Setup and Operation 2-13
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 its use. If neither of the above two methods is 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 that 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 you are using a drive that
employs Mode 3 PIO or greater on the PCI interface. However, you can use “Fast 32-bit
IDE” to increase performance if you are using a version of WDCDRV.386 that 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.
