NOTE: if you are in need of technical help, it is best to FAX us 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.

September, 1993

Updated the MiniSCSI T348 and T358 .ADDs for IBM ThinkPad 720.
The ThinkPad 720 has eliminated all the processor wait states and this
makes the transition times on the parallel port too fast to latch to.
You can make the 720 work by slowing it down to 25MHz, or by using the
new .ADD driver with a /M84 command line option.  This forces a special
mode for the 720 parallel port and adds 4 delay 'ticks' on the T358.
This works with OS/2 2.1 and the ThinkPad 720c in our testing.
The T348 just needs the /M80 command line switch.

July 28, 1993

Tested with OS/2 2.1 GA.  Following the installation instructions
supplied by IBM on page XVIII of their Install guide, everything
installs fine!

Updated drivers to support all mode select commands to make Photo CD
work with OS2CDROM.DMD correctly.

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.




June 25, 1993

Added the T160 driver for the T160/T260 16 bit SCSI adapters.

Additional modifications to the T358 driver to allow for parallel port
speed changes.  Now the /Mnm options explained in the T358 manual will
also work with OS/2.  If you are having trouble getting the T358 to work
with your SCSI device, try adding the command line option /m5 to add
some delays to the T358 operation.  Section 8 of the T358 MiniSCSI EPP
manual discusses these options at length.


May 6, 1993

Changes:

The May 1 beta release wouldn't handle removable media correctly.  This
has been fixed.


May 1, 1993

These drivers are for Trantor T128, T228, T338 , T348 and T130B SCSI
host adapter cards and OS/2 2.0 and 2.1.  OS/2 1.3 is not supported.

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.


MANUAL INSTALLATION for OS/2 2.0 and OS/2 2.1 using OS2CDROM.DMD

The desired driver must be copied to the OS/2 2.1 directory:

    COPY A:*.* C:\OS2

This driver should be installed in the config.sys file as follows:

    ....
    IFS=C:\OS2\CDFS.IFS /Q                      <=== CD-ROM only
    BASEDEV=TxxxSCSI.ADD                        <=== Trantor OS/2 driver
    BASEDEV=OS2DASD.DMD                         <=== for HD
    BASEDEV=OS2CDROM.DMD                        <=== CD-ROM only
    BASEDEV=NECCDS1.FLT                         <=== For NEC CD-ROM only
    BASEDEV=OS2SCSI.DMD                              (other .FLT files
                                                      for other drives)
    ....
where xxx stands for the adapter type: 128, 13B, 338, 348. 

OS2CDROM.DMD and the appropriate .FLT files are supplied by IBM for
CD-ROM support under OS/2 2.1.

All of the above drivers are necessary for CD and HD support. They
should be inserted in your CONFIG.SYS.  Some of these drivers
might already be in your CONFIG.SYS file.  All drivers except for
TxxxSCSI.ADD are usually placed in the OS2 directory during the initial
OS2 installation.



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.


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

T128 jumper settings

Some OEM manuals don't have the jumper settings of the T128 card in
their manual.  For the T128 card, place a jumper shorting pin on JP1:
          ______
IRQ3     | .  . |.  .  .  .
         |______|
        1  .  .  .  .  .  .


IRQ5       .  .  .  .  .  .
          ______
         | .  . |.  .  .  .
        1|______|


IRQ7       .  .  .  .  .  .
             ______
           .| .  . |.  .  .
         1  |______|
