            Trantor Systems OS/2 driver installation
                       for OS/2 2.0

                For the T128, T128F, T228, T130B, 
       T338 MiniSCSI and T348 MiniSCSI Plus SCSI adapters.


For OS/2 2.1 installation, please see the OS/2 Install Guide, Page XVIII

The drivers supplied by Trantor are called Adapter Device Drivers
(.ADD).  They provide an interface between the Trantor SCSI hardware and
the OS/2 operating system.  Support for different SCSI devices is not
done by Trantor, but by IBM with their OS/2 high-level drivers.

In order to use a Trantor SCSI adapter with OS/2, you must first install
the OS/2 SCSI support, the DASD support for hard disk drives, and the
CD-ROM support for CD-ROM drives.  These drivers are included with OS/2,
but were probably not installed when you first set up OS/2 on your
computer.  DOS support is usually automatically installed in the
\os2\mdos directory, so you will see the virtual device drivers in that
directory (VCDROM.SYS, etc).  Do not delete these files if you want to
use DOS as well.

To install the IBM-supplied CD-ROM support drivers on a running OS/2
system, you need to click on the SYSTEM SETUP icon in the OS/2 SYSTEM
folder.  Click on the SELECTIVE INSTALL icon and select OK from the
first screen.  A second screen of options will appear.  For CD-ROM
select the first option, CD-ROM Device Support and then click on the
MORE button associated with this choice.  Check both the CD-ROM IFS and
IBM CD-ROM Device Drivers check boxes and then OK, and proceed with the
installation.

IFS=c:\os2\cdfs.ifs                <-- This is the CD-ROM file system
BASEDEV=os2dasd.dmd                <-- This is the hard disk driver
BASEDEV=os2cdrom.dmd               <-- This is the CD-ROM driver
BASEDEV=xxxxx.flt                  <-- Add the appropriate .FLT file
                                        here for your CD-ROM drive!
BASEDEV=os2scsi.dmd                <-- This is the SCSI driver
BASEDEV=TxxxSCSI.ADD               <-- This is the Trantor driver

Every device connected to the Trantor SCSI adapter has to have, in
addition to the Trantor .ADD, the IBM SCSI driver (OS2SCSI.DMD), the
File System driver (CDFS.SYS for CD-ROM, HPFS.IFS for HPFS partitions,
etc.), and the media support driver (OS2DASD.DMD for Hard Disks,
OS2CDROM.DMD for CD-ROM drives, etc.).

If any of these three levels is missing, your installation won't work!

The order of the files usually doesn't matter, but if you are having
trouble, put the files in the order shown above, with the IFS files at
the beginning of your CONFIG.SYS and the rest of the files at the end of
the CONFIG.SYS.  We've found this always works for us!


CD-ROM drive support with CDROM.SYS from IBM

The Trantor OS/2 .ADD driver has a command line switch documented in the
README.DOC file that comes with the TxxxSCSI.ADD driver. If you add the
/T command line option to our .ADD, all CD-ROM drives then look to the
IBM CD-ROM.SYS driver as though they were an IBM drive.  This will allow
data reads on all CD-ROM drives, but will not support audio commands.  A
special version of OS2CDROM.DMD with the appropriate .FLT file is needed
to support audio commands on non-SCSI-2 drives.
Do NOT use the /I parameter on the IBM CDROM.SYS file in your
CONFIG.SYS.


CD-ROM drive support with OS2CDROM.DMD and xxxxxxx.FLT files from IBM

With this new driver (Available from IBM or on GEnie or Compuserve's
OS/2 Forum) you need to make sure there is no /T option after the
Trantor .ADD.  Follow the instructions that come along with the
OS2CDROM.DMD file and replace CDROM.SYS with the .DMD file and the
appropriate .FLT file references for the CD-ROM drive you are using.


Removable Media Drives (Syquest, Bernoulli, etc.)

IBM treats removable media drives as though they are a very large
floppy.  This means you can't necessarily interchange removable media
between DOS and OS/2.

To format a removable media drive for OS/2, you first have to do a low
level format under MS-DOS with the TFORMAT utility.  Select a single
partition... the IBM driver can't handle multiple partitions on
removable media.

Boot up your OS/2 system with this formatted cartridge in the drive.
From the OS/2 SYSTEM folder, select the DRIVES icon and double click on
it.  Select the removable media drive (which will show up with a floppy
icon) and click the center button.  Select FORMAT DISK and use any
available capacity... 2.88M will work just fine.  The removable media
drive will be formatted to its correct capacity with an OS/2 partition.
You can now use the drive cartridge under OS/2.  It may not be readable
by an MS-DOS system.


Setting up a Hard Drive for OS/2 use

If you have an existing hard disk drive on your TRANTOR SCSI controller
set up as a single partition under MS-DOS 4.01 or 5.0, you should be
able to install it under OS/2 with no special requirements other than
those discussed here earlier.

If you have a disk partitioned under DOS 3.3 larger than 32M, you will
need to re-format your disk under DOS 4.01 or later for OS/2, since
partition sizes over 32M are non-standard.  Warning - - All your data
will be lost if you format your disk drive unless you back it up first!

To format your hard disk drive, you must run the DOS-based TFORMAT
program supplied with the Trantor SCSI adapter.  There is no OS/2
version of this program, but it will run from a DOS box or VDM on your
OS/2 system.

In order to make the Trantor SCSI adapter a primary OS/2 boot drive, you
must have an optional BIOS ROM package called a T2ROM. T128 and T228
cards are not shipped with this ROM package... they use a different
version of the Boot ROM.  The T2ROM for the T128 may be ordered from the
Trantor sales office.  T130B cards come standard with the T2ROM BIOS ROM
installed.  The T2ROM is also supported with the IBM generic INT13
driver that is included with OS/2 and can be installed in your OS/2
system.

Error Messages


The System cannot find the file "C:\OS2\SYSTEM\COUNTRY.SYS" specified in
the COUNTRY command... The System is stopped.

        This error usually happens if the OS2DASD.DMD driver is not
        installed in the CONFIG.SYS.  Make sure you have
        BASEDEV=OS2DASD.DMD in the CONFIG.SYS right after the
        BASEDEV=IBM1FLPY.ADD statement.  If you installed the SCSI
        support on the OS/2 Installation, you should not get this
        message.

        This can also happen if you install OS/2 on a second partition
        of your C: drive and add a second SCSI hard drive for OS/2.
        OS/2, like MS-DOS, always mounts first partitions on hard drives
        before extended partitions.  OS/2 will assign a second drive a
        drive letter D: and the second partition on the original C:
        drive will become E: rather than the D: it was without the
        second drive attached. OS/2 can't load files from the D: drive,
        since it is now re-assigned as E:.  Since OS/2 always tries to
        load COUNTRY.SYS, it errors out at this point.  You can change
        the drive that the OS/2 files are loading from to fix this
        problem.


SYS1718: The System cannot find the file "...  "

        The file indicated has not been installed.  Most commonly
        happens when CD-ROM files are not copied to the System
        subdirectory.  Use the OS/2 Selective Install program to install
        your CD-ROM support files.


SYS1201: The device driver "C:\OS2\CDROM.SYS" specified in the DEVICE
command on line... was not installed.  Line is ignored.

        The .ADD driver for the SCSI adapter didn't load.  Either there
        is not SCSI device attached, the SCSI adapter isn't installed,
        or there is a hardware conflict with the SCSI adapter.  Check
        under DOS with SCSITEST to see if the SCSI device is identified.


SYS1201: The device driver "TxxxSCSI.ADD" specified in the BASEDEV=
command on line... was not installed.  Line is ignored.

        The .ADD driver for the SCSI adapter didn't load.  If you are
        using a MiniSCSI adapter, make sure the SCSI device is plugged
        in and powered up correctly.  Check your installation under DOS
        and with SCSITEST to see if the SCSI device is indentified
        correctly.  With a bus-based adapter and an internal drive,
        check that the ribbon cable is not on backwards and that the
        SCSI adapter is actually installed in the computer.
