{{anchor|Fontpage|Display|Printer|Default}}In computing, a '''hardware code page''' ('''HWCP''') refers to a [[code page]] supported natively by a hardware device such as a [[display adapter]] or [[printer (computing)|printer]]. The [[glyph]]s to present the characters are stored in the [[alphanumeric character generator]]'s resident read-only memory (like [[Read-only memory|ROM]] or flash) and are thus not user-changeable.<ref name="Paul_2001_CPSwitchFD"/><ref name="XyWrite_2009"/><ref name="Phoenix_1991_BIOS"/> They are available for use by the system without having to load any [[computer font|font]] definitions into the device first. Startup messages issued by a [[Personal computer|PC]]'s [[System BIOS]] or displayed by an [[operating system]] before initializing its own code page switching logic and font management and before switching to [[graphics mode]] are displayed in a computer's '''default hardware code page'''.
