7.1 Introduction
The PPC-153 has an onboard AGP flat panel/VGA interface. The
specifications and features are described as follows:
7.1.1 Chipset
The PPC-153 uses a Lynx 3DM8 SMI 721 chipset from Silicon Motion
Inc. for its AGP/SVGA controller. It supports many popular LCD, EL,
and gas plasma flat panel displays and conventional analog CRT
monitors. The SMI 721 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.
7.1.2 Display memory
With onboard 8 MB display memory, the VGA controller can drive CRT
displays or color panel displays with resolutions up to 1280 x 1024 at
16 M colors.
7.1.3 Display types
CRT and panel displays can be used simultaneously. The PPC-153 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, contact Silicon Motion Inc. or our sales representa-
tive for detailed information.
