Abstract
The present invention is a method and apparatus to determine loading time of an operating system in a computer system. A basic input and output system (BIOS) retrieves a first time value from a real-time clock. The BIOS loads the OS into memory of the computer system. The OS has a device driver. The device driver retrieves a second time value from the real-time clock. A time difference is computed based on the first and second time value to obtain the loading time of the OS.
