5.1 Introduction

The PCM-9574 has an on-board PCI flat panel/VGA interface. The
specifications and features are described as follows:

5.1.1 Chipset

The PCA-9574 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-9574
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."
