4850 EP  (250-5143)           VGA Video                Faxback Doc. # 1014

The video circuitry for your computer is included on the main logic board.
This circuitry features:

* IBM VGA compatibility plus support for Super VGA modes with 132-column text
  and both 800 x 600 and 1024 x 768 resolution graphics.

* Support or VESA Super VGA BIOS Extension Version 1.0 specification

* A color palette of more than 262,000 possible colors

* Compatibility with monochrome and color, fixed-frequency and
  multiple-frequency analog monitors (including 8514/A-compatible monitors)

MONITOR AND SOFTWARE COMPATIBILITY

The video circuitry is compatible with software written for the following
video standards on color or monochrome VGA analog monitors:

* VGA
* VESA Super VGA
* Multi-Color Graphics Array (MCGA)
* Enhanced Graphics Adapter (EGA)
* Color/Graphics Adapter (CGA)
* Monochrome Display Adapter (MDA)
* Hercules graphics (Hercules Graphics Card)

CONFIGURING THE APPLICATION SOFTWARE

Many application packages include a program to prepare them for operation with
your hardware. You can configure many applications without re-installing them.
You can also configure applications during installation.

NOTE: Before installing drivers, make copies of the original Installation
diskettes. The Drivers Diskette must be write-enabled.

The VGA 1024 NI Drivers Diskette contains drivers for many applications. To
install a driver, follow these steps:

1. Insert the Drivers Diskette into Drive A.

2. Type a: and press ENTER.

3. Type install and press ENTER.

4. To view the documentation, type a: and press ENTER, and then type readme
   and press ENTER.

5. To print the documentation, type a: and press ENTER, and then type printme
   and press ENTER.

NOTE: To use the highest resolution VGA modes with several popular
applications, you must use the VGA 1024 NI drivers. Follow the tips below for
best results:

* Video drivers for common applications are included on the Drivers Diskette.
  See the README file included with the drivers and the documentation included
  with the application software.

* To get the sharpest display, select the highest resolution mode available
  when you configure your application software packages.

* Install your software for VGA or EGA if possible. This enables you software
  to run with your video circuitry in its default configuration.

* If your software does not provide a VGA or an EGA option and you are using a
  color monitor, try installing the software for color, if available. This
  usually works with the video circuitry's default mode on color monitors.

* If your software supports a video standard other than EGA or VGA, configure
  the software for the best standard. Run VGAMODE.EXE and set the emulation
  mode to match the program.

OPERATION

The video circuitry, in its default configuration, supports most application
software that is designed for the vGA or EGA video standard. Install the
application as described in the application documentation. On system startup,
the video circuitry automatically configures itself to 80-column text mode.

Connect the monitor to the 15-pin video connector on the back of the computer.
Refer to "Configuration Settings" in the "Installing Optional Hardware"
section for video-related switch settings.
