¾ IDE HDD Block Mode
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.
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”.
