Enhanced IDE Features
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). If your system does not boot after enabling
Disabled
this parameter, change the setting to
. This parameter is
normally set to
Enabled
.
Advanced PIO Mode
Enabling this parameter allows for faster data recovery and read/write
timing that reduces hard disk activity time. This results to better hard
disk performance.
To utilize this feature, your hard disk must support the advanced PIO
mode. If not, set this parameter to
Disabled
. Refer to your hard disk
documentation for information about the advanced PIO mode.
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, keep 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. When you use a hard disk configured
through the cylinder-head-sector (CHS) mode, set this parameter to
Disabled
.
