Abstract

A method for providing event notification to an application is disclosed. The method may include sending a message to an operating system (OS) driver when a first event occurs. Code in a BIOS associated with the first event may be executed after the OS driver receives the message. A first notification generated by the BIOS may be provided to the OS driver.

Claims

1. A method for providing event notification to an application, the method comprising:

sending a message to an operating system (OS) driver when a first event occurs;

executing code in a BIOS after the OS driver receives the message, wherein the code is associated with the first event; and

providing a first notification generated by the BIOS to the OS driver.

2. The method of claim 1 further comprising:

registering a first application with the OS driver for notification of the first event; and

providing the first notification to the first application when the first event occurs.

3. The method of claim 2, wherein the first notification in supplied in a buffer accessible by the first application, and the buffer is in a size range between 4 KB and 2 MB.

4. The method of claim 1, wherein the message is a windows management instrumentation (WMI) message.

5. The method of claim 1, wherein the code in the BIOS is an ACPI (advance configuration and power interface) source language (ASL) code or an ACPI machine language (AML) code.

6. The method of claim 1, wherein the first notification includes additional data, and the additional data provides device presence and absence information, device insertion and removal information, status information, messages to be display to a user, or messages to be provided to an operating system.

7. The method of claim 1, wherein the OS driver comprises an advanced configuration and power interface (ACPI) and a windows management instrumentation-advanced configuration and power interface (WMI-ACPI) driver.

8. The method of claim 1, wherein a third party driver is not required to send a first notification.

9. The method of claim 3 further comprising:

providing a plurality of notifications associated with a plurality of events in the buffer.

10. The method of claim 9 further comprising:

Storing the plurality of notifications in an order in which the plurality of events are detected.

11. A computer-readable medium having computer-executable instructions for performing a method for providing event notification to an application, the method comprising:

sending a message to an operating system (OS) driver when a first event occurs;

executing code in a BIOS after the OS driver receives the message, wherein the code is associated with the first event; and

providing a first notification generated by the BIOS to the OS driver.

12. The computer-readable medium of claim 11, wherein the method further comprises:

registering a first application with the OS driver for notification of the first event;

providing the first notification to the first application when the first event occurs.

13. The computer-readable medium of claim 12, wherein the first notification is supplied in a buffer accessible by the first application, and the buffer is in a size range between 4 KB and 2 MB.

14. The computer-readable medium of claim 11, wherein the message is a windows management instrumentation (WMI) message.

15. The computer-readable medium of claim 11, wherein the code in the BIOS is an ACPI (advance configuration and power interface) source language (ASL) code or an ACPI machine language (AML) code.

16. The computer-readable medium of claim 11, wherein the first notification includes additional data, and the additional data provides device presence and absence information, device insertion and removal information, status information, messages to be display to a user, or messages to be provided to an OS.

17. The computer-readable medium of claim 11, wherein the OS driver is an advanced configuration and power interface (ACPI) and a windows management instrumentation-advanced configuration and power interface (WMI-ACPI) driver.

18. The computer-readable medium of claim 11, wherein a third party driver is not required to send the first notification.

19. The computer-readable medium of claim 13, wherein a plurality of notification associated with a plurality of events may be provided in the buffer.

20. The computer-readable medium of claim 19, wherein the plurality of notifications are stored in an order in which the plurality of events are detected.
