Multi-Sector
Transfers

Enhances disk performance depending on
the hard disk in use.

If you set this parameter to Auto, BIOS

Block Mode function. If supported, it
allows data transfer in blocks (multiple
sectors) at a rate of 256 bytes per cycle.

If you set this parameter to Disabled, data
transfer from and to the device occurs
one sector at a time.
