Right. At present you need to enable the second SATA port in the
BIOS. Disabling it also disables the first port from being
recognized by the driver. It's a figment of the "compatability mode"
that the PE750 runs in. I believe Stuart Hayes sent Jeff a patch to
address this, but I can't find it handy...
