IDE DISK DRIVER FOR NETWARE 3.1X 4.0X (IDE.EXE)
Supports IDE current parameters
---------------------------------------------------------------
This package is made up of the following files:
IDE DOC14CJ4 - This document
IDE EXE14CJ4 - Binary self-extracting file
The file, once downloaded with the binary oprion, needs to be
run as it is a self-extracting file.
ABSTRACT:
Novell Labs has certified these IDE drivers for NetWare v3.12
and v4.02. This version of the IDE driver provides enhanced
support for Current Parameters. Current Parameters is a
feature of some of the newer IDE drives. A potential problem
with host computer BIOSes that translate IDE drive parameters
(heads) on drives which do not support Current Parameters is
described.

SYMPTOM
Symptoms may include ABENDs soon after the driver is loaded and
the drive has been accessed. Other problems may be partition
conflicts which will likely result in DOS partition accesses
overwriting NetWare or NetWare overwriting DOS. File loss or
corruption or inability to mount volumes would be likely
symptoms.
NOTE: These symptoms and the solution apply in cases where the
host computer's BIOS translates the IDE drive geometry. BIOS
manufacturers will be able to verify that the BIOS translates
drive geometries.
CAUSE
Previous versions of the IDE.DSK driver used the DOS partition
table parameters to define the drive geometry for NetWare.
This method was reliable until host computer BIOSes implemented
translation of the IDE drive geometry. Now, that the DOS
parameters are unreliable, the IDE driver has been enhanced to
read "Current Parameters" from the drive. The driver will use
Current Parameters (CP) if the drive supports them. Some
drives do not support CP. This driver will give the following
error message if it detects BIOS translation and the drive does
not support CP:
IDE-040: Drive xx does not support current parameters. Drive
not registered with OS.
Potential Problems:
If the drive does not support CP, then the IDE driver cannot be
certain what the actual used parameters are. If the user
desires, the driver may be loaded with a "/c" parameter which
will permit the driver to continue. However, Novell will not
be responsible for any problems encountered when the driver is
used in the /c mode.
When the IDE driver is loaded: load ide /c port=xx int=x, a
message and a warning will appear:
IDE-045: Drive xx does not support current parameters.
**WARNING** Novell does not recommend using this drive in this
configuration.
If the translating BIOS does not set the drives parameters to
other than the native parameters, then even drives which do not
support CP should work. The problem arises if the translating
BIOS sets the drives parameters to other than native and the
drive does not support CP. In that case, the IDE driver has no
method of determining what the used parameters are and in such
a case the potential for overlapping DOS and NetWare partitions
exists. Overlapping partitions will lead to corruption, loss
of data and/or inability to mount volumes.
SOLUTION
Use IDE.EXE. Replace your current IDE.DSK with the appropriate
3.1X or 4.0X IDE.DSK from IDE.EXE. NOTE the potential problems
in the CAUSE section above.
