Installing SATA on a P4PE motherboard?

[Gird]

I have just bought a WD 120GB SATA hard drive that I am trying to install on an ASUS P4PE motherboard.

I am currently running Windows 98 with two PATA hard drives.

I want to completely remove my PATA hard drives and install the SATA drive with Windows XP.

I have looked all over the BIOS for a setting that I can change to tell it to look for SATA with no avail. I have tried starting my computer with only my SATA drive installed, but it won't detect the drive. I have also tried putting my SATA drive in as a slave to my PATA drive that has my OS on it, but it still won't detect the SATA drive.

Can somebody please help??

Hmm if it's like my computer I had to enable the boot other device option, then find the SATA option. I don't have P4PE though so it might be different for you.
