IDE DMA transfer access
Automatic data transfer between system memory and IDE
device with minimum CPU intervention. This improves data
throughput and frees CPU to perform other tasks.
IDE 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 interface supports. Modes 0 to 4 provide
successively increased performance. In Auto mode, the
system automatically determines the best mode for each
device.
IDE Master/Slave UDMA
Select the mode of operation for the IDE drive. Ultra DMA-
33/66/100/133 implementation is possible only if your IDE
hard drive supports it and the operating environment
includes a DMA driver. If your hard drive and system
software both support Ultra DMA-33/66/100/133, select Auto
to enable UDMA mode by BIOS.
