Installing Video 7-1
SECTION 7
INSTALLING VIDEO
The VIPer808 video system includes a local bus CRT video controller and 1MB of video
memory (optional 512KB).
7.01 CRT SVGA CONTROLLER
The VIPer808's CRT Super VGA controller is a single-chip video controller from Cirrus
Logic
(CL-GD5429). It is fully compatible with the IBM
VGA standard at the
hardware and BIOS level.
7.01.1 CRT SUPPORT
The video controller supports both monochrome and color VGA/SVGA displays with
resolution of up to 1280 x 1024 (256 colors). However, since the video controller outputs
only analog signals for CRT display, it will not drive TTL level signals. This means it
does not function with CGA, EGA and Hercules monitors.
7.01.2 DISABLING VIDEO
The video controller can be disabled by removing the W4 jumper. See Section 3 for
jumper location and settings.
This feature is useful when an external video card is required for testing or other purposes.
