History of the PC's (Personal Computer's) BIOS (Basic I/O System) Code

Introduction It would take a group of accomplished authors working full-time to produce a textbook on the complete history of the PC BIOS in a reasonable amount of time. It will take us much longer to even produce a brief summary of how PC BIOS code has changed over the years. Though we have provided many details on special topics (such as Checksum Bytes and even some assembly listings), we are limited in the research we can conduct and the access we have to different computer types. Nevertheless, we hope to provide some data on this subject you may not find anywhere else; we appreciate your feedback.
