Extra Notes: Jeff Prosise was a staple of PC Magazine, and this book captures the peak of the DOS era just as Windows 3.0 was beginning to take over. It is highly valued by retro-PC hobbyists who build "period-correct" 386 and 486 systems, as the techniques inside are essential for squeezing every kilobyte of conventional memory out of a DOS setup.
