ATA/IDE Configuration

Please select [Compatible] when you install legacy OS (Windows NT). If native OS (Windows 2000 / XP) is installed, please select [Enhanced].

When [Compatible] is selected

Combined Option It allows you to select between [SATA 1, SATA 2, SATA 3, SATA 4], [SATA 1, SA TA 3, IDE 1], and [IDE 1, SATA 2, SATA 4]. If it is set to [SATA 1, SATA

3, IDE 1], then SATAII_2, SATAII_4 will not work. Likewise, if it is set to [IDE

1, SATA 2, SATA 4], then SATAII_1, SATAII_3 will not work.

Because Intel® ICH7 south bridge only supports four IDE devices

under legacy OS (Windows NT), you have to choose [SATA 1, SATA 2,

SATA 3, SATA 4], [SATA 1, SATA 3, IDE 1], or [IDE 1, SATA 2, SATA 4]

when the installed device is used with legacy OS.
