Chapter 5 PCI SVGA Setup
5.1 Introduction
The board has an onboard AGP flat panel/VGA interface. The specifica-
tions and features are described as follows:
5.1.1 Chipset
The board uses a VIA VT8606 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 VIA VT8606 VGA
BIOS supports color TFT and DSTN LCD flat panel displays. In addi-
tion, 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 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 board 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. If you want to enable the CRT display only or the flat panel display
only, please contact VIA Technology Inc., or our sales representative for
detailed information.
