FreeBSD 7.0 SATA Controller

[Shaun Sabo]

Im trying to install FreeBSD 7.0 on a Dell XPS 600 desktop machine and im
having a lot of trouble with this. First I could not use USB keyboards with
the installer program (which is fine, i dont mind switching to PS2). then
once i got into the sysinstaller it does not detect my Hard Disks. i also
tried installing an old 6.2 cd that i had sitting around and remaking world
and kernel but when i installed the kernel and restarted to go into single
user mode the system could not mount the root filesystem. the motherboard im
using is a nvidia nforce4 with Serial ATA hard disks. Does anyone know how
to get FreeBSD 7.0 to recognize my hard drives?
