Introduction

The PCM-5820 Series has an on-board LCD/VGA interface. The
specifications and features are described as follows:

5.1.1 Chipset

The PCM-5820 Series uses a Cyrix CX5530 chipset for its SVGA
controller. It supports many popular 18-bit LCD displays and
conventional analog CRT monitors. The VGA BIOS supports
LCD. In addition, it also supports interlaced and non-interlaced
analog monitors (color and monochrome VGA) in high-resolution
modes while maintaining complete IBM VGA compatibility.
Digital monitors (i.e. MDA, CGA, and EGA) are NOT supported.
Multiple frequency (multisync) monitors are handled as if they
were analog monitors.

5.1.2 Display memory

With 2 ~ 5 MB share memory, the VGA controller can drive CRT
displays or color panel displays with resolutions up to 1024 x 768
at 64 K colors. The display memory can be expanded to 4 MB in
BIOS for true-color resolution of 1024 x 768.
