When [Compatible] is selected Combined Option It allows you to select between [SATA 1, SATA 2], [SATA 1, IDE 1], and [IDE 1, SATA 2]. If it is set to [SATA 1, IDE 1], then SATAII_2 will not work. Likewise, if it is set to [IDE 1, SATA 2], then SATAII_1 will not work.
Because Intel ICH7 south bridge only supports two IDE devices under legacy OS (Windows NT), you have to choose [SATA 1, SATA2], [SATA 1, IDE 1], or [IDE 1, SATA 2] when the installed device is used with legacy OS.

[ARMD]: This is used for IDE ARMD (ATAPI Removable Media Device), such as MO. LBA/Large Mode Use this item to select the LBA/Large mode for a hard disk > 512 MB under DOS and Windows; for Netware and UNIX user, select [Disabled] to disable the LBA/Large mode. Block (Multi-Sector Transfer) The default value of this item is [Auto]. If this feature is enabled, it will enhance hard disk performance by reading or writing more data during each transfer. PIO Mode Use this item to set the PIO mode to enhance hard disk performance by optimizing the hard disk timing. DMA Mode DMA capability allows the improved transfer-speed and data-integrity for compatible IDE devices.
