3.3.2 System Memory

The system memory consists of PC100 SDRAM memory on 64-bit bus and the module size

options are 16/32/64/128MB. PC100 SDRAM synchronizes itself with the CPU bus speed so

if the CPU is set at 100MHz-bus speed, the memory speed is also running at 100MHz. The

BIOS will automatically detect the amount of memory in the system and configure CMOS

accordingly during the POST (Power-On Self Test) process. This is done in a way that

requires no user interaction.

3.3.3 Video

The Video subsystem uses 4 or 8MB of “Shared Memory” from the System Main

Memory. The system supports true ZV port, Microsoft Direct 3D, simultaneous display,

monitor sense for auto display on boot and VESA Super VGA function call.

Supported Video Mode

The following is all the display modes supported by the Trident 8400 in LCD only, CRT

only, and simultaneous mode. The VGA BIOS will allow mode sets of resolutions

greater than the panel size but only show as much mode display as will fit on the panel.
