DOS is an acronym for Disk Operating System.  It provides file services to the

application programs, along with generic support for video and printing.  DOS

does not provide support for specific displays or printers, nor does it provide serĆ

vices for other peripherals.  These services are not common to all applications

written for the DOS environment.  Each application written for a DOS PC must

provide its own drivers for most of the peripherals that the application uses.

The actual DOS only consists of a small number of files, including an I/O interĆ

face and a command interpreter.  The DOS environment that is installed in a

typical desktop PC includes a large number of utility programs (for example,

CHKDSK.EXE) which are not required for the actual booting of a DOS PC, but

are supporting application files.  Note that these additional files are not loaded

into the PEN*KEY 6000 Series Computer in the default configuration, but are

available in the toolkit if needed by an application.
