This library is very incomplete and under active development.

Don't blame me if things explode from using this library, etc. (I hate legal talk...)

lib866d

lib866d is a library for writing real-mode DOS software. It provides many functions for writing low level system software for DOS and compatible operating systems, and is intended primarily for utility and driver development.

Features

• 386ASM.H: Macros to use 32-Bit register and other 386+ level opcodes in inline-assembly
• ARGS: Sophisticated Program Argument Parsing
• CPU_K86: Low-level helper tools for manipulating AMD K86 Family CPU features (K5/K6)
  • EPMR, multiplier, MTRR, Write Order/Allocate, L1/L2 Cache
• DEBUG.H: Assertions and debugging features
• PCI: PCI Device access
• PICDMA : Interrupt controller & DMA controller access
  • Enabling/Disabling interrupts
  • EOI
  • DMA masking and unmasking
  • DMA setup
• SND_SB16 : SoundBlaster 16 access
  • 16-Bit Stereo DMA playback with interrupt callback
  • DSP readout
• TIMER : RTC oscillator-based timer with interrupt callback
• SYS: Low-level system configuration and hardware detection functions
  • System memory detection
  • 32-Bit Port I/O
  • CPUID reading, CPU MSR R/W, CPU Control Register R/W
  • DMA Memory allocation
• UTIL: Generic utility functions (string manipulation, etc)
• VESABIOS: Functions for getting VESA BIOS data and mode information
• VGACON: Functions for interfacing with the VGA text console and colorful string printing

Data types

The TYPES.H header provides generic access to all the data types.

To make things neat and concise, the data types are named intuitively:

• u8, u16, u32: Unsigned integer types
• i8, i16, i32: Signed integer types
• bool: Implementation for a boolean data type; implemented as an enum with two entries.

Supported compilers

• Microsoft C / C++ Version 6 / 7
• Borland Turbo C 3.xx
• OpenWatcom 2

How to use

There are only a few basic steps necessary to integrate lib866d into your project:

• Add lib866d to your include path
• Use the library in your code
• Compile the C files (e.g. using a wildcard LIB866D\\*.C) and link the appropriate objects with your program
