Chapter 5  PCI SVGA Setup
5.1  Introduction
The PCI-6871 has an onboard AGP flat panel/VGA interface. The speci-
fications and features are described as follows:
5.1.1  Chipset
The PCI-6871 uses a VIA TwisterT 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 TwisterT 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 PCI-6871 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.
