3.3.4 IDE Configuration

OnBoard IDE Operate Mode

Please select [Compatible Mode] when you install legacy OS (Windows

ME / 98SE) into SATA device. If you install legacy OS into IDE HDD while

SATA devices are used, you also need to select [Compatible Mode].

If native OS (Windows 2000 / XP) is installed into SATA device, please

select [Enhanced Mode]. You also need to select [Enhanced Mode]

while native OS is installed into IDE HDD and SATA devices are used.

If you do not install any SATA device, please also select [Enhanced Mode]

no matter you use legacy OS or native OS for the system.

Please note that the following options will be varied depending on the

“OnBoard IDE Operate Mode” ([Compatible Mode] or [Enhanced

Mode]) that you selected.

When [Enhanced Mode] is selected:

OnBoard IDE Controller

You may enable either the primary IDE channel or the secondary IDE channel.

Or you may enable both the primary and the secondary IDE channels by

selecting [Both]. Set to [Disabled] will disable the both. Configuration options:

[Disabled], [Primary], [Secondary], [Both].

When [Compatible Mode] is selected

Combined Mode Option

It allows you to select between [Pri IDE + SATA] and [SATA + Sec IDE]. If

it is set to [Pri IDE + SATA], then the secondary IDE will not work. Likewise,

if it is set to [SATA + Sec IDE], then the primary IDE will not work.

Because Intel

ICH5 south bridge only supports four IDE devices

under legacy OS (Windows ME / 98SE), you have to choose either

[Pri IDE + SATA] or [SATA + Sec IDE] when the installed SATA device

is used with legacy OS.
