摘要：
An apparatus for accessing locked-down flash memory in a computer system that utilizes a general purpose input/output port coupled to the flash memory, and includes program instructions that generate a reset signal, output the reset signal to the general purpose input/output port, sense the reset signal, unlock the flash memory to allow write access to the flash memory, update the flash memory, and lock the flash memory to locked down mode. The present invention allows flash memory to be updated during normal operation of the computer system.
