BIOS Setup

2-19

following options:

On-Chip Primary / Secondary PCI IDE

The integrated peripheral controller contains an IDE interface with

support for two IDE channels. Select Enabled to activate each channel

separately.

The Choices: Enabled

(default), Disabled.

IDE Prefetch Mode

The “onboard” IDE drive interfaces supports IDE prefetching for faster

drive access.

If the interface does not support prefetching. If you install

a primary and/or secondary add-in IDE interface, set this option to

“Disabled”.



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 through 4 provides successively increased performance. In Auto

mode, the system automatically determines the best mode for each

device.

The Choices: 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.

The Choices: Auto


IDE HDD Block Mode

Block mode is also called block transfer, multiple commands, or multiple

sector read / write. If your IDE hard drive supports block mode (most

new drives do), select Enabled for automatic detection of the optimal

number of block mode (most new drives do), select Enabled for

automatic detection of the optimal number of block read / write per

sector where the drive can support.
