Īll these display adapters have text modes in which each character cell contains an 8-bit character code point (see details), giving 256 possible values for graphic characters. The IBM Enhanced Graphics Adapter (EGA) contained an 8×14 pixels-per-character version, and the VGA contained a 9×16 version. The original IBM PC contained this font as a 9×14 pixels-per-character font stored in the ROM of the IBM Monochrome Display Adapter (MDA) and an 8×8 pixels-per-character font of the Color Graphics Adapter ( CGA) cards. Many file formats developed at the time of the IBM PC are based on code page 437 as well. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set.

This character set remains the primary set in the core of any EGA and VGA-compatible graphics card. It is sometimes referred to as the 'OEM font' or 'high ASCII', or as ' extended ASCII' (one of many mutually incompatible ASCII extensions). The set includes all printable ASCII characters as well as some accented letters ( diacritics), Greek letters, icons, and line-drawing symbols. It is also known as CP437, OEM-US, OEM 437, PC-8, or DOS Latin US. Code page 437 ( CCSID 437) is the character set of the original IBM PC (personal computer).
