booting: Porting Unix to the 386: Three Initial PC UtilitiesThe second article in the "PORTING UNIX TO THE 386" series discussed the utilities we had to build to test the port on an actual 80386 PC. Ironically, these utilities advanced progress fast enough that once the kernel was operational, the biggest obstacle became booting off of DOS. So the next step was to implement a bootstrap and standalone system so that we could rid ourself of DOS entirely. Porting Unix to the 386: The Standalone SystemThis article, last of the original three done altogether in 1990, on getting the critical pieces functioning independantly that we needed to do the port. Once these we obtained, the kernel was inevitable. A Brief Review of the RootA breakdown of the various uses of the root filesystems, and the considerations for each as we prove out the operation of the system step by step. Initialization: /sbin/init, /dev/console, and /bin/shWith the kernel running, we do a "high level bootstrap" to initialize the operating system, by executing certain programs located in the root filesystem. |
