®
VGA display standard
•
32-bit video memory access with 1 MB, 50 ns, EDO, video DRAM.
Increased to 64-bit access when an additional 1 MB DRAM is installed
•
integrated 24-bit RAMDAC
•
fully programmable Pixel Clock Generator up to 170 MHz
•
60 MHz clock for video memory
•
fast linear addressing with full software relocation
•
green power saving features
•
playback acceleration, continuous interpolation on X, continuous interpo-
lation on Y
•
DDC 2B compliant.
Video Memory
1 MB is fitted as standard. Two sockets are provided for installation of an
additional 1 MB (two modules, each with a 512 KB, 60 ns surface mount
chip). The installed video memory capacity is detected automatically by the
BIOS.
The controller gives 32-bit video memory access, with 1 MB of video RAM
fitted. This is increased to 64-bit access when the additional 1 MB upgrade is
installed.
There is no orientation key to determine the polarity of the upgrade chips,
so care must be exercised to align the point on the chips with the cut edge
of the socket. A special extraction tool (5041-2553) is needed when
removing them again.
