IDE channel0 /channel1 /Master / Slave UDMA
Ultra DMA 100 functionality can be implemented if it is supported by the IDE hard drives
in your system. As well, your operating environment requires a DMA driver (Windows 95
OSR2 or a third party IDE bus master driver). If your hard drive and your system software
both support Ultra DMA 100, select “Auto” to enable BIOS support.
Options: Auto (default),Disabled
***OnChip Serial ATA Setting***
On-Chip Serial ATA
This option allows you to select the on-chip Serial ATA operating mode which will
determine how you will use your Serial ATA drives with the other standard IDE drives.
This system can physically attach 2 IDE drives and 4 SATA drives but will have certain
limitations as described below.
Options:
Disabled Disable on-chip serial ATA. No Serial ATA devices installed.
Auto(default) BIOS will auto-detect the presence of any SATA devices.

98/ME can recognize IDE devices but cannot directly
recognize an SATA device and therefore you must use this mode to allow the SATA device
to simulate an IDE device by assuming the role of one IDE channel in the system. This
means that you will have one available IDE channel for 2 SATA drives to use (each IDE
channel can support 2 IDE drives). If you were to install all both IDE drives and 4 SATA
drives, you will only see 2 of the SATA drives along with the 2 IDE drives.
Enhanced Mode In this mode, you can use all 6 hard disk drives (including 2 IDE
drives and 4 SATA drives).
Note:
You cannot use “Enhanced” mode with Windows® 98/ME. It only support to install
Windows® 2000/ XP if you want to boot from SATA device. (It’s restriction from Microsoft.)
SATA Only Select this option when you install SATA drives only.
PATA IDE Mode
This option allows you to select an IDE channel for PATA IDE devices. When you install the
SATA device(s) to the SATA1 or 3 or 1+3, this option should be set to channel 1. When you
install the device(s) to the SATA2 or 4 or 2+4, this option should be set to channel 0.
Options: Channel 0 (default),channel 1
SATA Port
This option will display which IDE channel will be used to the SATA device.
Options: SATA2, 4 is channel 1
