PassThru IDE on boot

[vitalsyntax]

Every time I boot my PC the first message that shows up after the ASUS Mobo screen says:

Marvell 88SE91xx Adapter - BIOS Version
PCIe x1 5.0Gbps
Mode: PassThru IDE
Disk Information: No hard disk is detected!

After this screen the ASUS Mobo reappears and the computer boots normally. I'm wondering what this PassThru IDE screen means and if there is a way to make it not show up every time I boot.

Specs:
MOBO: ASUS P8P67 LE
CPU: i7-2600K OC 4.4GHz
GPU: GTX 570
RAM: 8GB 1600MHz
PSU: 800W
HDD1: 500GB 6GB/s 7200rpm Windows 7
HDD2: 500GB 6GB/s 7200rpm Mac OS Lion

I think that pass through means that it is a standard IDE mode controller and not set as RAID. I don’t think that you will be able to disable this message.
If anyone knows better let me know.

your sata ports may bet set to Native IDE mode
