IDE DMA Transfer Access
Set this option to Enabled to specify that the IDE controller on the PCI
local bus has bus mastering capability. Setting options: Disabled, Enabled.
OnChip IDE Channel 0/1
This setting enables or disables the internal primary and secondary IDE
controllers. Setting options: Disabled, Enabled.
IDE Prefetch Mode
The onboard IDE drive interfaces support IDE prefetching, for faster
drive accesses. When you install a primary and/or secondary add-in IDE
interface, set this option to Disabled if the interface does not support
prefetching. Setting options: Disabled, Enabled.
Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO
mode (0-4) for each of the four IDE devices that the onboard IDE inter-
face supports. Modes 0 through 4 provide successively increased
performance. In Auto mode, the system automatically determines the
best mode for each device. The settings are: Auto, Mode 0, Mode 1, Mode
2, Mode 3, Mode 4.
Primary/Secondary Master/Slave UDMA
Ultra DMA transfer mode implementation is possible only if your IDE
hard drive supports it and the operating environment includes a DMA
driver (Windows ME or a third-party IDE bus master driver). If your
hard drive and your system software both support Ultra DMA/33, Ultra
DMA/66, Ultra DMA/100, Ultra DMA/133 select Auto to enable BIOS
support. The settings are: Auto, Disabled.
