Abstract:
1. A method for operating a diskless client computer using a disk based operating system where the client computer system must accommodate at least certain real-time applications, the method comprising the stops of: booting the client computer by fetching operating system modules through a network connection from a remote host computer; storing key operating system modules in a ramdisk as part of the booting of the client computer; locking the key operating system modules in ramdisk to prevent swapping of said modules by the operating system as part of the booting of the client computer; loading library and binary directories into random access memory as read-only files with consistency checking disabled as part of the booting of the client computer; managing the loading of programs stored at the host computer requiring real-time operation so that the programs are loaded as separate modules spaced-apart in time where the client computer is released between the loading of the separate modules to process other tasks; setting a value that corresponds to a time interval that will cause a time out error due to delay in obtaining requested information from the host computer, the value being set to be at least equal to the longest time interval that the client computer is to remain operational without being able to access the host computer.
