Abstract
A hibernation system of a computer employing option cards responds to a hibernation interrupt signal generated by a power management system in case of power failure or a period of non-use. In response, an operation controller backs up the present data and outputs a power supply cut-off signal. A basic input/output system calls a software interrupt for storing data when a hibernation suspension function is performed by the operation controller, and calls a software interrupt for restoring data when a hibernation resume function is performed. A plurality of option cards mounted on extension slots connected to the system bus patch the called software interrupt, and either perform an interrupt routine for storing option card register data and chipset data for initialization, or alternatively perform initialization according to stored chipset data and restore the register to a previous state, thereby performing a hibernation function responsive to every option card without overloading the basic input/output system even if the number of the mounted option cards is increased.
