12. The apparatus of claim 1, wherein the second operating system comprises a virtual operating system that runs on top of the first operating system.

13. The apparatus of claim 1, wherein the apparatus comprises a general purpose personal computer.

14. The apparatus of claim 1, wherein the processor is configured to detect data corruption in the memory and limit access to the second operating system when data corruption is detected in the memory.

15. The apparatus of claim 1, wherein the processor is configured to load and activate the second operating system based on instructions supplied by the first medical device.

16. The apparatus of claim 1, wherein the processor is configured to receive the second operating system from the second medical device.

17. The apparatus of claim 1, wherein the second medical device is a patient therapy manager (PTM).

18. A computer comprising:

a memory comprising;

a first operating system for controlling general purpose functionality of the computer; and

a second operating system for controlling medical device programming functionality of the computer, enabling the computer to program a first medical device, wherein the first medical device comprises at least one implantable component; and

a processor configured to;

selectively boot and activate either the first operating system or the second operating system;

receive instructions from a second medical device different from the first medical device; and

boot and activate the second operating system in response to the instructions received from the second medical device.

19. The computer of claim 18, wherein the memory comprises a first region and a second region, wherein the first region is formatted for the first operating system and the second region is formatted for the second operating system.

28. The computer of claim 18, wherein the processor is configured to receive the second operating system from the second medical device.

29. The computer of claim 18, wherein the second medical device is a patient therapy manager (PTM).

20. A system comprising:

a first medical device that includes at least one implantable component; and

a personal computer comprising a processor that selectively boots and activates either a first operating system that provides general purpose functionality for the personal computer, or a second operating system, different from the first operating system, that provides medical device programming functionality for the personal computer to enable the personal computer to program the first medical device, wherein the processor is configured to receive instructions from a second medical device different from the first medical device, and wherein the processor is configured to boot and activate the second operating system in response to the instructions received from the second medical device.

21. The system of claim 20, wherein the processor boots and activates the second operating system from at least one of an external fixed or a peripheral non-fixed medium.

22. The system of claim 21, wherein the fixed medium is selected from the group consisting of a compact disc (CD) and a digital versatile disc (DVD).

23. The system of claim 21, wherein the non-fixed medium comprises a flash media device.
