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.
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.
LEGACY Mode Support

Legacy mode support allows devices to function in an operating environment that is not
USB-aware.
