SCO Boot Time Loadable DPT RAID Driver

Installation of the DPT RAID device driver is a simple procedure that can be
performed either as a "Boot Time Loadable Driver (BTLD)" or as a driver
installed into an existing system. The same installation floppy will be
used for both types of installations. The only time that you would need to
install the driver as a BTLD is if you configured the "boot" device as a
software RAID 0 LSU. In all other cases & when the RAID 0 LSU is a
secondary device, the installation should be done after the system is
installed and running.

Installing As A Boot Time Loadable Driver (BTLD) for SCO 3.2.4.2/ODT 3.0:

1)     Insert the standard SCO N1 boot floppy into the drive
       and power on the system.

2)     At the "Boot:" prompt, enter the string :

             defbootstr disable=dpt link=dptr4

             and press Enter.

3)     The system will load the Unix kernel from the N1 floppy
       and then prompt you to insert the dptraid installation
       floppy. Insert the floppy and press Enter. The system
       will copy the necessary object files from the floppy
       and link them into the Unix kernel.

4)     Next you will be asked to insert the N2 floppy. When
       you press Enter, the Unix kernel will boot. During the
       SCO Unix Hardware Roster Screen, a line similar to the following
       should appear:

             "%adapter type=dptr ha=0 id=7 Bus Master"

5)     From here on you should go through a normal SCO UNIX
       installation as outlined in the DPT Manual. At some
       point in the installation you will be prompted to
       insert the dptraid install disk again. All of the
       necessary files will be copied off of the disk and
       stored in memory. Near the end of the installation
       when the install script is setting up the link kit for
       the currently installed hardware configuration, you
       will be prompted to install the dptraid driver into
       the link kit.

             NAME       DESCRIPTION
             dptr4      A DPT RAID SCSI Host Adapter Driver

             Please enter the names of the packages you
             wish to install, or q to quit:

             type dptr4 and press Enter. The DPT RAID driver will
             be installed and a new Unix kernel will be built and
             installed.

Installing into an up and running system for SCO 3.2.4.2/ODT 3.0:

1)     At the Unix prompt Enter the command installpkg and
       press Enter. You will be prompted to insert a disk.
       Insert the dptraid install disk and press Enter.

2)     you will be prompted with:
             The following packages are on this disk:

             NAME       DESCRIPTION
             dptr4      A DPT RAID SCSI Host Adapter Driver

             Please enter the names of the packages you
             wish to install, or q to quit:
             type dptr4 and press Enter

3)     The installation package will turn off the original
       DPT driver and install the new DPT RAID Driver.

4)     A new Unix kernel must be built and installed before
       the new driver be accessed.


Installing As A Boot Time Loadable Driver (BTLD) for SCO Open Server 5

1)     Insert the standard SCO N1 boot floppy into the drive
       and power on the system.

2)     At the "Boot:" prompt, enter the string :

             defbootstr ahslink=dptr5

             and press Enter.

       Shortly after pressing enter, SCO UNIX will display the
       prompt "Add, Replace, or Do Nothing" indicating that it
       found the existing embedded DPT driver.  At this prompt
       enter "25" and press enter to instruct SCO UNIX to
       replace the existing embedded driver.
     

3)     The system will load the Unix kernel from the N1 floppy
       and then prompt you to insert the dptraid installation
       floppy. Insert the floppy and press Enter. The system
       will copy the necessary object files from the floppy
       and link them into the Unix kernel.  During the SCO UNIX
       Hardware Roster Screen, a line similar to the following
       should appear:

             "%adapter type=dptr5 ha=0 id=7 Bus Master"

4)     From here on you should go through a normal SCO UNIX
       installation. At some point in the installation you
       will be prompted to insert the dptraid install disk
       again. All of the necessary files will be copied off
       of the disk and stored in memory. Near the end of the
       installation when the install script is setting up the
       link kit for the currently installed hardware configuration,
       you will be prompted to install the dptraid driver into
       the link kit.

             wish to install, or q to quit:

             type dptr5 and press Enter. The DPT RAID driver will
             be installed and a new Unix kernel will be built and
             installed.

       press Enter. You will be prompted to insert a disk.
