2 PCM-3521 User's Manual
Video BIOS
The PCM-3521's hardware supports a wide variety of
flat-panel and analog CRT displays. However, special
software routines and parameters are needed to
interface with any given display. These routines are
stored on the PCM-3521 in a 64 KB ROM BIOS chip.
The high performance CHIPS 65545 VGA, BIOS used
within this unit is optimized for usage with 65545 VGA
Flat-panel/CRT controller chips.
Display support
The 65545 VGA BIOS supports monochrome LCD, EL,
plasme, color TFT and STN LCD flat-panel displays. It is
fully compatible with IBM VGA displays - even with
interlaced and non-interlaced analog monitors (VGA color
and VGA monochrome) in high-resolution mode. Multiple
frequency (multisync) monitors ar esupported as analog
monitors. Both CRT and panel displays can be used
simultaneously. However, digital monitors, such as
MDA, CGA, EGA are not supported.
Configuration
Although the PCM-3521 is compatibile with many types
of displays, its configuration is quite simple, since
most of the configurations are done in the BIOS setup.
The section describes the hardware settings
necessary to get your display operational. Furthermore,
some of the PCM-3521's special features are given in
this section.
