Intel DX58SO mobo issues with eSATA ports

[Bloohat]

I setup 2 eSATA ports so I could plug in removable hard drives. My computer doesn't recognize the media. I know the SATA ports work, as all my hard drives are using SATA ports on the mobo. I'm currently running windows xp pro 64 bit. I know my media works, because I can connect to it via USB or firewire, just not eSATA. Am I missing a driver or setup files for my motherboard? I recently flashed my motherboard's bios and updated it.
