[Podcast] An Inside Look at MS DOS

https://www.cs.drexel.edu/~johnsojr/2... An Inside Look at MS-DOS In this article, Tim Paterson details the fundamental architecture and design goals of MS-DOS, an operating system originally created to provide a hardware-independent interface for 8086 microprocessors. The system was built with a primary focus on CP/M-80 compatibility and operational speed, utilizing a specialized File Allocation Table (FAT) to manage disk space efficiently. The author explains the internal organization of the OS, which consists of a hardware-independent core, a device-specific I/O system, and a modular command processor. By keeping the FAT in main memory, MS-DOS optimizes file access and reduces the frequency of slow disk transfers. The text also explores how the system handles logical record requests by translating them into physical sector operations through a dedicated buffer. Finally, Paterson reviews the evolution of the software in version 2.0, noting improvements like subdirectories while critiquing changes to memory management. #classic #msdos #computer
