BIOS Utility 4-9
4.2.8 Enhanced IDE Features
Hard Disk Size > 504 MB
This enhanced IDE feature works only under DOS and Windows 3.x
environments. If enabled, 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. Other operating
systems require this parameter to be set to
Disabled .
To prevent data loss, set this parameter set to Enabled if you are
using a hard disk with more than 504 MB capacity that was previously
configured through LBA mode. If you use a hard disk configured
through cylinder-head-sector (CHS) mode, set this item to
Disabled
.
Hard Disk Block Mode
This function enhances disk performance depending on the hard disk
in use. If you set this parameter to
Enabled , it allows data transfer in
block (multiple sectors) by increasing the data transfer rate to 256
bytes per cycle. If your system does not boot after enabling this
parameter, change the setting to
Disabled . This parameter is
normally set to
Disabled
.
4.2.9 Num Lock After Boot
This parameter allows you to activate the Num Lock function upon
booting. The default setting is
Enabled
.
