IDE HDD Block Mode

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.

intervention. This improves data throughput and frees CPU to perform other tasks.

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.
