Description
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 read/
write per sector the drive can support.
This item allows you to enabled the transfer
access of the IDE DMA.
The integrated peripherals controller contains an
IDE interface with support for two IDE channels.
Choose Enabled to activate each channel
separately.
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 through 4 provide
successively increased performance. For
example, mode 0 data transfer rate is 3.3MB/s,
mode 1 is 5.2 MB/s, mode 2 is 8.3MB/s, mode 3
is 11.1 MB/s and mode 4 is 16.6MB/s. In Auto
mode, the system automatically determines the
best mode for each device.
