read/writes per sector the drive can support.
¾ 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.
¾ 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 default value is
“Enabled”.
NOTE Choosing Disabled for these options will
automatically remove the IDE
rimaryMaster/Slave PIO and/or IDE Secondary
Master/Slave PIO items on the menu.
¾ 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.
¾ 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.
