* SCO Unix 3.2v4.0 & UnixWare 1.1 (SVR4.2 ver1) drivers:                    *
* unx_390.z  : for DC-390                                                   *
* unx_390w.z : for DC-390W/U/F                                              *
* => The following steps use unx_390.z, i.e., DC-390, as an example. If you *
*    are installing a DC-390W/U/F, replace unx_390.z with unx_390w.z.       *
*****************************************************************************

unx_390.z is a compressed image file of the Unix driver diskette.
In order to install the Unix driver, a 1.44M diskette must be prepared first
from this file. Follow the steps below:

1. Copy this file to a DOS formatted diskette by typing "copy unx_390.z a:"

The following steps must be carried out in Unix. Take SCO Unix 3.2v4 as an
example:

2. In Unix, type "doscp a:unx_390.z unx_390.Z" to copy the image file into
   Unix. (Note: Unix filenames are case-sensitive!)
3. Decompress the image file by typing "uncompress unx_390.Z". This creates
   the unx_390 file.

Now a 1.44M diskette must be prepared. Assume A: is the 1.44M floppy.

4. Insert a diskette in A:.

5. Type "dd if=unx_390 of=/dev/rdsk/f0q18dt"
                                    |______ means drive A:, 1 for B:(f1q18dt)

The Unix driver diskette is now prepared.

* SCO Unix Driver Installation                                              *
*****************************************************************************
Two different installation procedures are described separately. Use the
one that fits your environment:
    <1> SCO UNIX has been installed on a non-SCSI boot drive.
    <2> SCO UNIX is to be installed from scratch on a SCSI drive attached to
        a DC-390 Series adapter.

<1> Driver Installation for an installed SCO UNIX system on a non-SCSI
    boot drive:
    1. Boot SCO UNIX into administration (single user) mode.
    2. It is necessary to make a backup copy of the working UNIX kernel in
       case a hazardous condition should occur after the driver is
       installed and the system is booted from the new kernel:

       cp /unix /unix.ok

    3. Insert the BTLD driver diskette into the floppy drive and start the
       driver installation by typing:

       installpkg

    4. The screen will then show the driver package description similar to
       the following:

       NAME            DESCRIPTION
       tps.pkg         Tekram DC390 PCI SCSI adapter driver(v1.0)
       tpsw.pkg        Tekram DC390WUF PCI SCSI adapter driver (v1.0)

       Go on typing the following command to install the driver:

       tps.pkg         <---- For DC390
       tpsw.pkg        <---- For DC390W/U/F

A series of messages will then be displayed as the procedure is completed.

    5. If any SCSI devices are to be added (it is NOT necessary to have the
       hardware actually connected), now is the proper time to add them.
       (Refer to SCO UNIX administrator's manual for how to add SCSI devices
       to the system).

       Note: It's important that when asked to input the driver prefix, enter
             tpsw (For DC-390W/U/F) or tps (For DC-390) in response, and
             proceed as normal. Or, you can manually edit the SCSI device
             configuration file: /etc/conf/cf.d/mscsi.

    6. After devices are added, rebuild the kernel as instructed. If you do
       not plan to add any device, in order to rebuild the kernel, type the
       following commands:

       cd /etc/conf/cf.d
       ./link_unix

    7. Reboot the system to allow the driver to take effect.


<2> Installation of SCO UNIX along with DC-390/W/U/F adapter and driver:
    1. Insert system diskette N1 and boot from the floppy.

    2. When the boot prompt is shown:
           Boot
           :
       Type the following command to proceed:
           link

    3. When the system asks for the name of the driver package, type
           tps.pkg         <---- For DC390
           tpsw.pkg        <---- For DC390W/U/F

    4. The system will keep on booting from floppy N1 and then request that
       the driver diskette be inserted into the floppy drive. Insert the disk
       as requested. After the driver is successfully loaded, follow the
       normal procedures to install SCO UNIX. In the process of installation,
       the driver diskette may need to be inserted as instructed.

       Once the system reboots with the driver successfully installed, 
       messages similar to the following will be displayed:

   device    address       vector  dma    comment
