In IBM PC compatible computers, the Basic Input / Output System ( BIOS ), also known as the system BIOS or ROM BIOS (), is a de facto standard defining a firmware interface.
In the IBM PC and AT, certain peripheral cards, such as hard-drive controllers and video display adapters, carried their own BIOS extension Option ROM, which provided additional functionality.
For example, an IBM PC might have either a monochrome or a color display adapter ( using different display memory addresses and hardware ), but a single, standard, BIOS system call may be invoked to display a character at a specified position on the screen in text mode.
So by reducing the number of tracks used and thus capacity, it was possible to further reduce cost-in contrast to Double Density drives used e. g. in IBM PC computers of the day which saved 180 kB on one side ( by using a 40 tracks format ).

The reverse was also true-VLB cards were by necessity quite long in order to reach the VLB connector, and were reminiscent of older full-length expansion cards from the earlier IBM XT era.
Ironically the VLB portion of a slot looked similar to a IBM MCA slot, as indeed it was the same physical 116 pin connector used by MCA cards rotated by 180 degrees.
The IBM MCA standard had not been as popular as IBM expected and there was an ample surplus of the connector, making it inexpensive and readily available.
IBM PC compatible CGA, HGC and some EGA graphics cards featured a connector for a light pen as well.
Video Graphics Array ( VGA ) refers specifically to the display hardware first introduced with the IBM PS / 2 line of computers in 1987, but through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640 × 480 resolution itself.
A Gender of connectors and fasteners | male D-subminiature | DE-9 connector used for a serial port on a IBM PC compatible computer.
While the RS-232 standard originally specified a 25-pin D-type connector, many designers of personal computers chose to implement only a subset of the full standard: they traded off compatibility with the standard against the use of less costly and more compact connectors ( in particular the DE-9 version used by the original IBM PC-AT ).
The desire to supply serial interface cards with two ports required that IBM reduce the size of the connector to fit onto a single card back panel.
Starting around the time of the introduction of the IBM PC-AT, serial ports were commonly built with a 9-pin connector to save cost and space.
For example, the 9 pin DE-9 connector was used by most IBM-compatible PCs since the IBM PC AT, and has been standardized as TIA-574.
IBM standardized the parallel cable with a DB25F connector on the PC side and the Centronics connector on the printer side.
When IBM implemented the parallel interface on the IBM PC, they used the DB25F connector at the PC-end of the interface, creating the now familiar parallel cable with a DB25M at one end and a 36 pin micro ribbon connector at the other.
