Your computer’s video and memory features work together for
enhanced performance. Incorporating Wingine technology, the
advanced system architecture allows the CPU to communicate
directly with the video memory, providing direct throughput
from the system memory to the display. Combined with the
speed and graphics capabilities of the Wingine VGA controller,
this technology produces screen refresh rates that are ten times
faster than standard super VGA systems and up to five times
faster than systems that employ “local bus” technology.
Additionally, your computer can use all of its memory as a
virtual cache pool. Unlike most systems that provide only a
64KB or 128KB cache buffer-which typically fills up with the
first or second memory access command-your computer uses
all the RAM as a “virtual” cache buffer. You’ll notice the
improved performance especially when running
memory-consuming graphics programs such as Windows
applications or CAD programs.
Using the built-in interfaces, you can connect your peripheral
devices directly to the computer so you don’t have to install
option cards. You can use the option slots to enhance your
system with extra functions such as a modem card, network
card, or additional interface ports.
VGA
Utilities
Your computer comes with special MS-DOS
®
VGA device
drivers and utilities for use with the integrated VGA interface.
With these utilities, you can take advantage of extended VGA
features such as high resolutions and 132 - column text mode
when you run popular application programs. The Wingine
controller works with the display drivers to provide sharp,
clear resolutions of up to 1024 x 768 for the Windows
environment. See the
VGA Utilities Guide
for installation
instructions.
