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 suports the Block Mode function.
If supported, it allows data transfer in
blocks (multiple sectors) at a rate of 256
bytes per cycle.
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
98, Windows NT, Windows 2000, and Novell
Netware. If your software or hard disk
does not support this function, set this
parameter to Disabled.
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. To disregard the feature,
change the setting to Disabled.
DMA
The Ultra DMA and Multi-DMA modes
Transfer
enhance hard disk performance by
Mode
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.
