OS/2 Read Me file
These drivers are Copyright 1994 by Trantor Systems Limited. All rights
reserved. They may be freely distributed to owners of Trantor products
as long as this documentation file is included with the files.
AUTOMATIC INSTALLATION
Copy all the files to a floppy. This floppy is now a device support
diskette. Insert it in A: and run DDINSTAL from the OS/2 prompt. The
Device Driver Install icon can be found by selecting the OS/2 System
icon on the desktop, then the System Setup icon in that window. Insert
your floppy in a disk drive and double click on the Device Driver
Install icon.
The OS/2 .ADD driver we supply is fully compatible with any driver that
interfaces with the .ADD specification for OS/2 2.0. It will work
transparently with any hard disk supported by OS/2.
NOTE: if you are in need of technical help, it is best to FAX a copy
of your CONFIG.SYS. Most problems can only be found after looking at
this file carefully. It is almost impossible to troubleshoot over a
voice call without the CONFIG.SYS in front of a technician.
Tested with OS/2 2.1 GA. Following the installation instructions
supplied by IBM on page XVIII of their Install guide, everything
installs fine!
To enable interrupts in any driver, use the command line option /Ixx,
where xx is the IRQ you require. Make sure you jumper the IRQ on the
SCSI adapter as appropriate. If you select an IRQ that doesn't exist,
the .ADD will automatically poll instead of using an IRQ.
OPTICAL DRIVES:
IBM supplies a driver called OPTICAL.SYS for use with their 3.5"
Magneto-Optical drive and other Magneto-Optical drives. We have
confirmed that it works correctly with this .ADD release.
In addition, we have implemented an optional command line switch that
will enable some Magneto-Optical drives to be treated like a hard drive
when OPTICAL.SYS is not available. Adding the command line parameter of
/o to the .ADD driver forces the operating system to treat an MO drive
as a standard hard drive.
CD-ROM DRIVES:
OS/2 2.1 OS2CDROM.DMD
Various .FLT files are available to provide support for non SCSI-2
drives. These are provided by IBM along with the OS2CDROM.DMD driver.
In order to have a CD-ROM drive show on your desktop with a CD-ROM icon,
you must have a CD-ROM disc in your drive when the system is booted. If
you boot with an empty CD-ROM drive, the drive icon will appear as a
floppy disk instead of a CD-ROM disc. This will not affect the
operation of the CD-ROM drive itself.
If you have a CD-ROM drive with multiple Logical Units (LUNs), like the
Pioneer DRM-600, you will be able to access all Logical Units with the
August, 1992 driver. To restrict the number of logical units, the /U
command line parameter can be used to recognize only 1 Logical Unit of
the possible 6 in the DRM-600. This command line switch also works with
hard disk drives that incorrectly report LUNs.
HARD DISK DRIVES
Format the SCSI device first from DOS with the TFORMAT program that
comes included with the Trantor SCSI adapter. Select a single partition
after low level formatting the drive.
Boot OS/2 with the drivers installed and format the disk with the OS/2
formatter.
We have found removable media must be formatted with the OS/2 format
program before it can be recognized. Just format it as though it is a
floppy... selecting a 2.8M floppy, for instance, formats a Syquest
drive to 42M just fine. Removable media drives are not interchangeable
between DOS and OS/2.
NOTES:
- Removable media is supported. It was tested with a SyQuest drive.
- OPTICAL.SYS provided by IBM will support MO drives.
- option /o supports MO drives by treating them like HD's.
- option /u restricts the number of Logical Units. Default is 7
- option /ixx allows setting the interrupt level in the driver,
where xx is the unique IRQ you want to use
