Description: Hailed by experts for its topical breadth and "hands-on" format, this thorough and visually appealing guide uses a step-by-step approach to teach the basics of PC architecture -- covering all x86 microprocessors from the 8088 to the Pentium Pro. Clarifying concepts with many real-world examples throughout, it offers intimate details of 80x86 assembly language programming, DOS memory map, BIOS, microprocessor architecture, interfacing techniques, system programming, hard disk characteristics and more. It uses the Debug utility to explore the internal working of the PC and microprocessor interfacing, shows readers early on how to combine assembly and C programming, and places all C programming in the last section of each chapter to accommodate those with no background in the subject

Discusses 8-bit, 16-bit and 32-bit interfacing of x86 microprocessor, and uses fragments of programs form IBM PC technical reference to show how PC system programming is being used in today's business world. Ensures an understanding of binary and hex numbering systems before delving into PC system programming, and analyzes hardware differences among 8086, 286, 386, 486, Pentium and Pentium Pro chips. Second edition features include: how to design your own PC interface card; discussions on PC interfacing (with real world devices such as LCD, stepper motor, ADC, DAC, and temperature sensors); programming I/O with C; serial and parallel ports programming in C; the latest DRAM technologies; and how to use new parallel ports.
