  |    UNIX Driver V1.31 for DC-200/DC-4030VL/DC-4030VL-X/DC400/DC-5030    |
  +========================================================================+


     ******** Install UNIX Driver  ********

     This driver is for AT&T UNIX SVR 4.0 and SCO UNIX 3.2.X. The driver
     is provided on another diskette of your 
     DC-200/DC-4030VL/DC-4030VL-1/DC-4030VL-2/DC400/DC-5030 package. Please 
     follow the steps below to install the UNIX driver:

      1. If you are running SCO UNIX, and 
	 
	1.1 If your diskette is inserted in diskette drive A:, 
      	    please type the following commands to copy 
	    the installation shell script from diskette to hard disk.

	   # cd /tmp
	   # doscp a:/unix/ptiinst .
	   # sh ./ptiinst a:

	1.2 If your diskette is inserted in diskette drive B:, 
      	    please type the following commands to copy 
	    the installation shell script from diskette to hard disk.

	   # cd /tmp
	   # doscp b:/unix/ptiinst .
	   # sh ./ptiinst b:
	

      2. If you are running AT&T UNIX SVR 4.0, and 
	 
	2.1 If your diskette is inserted in diskette drive A:, 
      	    please type the following commands to copy 
	    the installation shell script from diskette to hard disk.

	   # cd /tmp
	   # doscp -m a:/unix/ptiinst .
	   # sh ./ptiinst a:

	2.2 If your diskette is inserted in diskette drive B:, 
      	    please type the following commands to copy 
	    the installation shell script from diskette to hard disk.

	   # cd /tmp
	   # doscp -m b:/unix/ptiinst .
	   # sh ./ptiinst b:
	

      3. During installation, it will ask another blank diskette.
	 Please insert that diskette as requested. 

      4. The system will ask you for the IRQ of the secondary hard
	 disk controller by the following question:
 
	    If you will install one DC-200/DC-4030VL-1/DC-4030VL-2/DC-5030
	    controller as the secondary hard disk controller, 
	    what is the IRQ of the secondary hard disk controller
	    in this system (12 or 15)? (default=15)

	 Please choose the appropriate one according to the jumper setting
	 of that DC-200/DC-4030VL-1/DC-4030VL-2/DC-5030 controller.

      5. The following message will be displayed on the screen:
	
	    Does the mainboard CPU have a 16-bit external data bus
	    (for examples,IBM 486 SLC2 ...) instead of a 32-bit bus 
	    (Y/N)? (default=N)

         Please answer 'Y' or 'N' to fit your mainboard CPU.

      6. Done! if you are running AT&T UNIX SVR 4.0.

      7. If you are running SCO UNIX, type the following commands after
	 the driver is installed.

            # cd /
            # shutdown -y -g0 -i6

         The commands will shutdown and reboot your system with the new kernel.

      NOTICE:
       1.) Primary controller means the hard disk controller with 
	   IRQ 14, and secondary controller is the hard disk 
	   controller with IRQ 12 or 15. 
       2.) If you will install two DC-200/DC-4030VL/DC-4030VL-1/DC-4030VL-2
	   /DC-5030 controllers in the same system, please read the following:
    	   . After the machine has been powered on and the controller
	     has checked its memory size, you can press the function 
	     key <F2> to enter the setup menu.  Then, press <F1> to 
	     enter the Set-up Configuration submenu. Now you are ready
 	     to setup the BIOS starting address.
    	   . The BIOS starting address of each Promise controller must 
	     be different.
             For example, you can set one BIOS starting address to be 
             dc000, and another to be c8000.


     ******** Add Secondary Hard Disks *******

     If you have attached more than one hard disk to the cable, you must
     do the following things to make this hard disk "visible" to the system.

     1. Please type the following command:

   	# ptidiskadd 

     2. The command will ask you of the following three questions:

	   Which controller will the hard disk be attached to?

	    1. the primary controller
	    2. the secondary controller

	   Please choose answer(1 or 2)(default=1): 

	   Which cable (of this controller) will the hard disk be attached to?

	    1. the first cable
	    2. the second cable

	   Please choose the answer(1 or 2)(default=1): 

	   Will the hard disk be the master(single) or slave drive on this
	   cable?

	    1. the master or single hard disk
	    2. the slave hard disk

	   Please choose the answer(1 or 2)(default=2):

        Please answer the questions according to your setting.

     4. The other steps are very similar to the procedures about
	"Adding secondary hard disks" presented in the System Administor's
	Guide of SCO UNIX Operating System. Please refer to the System
	Administor's Guide for further reference. 

     NOTICE:
     1.) When using the ptidiskadd, you MUST set the 
	 DC-200/DC-4030VL/DC-4030VL-1/DC-4030VL-2/DC-5030 controller to
         "cache disabled".
         With "cache disabled", the system will be able to identify the
         bad sector of the hard disk.
     2.) This utility will not work until you install the 
	 DC-200/DC-4030VL/DC-4030VL-1/DC-4030VL-2/DC-5030 driver and reboot
         with the new kernel.
     3.) With both primary and secondary 
	 DC-200/DC-4030VL/DC-4030VL-1/DC-4030VL-2/DC-5030 controller
         installed, you can add up to 8 hard disks.


     ******** Remove the Driver ********

     If you want to remove the driver and recover to the original hard disk
     device driver, please type the following command after the prompt #:

            # removepkg

     Certain installed package name(s) will be displayed on the screen.
     Please choose
     "DC-200/DC-4030VL/DC-4030VL-1/DC-4030VL-2/DC400/DC-5030 UNIX Driver".
     The remove procedure will continue.

     If you are running the SCO UNIX, please type the following commands to
     shutdown and reboot your system:

            # cd /
            # shutdown -y -g0 -i6
