PCM-9575 User’s Manual 46
Chapter 5 PCI SVGA Setup
5.1 Introduction
The PCM-9575 has an onboard AGP flat panel/VGA interface. The spec-
ifications and features are described as follows:
5.1.1 Chipset
The PCM-9575 uses a VIA Twister 8606T chipset from VIA Technology
Inc. for its AGP/SVGA controller. It supports many popular LCD, and
LVDS LCD displays and conventional analog CRT monitors. The
VIA8606T VGA BIOS supports color TFT and DSTN 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
The Twister chip can support 8/16/32MB frame buffer shared with sys-
tem memory; the VGA controller can drive CRT displays or color panel
displays with resolutions up to 1280 x 1024 at 16 M colors.
5.1.3 Display types
CRT and panel displays can be used simultaneously. The PCM-9575 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 dis-
play mode. If you want to enable the CRT display only or the flat panel
display only, please contact VIA Technology Inc., or our sales representa-
tive for detailed information.
