Refer to the section “Parallel ATA and Serial ATA device configurations” on page 1-22 for the appropriate settings of the IDE Configuration items under different operating systems.

Enhanced Mode Support On [S-ATA]

The default setting S-ATA allows you to use native OS (Windows 2000/XP) 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 (Windows ME/98/98SE/NT4.0) 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.

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]

The IDE Port Settings appears only when the item Onboard IDE Operate Mode is set to Compatible Mode.

IDE Detect Time Out [35]

Selects the time out value for detecting ATA/ATAPI devices. Configuration options: [0] [5] [10] [15] [20] [25] [30] [35]
