Windows device driver information for Intel Corporation Intel740 Graphics Adapter

The Intel Corporation Intel740 Graphics Adapter is the IBM PC computer display standard specification positioned between CGA and VGA in terms of color and space resolution. It was in 1984 by IBM for its new PC-AT. It generates a display of 16 concurrent colors from a palette of 64 at a resolution of up to 640√ó350 pixels. It includes a 16 kilobyte ROM to extend the system BIOS for extra graphics functionalities and includes the Motorola MC6845 video address generator as utilized in the CGA. Each of the 16 colors can be designated to a unique RGB color code through a palette mechanism in the 640√ó350 high-resolution mode. The 64 palette colors are a balanced RGB color set includes of all possible combinations of two bits per pixel for red, green and blue. It also includes full 16-color versions of the CGA 640√ó200 and 320√ó200 graphics modes.

The Intel Corporation Intel740 Graphics Adapter utilizes a female 9-pin D-subminiature connector which appears very much alike to the CGA connector. The hardware signal interface, including the pin setting, is greatly compatible with CGA. The variations are in the repurposing of three pins for the graphics adapter secondary RGB signals. The CGA Intensity pin (pin 6) has been adjusted to Secondary Green (Intensity); the second ground of CGA (pin 2) has been adjusted to Secondary Red (Intensity), and pin 7 (Reserved on the CGA) is utilized for Secondary Blue (Intensity). If the graphics adapter is operated in the modes which contain the same scan rates as CGA, a connected CGA monitor should run properly. Although if the monitor connects pin 2 to ground, the shorting of the graphic adapter's Secondary Red (Intensity) output to ground could possibly damage the EGA adapter. It is highly recommended you run a free registry scan for and Intel Corporation Intel740 Graphics Adapter errors before installing any driver updates.
