-ATA'.  This
will make your sata disks appear to be normal IDE drives, but you'll loose
access to one or both of your normal IDE channels, depending on which
option you pick.

I'm not guaranteeing that this will work, but it's easy to try.  If you
decide to go with FreeBSD 5.3 then you'll want to reset the BIOS to
Enhanced mode.
