Functions for DOS-less Embedded PC applications.

This archive contains several programs which are useful in developing
code for PC hardware that runs without an operating system.

MKBOOT is a utility that installs a custom boot loader, allowing you to
load and execute any file, by booting it directly from floppy disk.

MDCFS is the 'C' source code for a "Minimal Dos Compatible File System",
these functions allow you to read and write to DOS format disks without
DOS. Basic open/close/read/write/delete functions are provided.

WINDOW is a set of very small ASM and 'C' functions which implement
"character based" windows using direct memory writes. Supports multiple
open windows, save/restore overlaid text, borders, scrolling, line-wrap
and LOTS more.

COMM is a set of interrupt driven serial I/O functions, which use standard
PC serial ports.

JOYSTICK is a function which reads the digital and analog inputs of the
PC's game (joystick) port.

Source files are compatible with the ASM86 assembler, and MICRO-C/86
compiler from DDS 8086 Developers Kit.
