To build the operating system, a batch file (BUILD.BAT) is included to make life easier. This file is in the dos-c directory of the distribution. In addition, there is a corresponding batch file (CLEAN.BAT) to clean up the source directories. If you feel hardy, read on to understand the directory structure. A more complete description of the build environment is contained ina companion book, "The FreeDOS Kernel" (ISBN: 0-87930-436-7) published by R&D Books, an imprint of Miller Freeman of Lawrence, Kansas (USA) and distributed in the USA and Canada by Publishers Group West. See the file README.TXT for more details.
