OnChip IDE Device

IDE HDD Block Mode

Block mode is otherwise known as block transfer, multiple commands, or multiple sector read/write. Select the

“Enabled” option if your IDE hard drive supports block mode (most new drives do). The system will

automatically determine the optimal number of blocks to read and write per sector.

Options: Enabled (default), Disabled

On-Chip Channel 0/1 PCI IDE

This item lets users enable or disable the IDE channel.

Options: Disabled, Enabled (default)

IDE Channel 0/1 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 Channel 0/1 Master/Slave UDMA

Ultra DMA functionality can be implemented if it is supported by the IDE hard drives in your system. Your

operating environment also 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, select “Auto” to enable BIOS support.

Options: Auto (default), Disabled
