52 PCM-5820 Series User's Manual
5.1 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 conven-
tional analog CRT monitors. The VGA BIOS supports LCD. In
addition, it also supports interlaced and non-interlaced analog moni-
tors (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.
