Disk Drives BIOS Utility
Type
This parameter lets you specify the type of hard disk installed in your system. If you want BIOS to
automatically configure your hard disk, select Auto. If you know your hard disk type, you can enter
the setting manually.
Setting this parameter also sets the Cylinder, Head, Sector, and Size parameters.
CylinderS
This parameter specifies your hard disk's number of cylinders, and is automatically set depending
on your Type parameter setting.
Head
This parameter specifies your hard disk's number of heads, and is automatically set depending on
your Type parameter setting.
Sectors
This parameter specifies your hard disk's number of sectors, and is automatically set depending on
your Type parameter setting.
Size
This parameter specifies the size of your hard disk, in MB.
Hard Disk Size > 504 MB
When set to Auto, the BIOS utility automatically detects if the installed hard disk supports the
function. If supported, it allows you to use a hard disk with a capacity of more than 504 MB. This is
made possible through the Logical Block Address (LBA) mode translation. However, the enhanced
IDE feature works only under a DOS or Windows 3.x/95/98 environment. Other operating systems
require this parameter to be set to Disabled.
Hard Disk Block Mode
This function enhances disk performance depending on 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 block (multiple sectors) at a rate of 256
bytes per cycle. To disregard the feature, change the setting to Disabled.
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.
Hard Disk 32-bit Access
Enabling this parameter improves system performance by allowing the use of the 32-bit hard disk
access. This enhanced IDE feature works only under DOS, Windows 3.x/95/98, and Novell
NetWare. If your software or hard disk does not support this function, set this parameter to Disabled.
DMA Transfer Mode
The Ultra DMA and Multi-DMA modes 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.
