Intel PX875P warranty OnChip Serial ATA Setting, IDE Primary/Secondary/Master/Slave PIO

PX875P PRO/ PX875P

IDE Primary/Secondary/Master/Slave PIO

The IDE PIO (Programmed Input / Output) fields let you set a PIO mode (0-4) for each of the IDE devices that the onboard IDE interface supports. Modes 0 to 4 will increase performance incrementally. In Auto mode, the system automatically determines the best mode for each device. Options: Auto (default)、Mode0、Mode1、Mode2、Mode3、Mode4.

IDE Primary / Secondary /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 field 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 4 IDE drives and 2 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.
	Note: When using the “Auto” mode with Windows®
	98/ME/2000 and installing drives on all 4 IDE connectors and
	both SATA drives, the system will only recognize 2 of the IDE
	drives along with the 2 SATA drives (this will be similar to the
	“Combined” Mode – see below).
Combined Mode	Windows® 98/ME/2000 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 of the two IDE channels in the
	system. This means that you will only have one available IDE
	channel left, leaving you with a total of 2 IDE drives and 2
	SATA drives for use (each IDE channel can support 2 IDE
	drives). If you were to install all four IDE drives and both
	SATA drives, you will only see 2 of the IDE drives along with
	the 2 SATA drives.
Enhanced Mode	In this mode, you can use all 6 hard disk drives (including 4
	IDE drives and 2 SATA drives).
	Note: You cannot use “Enhanced” mode with Windows®
	98/ME/2000. It only support to install Windows® XP if you
	want to boot from SATA device. (It’s restriction from Intel.)
SATA Only	Select this option when you install SATA drives only.
