Abstract: A method of reducing the time needed for installing a combination of software programs onto a hard disk drive by creating modules for each software program and associating a file with each software program that records all changes made to files and directories by the installation process of that software program. When downloading combinations of these modules onto a hard disk drive, a software installation program is run which implements the changes to files and directories necessitated by each of the modules thereby resulting in a disk operating system that is properly configured for the operation of the combination of software programs.

Abstract: A method for reducing the time needed for setting up a computer system in a user selected language version of a disk operating system by pre-installing a plurality of modules for different language versions of disk operating systems. Upon initial power on by an end user, a minimal disk operating system runs a software setup program which installs the end user selected language version of the disk operating system and merges certain factory loaded files into the user selected language operating system. A software installation program is then run which implements the changes necessitated by each of the modules for proper operation thereby resulting in a disk operating system that is properly configured for the operation of the combination of software programs. The computer system is then re-booted to implement the changes to the configuration of the disk operating system.
