Abstract

System, method and program for installing a first operating system, including a first hardware abstraction layer and other operating system functions, into a client computer. An image of the other operating system functions and a second hardware abstraction layer is loaded into the client computer. The second hardware abstraction layer is functionally interrelated with the second hardware abstraction layer in the image. There is automatic detection that the second hardware abstraction layer loaded into the client computer is incompatible with the client computer. In response, the second hardware abstraction layer with the first hardware abstraction layer is automatically replaced in the client computer. Subsequently, the first operating system including the first hardware abstraction layer and the other operating systems functions is booted up in the client computer. In one example, the operating system is Windows XP, the first hardware abstraction layer is adapted for an ACPI PIC type client computer, and the second hardware abstraction layer is adapted for an ACPI APIC type client computer.

Claims

1. A method for installing a first operating system, including a first hardware abstraction layer and other operating system functions, into a client computer;

said method comprising the steps of;

loading an image of said other operating system functions and a second hardware abstraction layer into said client computer, wherein said second hardware abstraction layer is functionally interrelated with said second hardware abstraction layer in said image;

automatically detecting that said second hardware abstraction layer loaded into said client computer is incompatible with said client computer, and in response, automatically replacing said second hardware abstraction layer with said first hardware abstraction layer in said client computer; and

subsequently, booting up said first operating system including said first hardware abstraction layer and said other operating systems functions in said client computer.

2. A method as set forth in claim 1 wherein said operating system is Windows XP.

3. A method as set forth in claim 1 wherein said first hardware abstraction layer is adapted for an ACPI PIC type client computer, and said second hardware abstraction layer is adapted for an ACPI APIC type client computer.

4. A method as set forth in claim 1 wherein in response to the step of automatically detecting that said second hardware abstraction layer is incompatible with said client computer, further comprising the step of automatically loading said first hardware abstraction layer into said storage of said client computer before the step of automatically replacing said second hardware abstraction layer with said first hardware abstraction layer in said client computer.

5. A method as set forth in claim 1 wherein the loading step comprises the step of restoring said image to a bootable form in said client computer.

9. A system as set forth in claim 1 further comprising means, responsive to the automatic detecting means detecting that said second hardware abstraction layer is incompatible with said client computer, for automatically loading said first hardware abstraction layer into said storage of said client computer.

6. A system for installing a first operating system, including a first hardware abstraction layer and other operating system functions, into a client computer;

said system comprising;

means for loading an image of said other operating system functions and a second hardware abstraction layer into said client computer, wherein said second hardware abstraction layer is functionally interrelated with said second hardware abstraction layer in said image;

means for automatically detecting that said second hardware abstraction layer loaded into said client computer is incompatible with said client computer, and in response, automatically replacing said second hardware abstraction layer with said first hardware abstraction layer in said client computer; and

means for subsequently, booting up said first operating system including said first hardware abstraction layer and said other operating systems functions in said client computer.

7. A system as set forth in claim 6 wherein said operating system is Windows XP.

8. A system as set forth in claim 6 wherein said first hardware abstraction layer is adapted for an ACPI PIC type client computer, and said second hardware abstraction layer is adapted for an ACPI APIC type client computer.

10. A system as set forth in claim 6 wherein the loading means comprises means for restoring said image to a bootable form in said client computer.

11. A computer program product for installing a first operating system, including a first hardware abstraction layer and other operating system functions, into a client computer;

said computer program product comprising;

a computer readable media;

first program instructions to load an image of said other operating system functions and a second hardware abstraction layer into said client computer, wherein said second hardware abstraction layer is functionally interrelated with said second hardware abstraction layer in said image;

second program instructions to automatically detect that said second hardware abstraction layer loaded into said client computer is incompatible with said client computer, and in response, automatically replace said second hardware abstraction layer with said first hardware abstraction layer in said client computer; and

third program instructions to subsequently boot up said first operating system including said first hardware abstraction layer and said other operating systems functions in said client computer; and

wherein

said first, second and third program instructions are stored on said media in functional form.

12. A computer program product as set forth in claim 11 wherein said operating system is Windows XP.

13. A computer program product as set forth in claim 11 wherein said first hardware abstraction layer is adapted for an ACPI PIC type client computer, and said second hardware abstraction layer is adapted for an ACPI APIC type client computer.

14. A computer program product as set forth in claim 11 further comprising fourth program instructions, responsive to said second program instructions detecting that said second hardware abstraction layer is incompatible with said client computer, to automatically load said first hardware abstraction layer into said storage of said client computer;

and wherein

said fourth program instructions are stored on said media in functional form.

15. A computer program product as set forth in claim 11 wherein said first program instructions restore said image to a bootable form in said client computer.
