Abstract

Systems and methods for providing accelerated loading of operating system and application programs upon system boot or application launch are disclosed. In one aspect, a method for providing accelerated loading of an operating system comprises the steps of: maintaining a list of boot data used for booting a computer system; preloading the boot data upon initialization of the computer system; and servicing requests for boot data from the computer system using the preloaded boot data. In another aspect, a method for providing accelerated launching of an application program comprises the steps of: maintaining a list of application data associated with an application program; preloading the application data upon launching the application program; and servicing requests for application data from a computer system using the preloaded application data.

Claims

1. A system for creating an electrical boot-device-reset signal in advance of an electrical system-reset signal, the system comprising:

a first input configured to receive a power-supply-monitoring signal; and

a second input configured to receive the electrical system-reset signal;

wherein the system is configured to;

electrically differentiate the power-supply-monitoring signal to create the electrical boot-device-reset signal in advance of the electrical system-reset signal.

2. The system of claim 1, wherein a first time constant to differentiate the power-supply-monitoring signal is less than a second time constant to differentiate the electrical system-reset signal.

3. The system of claim 1, further comprising:

a logical gate configured to perform a logic OR operation between an electrical cold-boot-reset request signal and the power-supply-monitoring signal.

4. The system of claim 1, further comprising:

a logical gate configured to perform a logic OR operation between an electrical expansion bus signal and the electrical system-reset signal.

5. The system of claim 1, further comprising:

a logical gate configured to perform a logic OR operation between an electrical warm boot signal and the electrical system-reset signal.

6. The system of claim 1, wherein the system is further configured to generate an electrical cold boot identification signal flag.

7. The system of claim 1, wherein the system is further configured to generate an electrical warm boot identification signal flag.

8. The system of claim 1, wherein the system is further configured to form a connection to pass the power-supply-monitoring signal.

9. The system of claim 1, wherein the system is further configured to form a connection to pass an electrical expansion bus signal.

10. The system of claim 1, wherein the system is further configured to form a connection to pass an electrical warm boot signal bypass.

11. A method for creating an electrical boot-device-reset signal in advance of an electrical system-reset signal, the method comprising:

receiving a power-supply-monitoring signal;

receiving the electrical system-reset signal; and

electrically differentiating the power-supply-monitoring signal to create the electrical boot-device-reset signal in advance of the electrical system-reset signal.

12. The method of claim 11, wherein a first time constant to differentiate the power-supply-monitoring signal is less than a second time constant to differentiate the electrical system-reset signal.

13. The method of claim 11, further comprising:

performing a logic OR operation between an electrical cold-boot-reset request signal and the power-supply-monitoring signal.

14. The method of claim 11, further comprising:

performing a logic OR operation between an electrical expansion bus signal and the electrical system-reset signal.

15. The method of claim 11, further comprising:

performing a logic OR operation between an electrical warm boot signal and the electrical system-reset signal.

16. The method of claim 11, further comprising:

generating an electrical cold boot identification signal flag.

17. The method of claim 11, further comprising:

generating an electrical warm boot identification signal flag.

18. The method of claim 11, further comprising:

forming a connection to pass the power-supply-monitoring signal.

19. The method of claim 11, further comprising:

forming a connection to pass an electrical expansion bus signal.

20. The method of claim 11, further comprising:

forming a connection to pass an electrical warm boot signal.
