Abstract

The hard disk drive of a computer system is loaded with a preloaded image including an operating system, a number of application programs, and a device driver installation routine, all of which are not dependent on the hardware configuration of the computer system. A hidden partition of the hard disk drive is also loaded with a number of device drivers, which are dependent upon the hardware configuration. During the first boot only of the preloaded image, the device drivers are installed by the device driver installation routine.

d) resetting code indicating that said initialization process is occurring for a first time to indicate that said initialization process has occurred before.

11. The method of claim 10, wherein

step a) is preceded by a first initialization routine,

step d) is followed by loading an operating system,

following said first installation routine, a process executing in said computing system reads said boot record,

before step d) occurs, said master boot record directs said process executing in said computing system to step c), and

step d) includes rewriting said master boot record to point to a step beginning a process of loading said operating system.

12. The method of claim 10, wherein step c) includes:

loading a device driver installation routine stored within a hard disk drive of said computing system in a bootable structure of computer readable code; and

executing said device driver installation routine to write device driver routines stored within a non-bootable structure of computer readable code within said hard disk drive to a first database within said bootable structure and to write locations of said device driver routines in said first database to a second database within said second database.

13. The method of claim 10, wherein

said bootable structure additionally stores said operating system, and

information stored within said bootable structure is not dependent on a specific hardware configuration.

14. A method for providing program instructions for use within a computing system, wherein said method comprises:

storing device drivers corresponding to devices within said computing system in a first structure of computer readable code within a hard disk drive of said computing system; and
