IDE HDD Block Mode

Block mode is also called block transfer, multiple commands,

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

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”.
