IBM VGA

VGA was introduced along with IBM's new line of next generation personal computers, the PS/2 line, in 1987. It was backwards compatible with EGA and introduced additional display modes. These were 640x480 in 16 colors or monochrome (the latter being equal to IBM's MCGA standard) and 320x200 in 256 colors. The standard was later succeeded by various 3rd party SVGA extensions and later still by XGA.

The first official VGA driver for Windows 1.0 was made by IBM (IBMPS250.DRV) and included with their OEM release of version 1.04 from 1987, shortly after the introduction of the first PS/2 models. This driver uses the 640x480 mode in 16 colors. A generic VGA driver was later included with Windows 2.0.
