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) by increasing the data transfer rate to 256
bytes per cycle.
If your system does not boot after enabling this
parameter, this means that your HDD cannot support the function.
Therefore, you must change the setting to
Disabled
.
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
environment.
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
.
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 and Novell NetWare. If your
software or hard disk does not support this function, set this parameter
to
Disabled
.
