MCP SATA Mode

► SATA Operation Mode

This item is used to set the operating mode of your SATA ports. The available options are:

[IDE] - This congures the SATA ports to support legacy PATA mode or SATA mode.

[AHCI] - The Advanced Host Controller Interface (AHCI) specication describes the register

level interface for a Host Controller for Serial ATA. The specication includes a description of

the hardware/software interface between system software and the host controller hardware.

AHCI provides more advanced features including SATA features, but some SATA drives may

not support AHCI, unless they are labeled with AHCI support in its specication.

If your motherboard supporting AHCI, and you have a SATA device, which also supports AHCI,

then you can select IDE option to have fair performance (only PATA, SATA level), or you can

select AHCI to get its best performance.

[RAID] - When you enable RAID, it means all your SATA drives must also support AHCI.

[Linux AHCI] - For advanced Linux system if it supports AHCI, then you can select this option.

► SATA Pri-Master RAID / SATA Pri-Slave RAID / SATA Sec-Master RAID / SATA Sec-Slave

RAID

These items are valid only when "SATA Operation Mode" is set to RAID. They are used to

enable or disable the RAID function of each SATA port on the motherboard.

The relationships between RAID settings and SATA ports on the motherboard are :

SATA Pri-Master RAID is the SATA port 1 of the motherboard.

With your motherboard and SATA hard disk both supporting AHCI, you had better set

this BIOS setting to AHCI, then install your Operating System (such as Windows XP).

Later, if you ever change this BIOS setting to IDE, OS still can run.

But if you at the rst time set this setting to IDE, then install the Operating System.

Later, if you change this BIOS setting to AHCI, this operating system can not run.
