PC 8150 User's Manual
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/writes per sector the drive can support.
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.
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
willautomatically remove the IDE rimaryMaster/Slave
PIO and/or IDE Secondary Master/Slave PIO items
on the menu.
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 your system
software both support Ultra DMA-33/66/100/133, select
Auto to enable UDMA mode by BIOS.
