5.1 Introduction

The PCM-9570/S has an on-board PCI flat panel/VGA interface. The specifications and features are described as follows:

5.1.1 Chipset

The PCA-9570/S uses a Trident 9525DVD chipset for its PCI/SVGA controller. It supports many popular LCD, EL, and gas plasma flat panel displays and conventional analog CRT monitors. The 9525 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 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 display memory on board, the VGA controller can drive CRT displays or color panel displays with resolutions up to 1024 x 768 at 16.8 M colors. You have the option to use the Trident 9525 to expand the display memory to 4 MB (TM 9540 chip). This yields true-color resolution of 1280 x 1024.

5.1.3 Display types

CRT and panel displays can be used simultaneously. The PCA-9570/ S 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 BIOS setup can be used to configure the display. In BIOS, select “Integrated Peripherals”, then “Boot-up display type.” You can then choose one of the following modes: “CRT only”, “Panel only”, or “Simultaneous.”
