Enhanced IDE Features
The Enhanced IDE Features section includes four parameters for optimizing hard disk
performance. These performance features depend on drive support. Newer drives support most
or all of these features.
3.4.8.1
Hard Disk Size > 504MB
If your hard disk size is greater than 504MB and you are operating in a DOS-based environment,
this parameter should be set to [DOS/Win3.x/Win95]. If you operate in NetWare, UNIX and
Windows NT environments, set this parameter to [Others].
[DOS/Win3.x/Win95].
3.4.8.2
Multiple Sectors Read/Write
This parameter enhances hard disk performance by reading/writing more data at once. The
available values include:
•
Auto
•
16 sectors
•
8 sectors
•
Disabled
As much as possible, set these parameters to [Auto] (when the
option to do so is available). This allows the notebook to use
the hard drive with the highest possible performance level.
The default setting is
