Advanced PIO Mode
When set to Auto, the BIOS utility 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. The default setting is Auto.
Hard Disk 32-Bit Access
Enabling this parameter improves system performance by allowing the use of 32-bit hard
disk access. This enhanced IDE feature works only under DOS, Windows 3.x, Windows
98, and Novell NetWare. If your software or hard disk does not support this function, set
this parameter to Disabled . The default setting is Enabled.
DMA Transfer Mode
The Ultra DMA and Multi-DMA modes enhance hard disk performance by increasing the
transfer rate. However, in addition to 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. The default setting is Auto.
CD-ROM Drive DMA Mode
Set this parameter to Enabled to enable the DMA mode for the CD-ROM drive. This
improves system performance since it allows direct memory access to the CD-ROM. To
deactivate the function, set the parameter to Disabled . The default setting is Disabled.
