DISK OPERATING SYSTEM LOADABLE FROM READ ONLY MEMORY USING INSTALLABLE FILE SYSTEM INTERFACE

摘要

A data processing system, such as a personal computer, contains bootable DOS programs that are stored in a ROM as an alternate file system in which the files are stored in packed format. When the system is powered on, the programs are rapidly booted up or loaded from ROM into RAM and executed to "instantly" (as it appears to the user) place the system in operation.
