4-8 NEC Drivers and Utilities
If your IDE hard disk does not feature auto IDE type
detection or your IDE hard disk was formatted on another
system with parameters different than those reported by the
drive, you need to select “User Definable,” and set the
“Number of Cylinders,” “Number of Heads,” “Number of
Sectors,” and “Maximum Capacity.”
IDE Translation Mode
The IDE Translation Mode parameter controls the way in
which the BIOS interacts with the drive in terms of drive
geometry. Proper choice is dependent upon the drive’s size,
capabilities, and the operating system (OS) used. The
following choices are available.
Standard CHS
−
is the translation mode that has been in
use for years. Its use limits IDE capacity to a maximum
of 528 MB regardless of the size of the drive used.
Logical Block
−
mode overcomes the 528 MB maximum
size limitations imposed by the Standard CHS mode. It
should be used only when the drive supports logical
block addressing (LBA), and the OS supports LBA, or
uses the BIOS to access the disk.
Extended CHS
−
mode also overcomes the 528 MB
maximum size limitations imposed by the Standard CHS
mode. It can be used with drives that are larger than
528 MB, but does not support the LBA mode.
Auto Detected (default)
−
allows the BIOS to examine
the drive and determine the optimal mode. The first
choice is to utilize Logical Block mode if it is supported
by the drive. The second choice is to utilize Extended
CHS mode if the drive topology allows. If neither of the
above two methods is possible, then Standard CHS
mode is used.
