NEC Drivers and Utilities 4-9

CAUTION
When set to Auto Detected, the BIOS will detect
what the drive is capable of, not the translation
mechanism which was used to format the drive.
If a drive is run in a mode other than the mode in
which it was partitioned and formatted,
unpredictable results may occur, including data loss.
Different OS have different abilities regarding IDE
translation modes:
UNIX
−
does not currently support either LBA or ECHS
and must utilize the Standard CHS method. UNIX can
support drives larger than 528 MB, but does so in its
own way.
OS/2 2.1 and OS/2 WARP
−
can support LBA, ECHS,
or Standard CHS methods. Note that LBA support may
require a switch setting on an OS/2 driver in order to
operate in the mode.
OS/2 2.0 and Novel Netware
−
can support either,
ECHS or Standard CHS methods, but not LBA.
DOS and Windows
−
can support LBA, ECHS, or
Standard CHS methods. If the “Fast 32-bit IDE” option
of Windows is utilized, make sure to use the Standard
CHS setting only, unless a version of WDCDRV.386 is
being used that supports this advanced geometry.
You will get better performance not using “Fast 32-bit
IDE” if using a drive which employs Mode 3 PIO or greater
on the PCI interface, unless using a version of
WDCDRV.386 that supports these advanced modes.
