A computer system and method provides a user the ability to restore operation to a previous state from a non-volatile semiconductor memory. The computer system includes flash EEPROM (electrically erasable programmable read only memory) or another non-volatile semiconductor memory for storing hardware configuration and other state information prior to a system power-down. The configuration information is used at power up to reconfigure devices coupled to the processor, such as a hard disk drive controller, video controller, sound card, and so on. Remaining memory in the computer system can be restored either from a hard disk drive (or other mass storage device), or from flash memory. The flash memory may be combined with fast semiconductor memory, such as dynamic random access memory (DRAM) in a module, such that the necessary amount of non-volatile memory may be added whenever fast semiconductor memory is added.
