What does the acronym EGA stand for Enhanced
Graphics Array.
In the 640×350 high resolution mode, each of the
sixteen colors can be selected from a palette comprising all possible
combinations of two bits per pixel each for red, green and blue, allowing four
levels of intensity for each primary color and sixty-four possible colors
overall. EGA also includes full sixteen-color versions of the CGA 640×200 and
320×200 graphics modes; only the sixteen CGA/RGBI colors are available in these
modes[citation needed]. EGA four-bit (sixteen colors) graphic modes are also
notable for a sophisticated use of bit planes and mask registers
EGA produces a display of sixteen simultaneous
colors from a palette of sixty-four, at a resolution of up to 640×350 pixels.
The EGA card includes a 16 KB ROM to extend the system BIOS for additional
graphics functions, and includes a custom CRT controller (CRTC) that has
limited backward compatibility with the Motorola MC6845 chip used to generate
video timing signals in earlier IBM PC graphics controllers.[6] The EGA CRTC
can support all of the modes of the IBM MDA and CGA adapters, partially through
specific mode options intended for this purpose,
EGA cards use the PC ISA bus and were available
starting in both eight- and sixteen-bit versions. The original IBM EGA card had
64 KB of onboard RAM and required a daughter-board to add an additional 64 KB
(cards with 64 KB are limited to four colors when 640×350 mode is used). All
third-party cards came with 128 KB already installed and some even 256 KB,
allowing multiple graphics pages,
