REL_OS2.TXT
****************************************************************************
* SYSTEM REQUIREMENTS *
****************************************************************************
Hardware:
1. The driver included in this package is intended for use on Pentium(tm)
processor based 82430FX systems ONLY.
2. Ensure that a mouse is connected to the system.
3. Do not use any other add-in IDE (PCI or ISA) card in the system during
installation.
Operating System:
1. IBM OS/2 2.x or Warp* 3.x must be installed on the system prior to
installing the driver.
2. Perform installation off of the on-board primary PIIX IDE interface.
BIOS:
The BIOS must properly initialize the PIIX IDE interface for bus master
operation.
****************************************************************************
* INSTALLING THE DRIVER *
****************************************************************************
The following procedures for the installation of the PIIX Bus Master IDE
Driver for OS/2 (PIIXIDE.ADD) are specific only to the version of the driver
currently contained within this package.
The following procedures assume that the OS/2 operating system was installed
properly on the target system, and that the standard PIIX IDE driver,
IBM1S506.ADD, was used. If IBM1S506.ADD was not used, the driver which
replaced it should be un-installed before installing PIIXIDE.ADD.
Furthermore, if IBM1S506.ADD was not originally installed on the target
system, it should be installed first, and the system re-tested with it,
before installing PIIXIDE.ADD.
Automatic Install Procedure:
****************************
1. Run the install utility (INSTALL.EXE). INSTALL.EXE copies PIIXIDE.ADD
from the source directory to the target directory, and changes the
CONFIG.SYS file to install it.
Command line format: install [options]
Command line options:
/s:<source path> Specifies the path to the directory containing
PIIXIDE.ADD. The default source is the directory
containing INSTALL.EXE.
/t:<target path> Specifies the path to the directory where
INSTALL.EXE will copy PIIXIDE.ADD. The default
target is the \OS2 directory on the boot drive.
/tu:<boot path> Specifies the path to the directory containing
the CONFIG.SYS file. The default directory is
the root of the boot drive.
/l:<logfile> Specifies an optional log file. If this option
is used, the output will be redirected to the
specified file, and INSTALL.EXE will run
unattended.
All command line parameters are optional. The install utility will not
install the PIIX Bus Master IDE driver if it cannot detect an Intel
82430FX PCIset.
2. Shutdown and reboot the system.
Manual Install Procedure:
*************************
1. Copy PIIXIDE.ADD to the \OS2 directory on the boot drive.
2. Make the following changes to the CONFIG.SYS file:
Replace:
BASEDEV=IBM1S506.ADD
with:
BASEDEV=PIIXIDE.ADD
3. Shutdown and reboot the system.
Note: The PIIX Bus Master IDE driver auto-detects DMA capable drives and
configures them and the Intel 82430FX PCIset for bus master DMA
transfers.
****************************************************************************
* COMMAND LINE SWITCHES *
****************************************************************************
1. Adapter Switch: /A:x where x is 0, 1, 2, or 3.
This selects the adapter that will be referenced by subsequent
switches.
2. Unit Switch: /U:x where x is 0, 1, 2, or 3.
This selects the unit that will be referenced by subsequent switches.
3. Bus Master Disable Switch: /!BM
This will disable the bus master DMA feature. This capability is fully
auto-detected by the driver. If for any reason it is desirable to
disable bus master DMA transfers, this switch can be used on a per
adapter or per unit basis. If used after a /A:x switch but prior to
any /U:x or /UNIT:x switch, then bus master DMA transfers will be
disabled for all units on the adapter. If the bus master disable switch
follows both /A:x and /U:x (or /UNIT:x) switches, then bus master DMA
transfers will be disabled only on the specified unit.
4. All other option switches are same as for the "IBM1S506.ADD" driver.
****************************************************************************
* UN-INSTALLING THE DRIVER *
****************************************************************************
The following procedures are specific only to the version of the driver
currently contained within this package. These procedures assume that the
OS/2 operating system was installed properly on the target system, and that
the PIIX Bus Master IDE driver, PIIXIDE.ADD, was properly installed according
to the procedure described above.
Automatic Un-install Procedure:
*******************************
1. Run the un-install utility (UNINST.EXE). UNINST.EXE removes
PIIXIDE.ADD from the target directory, and changes the CONFIG.SYS
file to re-install IBM1S506.ADD.
Command line format: uninst [options]
Command line options:
/t:<target path> Specifies the path to the directory containing
PIIXIDE.ADD. The default target is the \OS2
directory on the boot drive.
/tu:<boot path> Specifies the path to the directory containing
the CONFIG.SYS file. The default directory is the
root of the boot drive.
/l:<logfile> Specifies an optional log file. If this option is
used, the output will be redirected to the
specified file, and UNINST.EXE will run
unattended.
All command line parameters are optional.
2. Shutdown and reboot the system.
Manual Un-install Procedure:
****************************
1. Make the following changes to the CONFIG.SYS file:
Replace:
BASEDEV=PIIXIDE.ADD
with:
BASEDEV=IBM1S506.ADD
2. Delete PIIXIDE.ADD from the \OS2 directory on the boot drive.
3. Shutdown and reboot the system.
****************************************************************************
* SUPPORTED DEVICES *
****************************************************************************
In general, bus mastering is possible for ATA fixed disk and ATAPI devices
that support the following DMA timing modes:
Single Word DMA Mode 2
Multi-Word DMA Mode 1
Multi-Word DMA Mode 2
These devices will be accessed by the driver in either a bus mastering or a
PIO-fashion, depending on the specific transfer conditions.
Devices that do not support the DMA timing modes listed above, or whose PIO
timings are faster than their DMA timings, will be accessed in a PIO-fashion
ONLY.
For more information and a list of tested devices, see the REL_OS2.TXT file.
****************************************************************************
* TROUBLESHOOTING *
****************************************************************************
Common Problems:
****************
1. Some ATAPI CD-ROM devices require vendor-specific filter drivers. These
drivers should be loaded in conjuction with the PIIX Bus Master IDE
driver.
2. Verify the length of the cables that are being used to connect the IDE or
ATAPI devices to the primary and secondary PIIX IDE interfaces. The
length of these cables from END-TO-END should not exceed 18 inches
(0.46 m). Furthermore, the capacitance of the cable should not exceed
35 pF.
****************************************************************************
* IDENTIFYING THE DRIVER'S VERSION NUMBER *
****************************************************************************
The following procedure uses the SEEVER.EXE utility to identify the version
number and build date of the PIIX Bus Master IDE driver. This procedure
assumes that the SEEVER.EXE utility and the driver file (PIIXIDE.ADD) are in
the same working directory.
1. From within OS/2, open the folder containing the PIIX Bus Master IDE
driver.
2. Double click on the SEEVER.EXE icon.
