Refer to the section “Parallel ATA and Serial ATA device configurations” on page 2-24 for the appropriate settings of the IDE Configuration items under different operating systems.

Enhanced Mode Support On [S-TA]A

The default setting S-ATA allows you to use native OS on Serial ATA and Parallel ATA ports. We recommend that you do not change the default setting for better OS compatibility. In this setting, you may use legacy OS on the Parallel ATA ports only if you did not install any Serial ATA device.

The P-ATA+S-ATA and P-ATA options are for advanced users only. If you set to any of these options and encounter problems, revert to the default setting S-ATA.

Configuration options: [P-ATA+S-ATA] [S-ATA] [P-ATA]

The Enhanced Mode Support On appears only when the item

Onboard IDE Operate Mode is set to Enhanced Mode.

Configure SATA as RAID [No]

Allows you to configure the S-ATA channels to function either as standard IDE or as RAID. Configuration options: [Yes] [No]

Serial ATA BOOTROM [Disabled]

Allows you to enable or disable the Serial ATA boot ROM.

Configuration options: [Disabled] [Enabled]

The Serial ATA BOOTROM appears only when the itemConfigureSATA as RAID is set toYes.

IDE Port Settings [Primary P-ATA+S-ATA]

Allows selection of the IDE ports to activate if you are using a legacy operating system. Set to [Primary P-ATA+S-ATA] if you wish to use the primary Parallel ATA and Serial ATA ports, or set to [Secondary P-ATA+SATA] to enable the secondary P-ATA port instead. Setting to [P-ATA Ports Only] disables the two Serial ATA ports supported by ICH5. Configuration options: [Primary P-ATA+S-ATA] [Secondary P-ATA+S-ATA][P-ATA Ports Only]
