Setup and Operation 2-15
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 are possible, then
Standard CHS mode is used.
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’s 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 a different manner.
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 drive in
order to operate in the mode.
OS/2 2.0 and Novell 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 which
supports this advanced geometry.
You will get better performance not using “Fast 32-bit IDE” if using a drive which employs
Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports
these advanced modes.
Language
The installed language will appear in the Setup and BIOS text strings. English (US) is the
default in the U. S. and Canada.
