4.1Introduction
The CPC-2520 has an on-board PCI flat panel/VGA interface. The specifications and features are described as follows:
4.1.1 Chipset
The CPC-2520 uses a C&T 69000/69030 chipset for its PCI/SVGA controller. It supports many popular LCD, EL, and gas plasma flat panel displays and conventional analog CRT monitors. The 69000/69030 VGA BIOS supports monochrome LCD, EL, color TFT and STN LCD flat panel displays. In addition, it also supports interlaced and non-interlaced analog monitors (color and mono-chrome VGA) in high-resolution modes while maintaining complete IBM VGA compatibility. Digital monitors (i.e. MDA, CGA, and EGA) are NOT supported. Multiple frequency (multi- sync) monitors are handled as if they were analog monitors.
4.1.2 Display memory
With on-board 2 MB display 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 for true-color resolution of 1024 x 768 with C&T 69030.
4.1.3 Display types
CRT and panel displays can be used simultaneously. The CPC-2520 can be set in one of three configurations: on a CRT, on a flat panel display, or on both simultaneously. The system is initially set to simultaneous display mode. The utility disks includes three *.COM files in the subdirectory Utility\vga\ which can be used to configure the display. In order to use these configu- ration programs, type the file name and path at the DOS prompt.
CT.COM: Enables CRT display only
FP.COM: Enables panel display only
SM.COM: Enables both displays simultaneously
