Parameter Description
Hard disk Enhances disk performance depending on
block mode the hard disk in use. If you set this
parameter to Auto, the BIOS utility
automatically detects if the installed hard
disk drive supports the Block Mode
function. If supported, it allows data
transfer in blocks (multiple sectors) at a
rate of 256 bytes per cycle.
Advanced When set to Auto, the BIOS utility
PIO mode automatically detects if the installed hard
disk supports the function. If supported, it
allows for faster data recovery and
read/write timing that reduces hard disk
activity time. This results in better hard
disk performance.
Hard disk 32 Improves system performance by allowing
bit access the use of the 32-bit hard disk access. This
enhanced IDE feature works only under
DOS, Windows 3.x, Windows 95,
Windows NT, and Novell NetWare. If your
software or hard disk does not support this
function, set this parameter to Disabled.
DMA transfer The Ultra DMA and Multi-DMA modes
mode enhance hard disk performance by
increasing the transfer rate. However,
besides enabling these features in the BIOS
Setup, both the Ultra DMA and
Multi-DMA modes require the DMA
driver to be loaded. By setting this
parameter to Auto, BIOS automatically
sets the appropriate DMA mode for your
hard disk.
