Vga256

This is BGI driver for 256 colors VGA modes:

• 320x200x256
• 320x400x256

I wrote this driver in the first half of nineties for:

• Borland C++ 2.0
• Borland C++ 3.1
• Borland Pascal 7.0.

Tools required to build the driver:

• Turbo Assembler 2.51 (newer version may work)
• Borland C++ 2.0 or 3.1
• Borland MAKE 3.5

The makefile as provided will work for Borland C++ 2.0 & 3.1.

To build version 2 BGI driver simply issue 'make' in the directory with all files.

The version 2 BGI driver will work with Borland C++ 2.0 and 3.1 and real mode Borland/Turbo Pascal 7.0. It probably will works with Turbo C 2.0, Turbo C++ 1.0, Turbo Pascal 5.5 and Turbo Pascal 6.0.

To build version 3 BGI driver issue 'make -DBGI30' in the directory with all files.

The version 3 BGI driver will work with Borland/Turbo Pascal 7.0 in both real and 16-bit protected mode. It will not work with Borland C++ 2.0 & 3.1. It may work with Borland C++ 4.0 and up and may also work with 16-bit protected mode C++ applications generated with Borland C++ 4.0 and Borland Power Pack (this is just my wild guess, I never had a chance to try it). It will not work with 32-bit protected mode C++ applications.
