A. Installation procedure for PM:

    1. While installing OS/2, when a prompt for other device support comes,
       select "YES", and insert the CornerStone PM Driver diskette.

       Install CORNERSTONE VIDEO DRIVER & 
	       CORNERSTONE PM DRIVER.



B. Support for multiple video:


   I.  To support multiple video controller please make following changes to
       your CONFIG.SYS file:

       1. Search your config.sys file for "BVHMPA", if it is there
          you are done. Skip to step "C".

       2. Append the ",VIO_OTHER_BVH" string to the end of SET VIDEO_DEVICE.
       
       3. Edit the next line to SET VIDEO_DEVICE and modify the "DEVICE(?)"
          to "DEVICE(BVHMPA)

       4. Insert a line:

	  SET VIO_OTHER_BVH=DEVICE(?)

	  where "?" is the string before the SET VIDEO_DEVICE line was 
	  modified.


Example:
	Let your config.sys look like:


		SET VIDEO_DEVICES=VIO_IBMEGA
		SET VIO_IBMEGA=DEVICE(BVHEGA)


	After following above steps:


		SET VIDEO_DEVICES=VIO_IBMEGA,VIO_OTHER_BVH
		SET VIO_IBMEGA=DEVICE(BVHMPA)
		SET VIO_OTHER_BVH=DEVICE(BVHEGA)




   II. Copy A:\BVHMPA.DLL C:\OS2\DLL\BVHMPA.DLL




C. No of planes to use:

   Suppose your CornerStone video controller has more than one plane, and
   you want to use only one plane or two plane only, then change the 
   config.sys.

     Append a strings to
        C:\CVC.SYS
       "-p?" where as "?" is 1 or 2.

     After the above change the line should read
        C:\CVC.SYS -P1.
