The 8088 possessed a 20-bit address bus, allowing it to address a maximum of 1 MB of physical memory. This address space was strictly partitioned:
Govindarajulu covers the mechanics of how data is stored and displayed. This includes the internal operations of Floppy Disk Controllers (FDC), Hard Disk Interfaces (IDE/PATA and SCSI), and serial/parallel communication ports. It also charts the evolution of display adapters from text-only MDA to color-rich VGA standards. 5. Diagnostic Methodologies and Troubleshooting : By the mid-1980s, these clones were often
Because IBM used off-the-shelf components, any company could buy the same Intel CPU and support chips to build a matching motherboard. The only strictly proprietary element owned by IBM was the code embedded in the ROM chip.
