 2.0 COMPATIBILITY

  _____________


  This graphics accelerator driver is compatible with

  OS/2 2.1, 2.11, and OS/2 Warp 3.


 3.0 PRELIMINARY STEPS

  _________________


  The following steps prepare your computer for the

  Cirrus Logic device driver:


  1.  You must have OS/2 DOS Support installed in order

      to install this driver.

  2.  If you previously installed SVGA support, return

      to VGA resolution using the procedures in

      "Setting Your Display to VGA Mode" later in this

      README before you install this driver.



 4.0 INSTALLATION FROM DISKETTE

  __________________________


  To install the Cirrus Logic device driver from

  diskette, do the following:


  1.  Insert the Cirrus Logic diskette into drive A (or

      any other diskette drive).

  2.  Open an OS/2 full-screen or OS/2 window session.

  3.  At the OS/2 command prompt, type the following

      command to copy all necessary files to the OS/2

      drive:


             A:SETUP A: C:


      (where A: is the diskette drive, and C: is the

      drive where OS/2 is installed.)


      Then press Enter.

  4.  When prompted to do so, remove the diskette from

      drive A, perform a shutdown, and then restart

      your computer.

  5.  Open the OS/2 System folder.

  6.  Open the System Setup folder.

  7.  Open the Display Driver Install object.

      When the Display Driver Install window appears,

      select Primary Display Driver and then select OK.

  8.  When the Display Driver Select window appears,

      select "Cirrus Logic 5430, 5434 (IBM BBS)"

      to install the BBS video driver.

  9.  When the Monitor Configuration/Selection Utility

      window appears, the "Install Using Defaults for

      Monitor Type" choice is preselected.  You can

      accept this choice or select "Install Using

      Display Adapter Utility Program" to choose a

      different refresh rate.  Then select OK.

      If you select the "Install Using Display Adapter

      Utility Program" choice, you must have a DOS

      monitor utility that came with your display

      adapter.  Contact the display adapter

      manufacturer's technical support for information

      on how to use the monitor utility under OS/2.


      NOTE:  At this point, DSPINSTL determines the

             hardware configuration by creating the

             \OS2\SVGADATA.PMI file.  If the

             \OS2\SVGADATA.PMI file has not been

             created, the adapter will not be

             supported.  This process can take

             several seconds and will black-out the screen.


  10. When the Source Directory pop-up window appears,

      insert the Cirrus Logic diskette into drive A.

      Then select Install.

  11. When the installation is complete, do the

      following:

      a.  Open the OS/2 System folder.

      b.  Open the System Setup folder.

      c.  Open the System object.

      d.  When the Settings notebook appears, select

          the Screen tab.  Then go to Screen page 2.

      e.  On Screen page 2, select your display from

          the display list.  If your display does not

          appear in the list, select Default.

      f.  Return to Screen page 1 and select a screen

          resolution and a screen refresh rate.

      g.  Close the Settings notebook.

      h.  Perform a shutdown and restart your computer.


  Note that during the installation of this driver,

  DISPLAY.LOG and DSPINSTL.LOG files are created in the

  OS2\INSTALL directory.  These files identify the OS/2

  system files that were updated and indicate whether

  the installation was successful.  The contents of

  these files might be useful if you need to report an

  installation problem to IBM.



 5.0 INSTALLATION IN A CID ENVIRONMENT

  _________________________________


  NOTES:


  1.  The server must contain a directory named

      CIR_DRVS on the same drive where the OS/2

      diskettes reside.  The CIR_DRVS directory must

      contain all of the files from the Cirrus Logic

      device driver diskette.

  2.  OS/2 must have been successfully installed on the

      client using the CID (Configuration Installation

      Distribution) method.


  To install the Cirrus Logic device driver using CID,

  use the following information to modify your LCU

  command file.


  NOTE:  The following information is meant as a guide.
