ABSTRACT:
A system, method and apparatus including a logic module, preferably embodied as an electronic card that operates in combination with a PC to correct errors caused by deficiencies existing in logic residing on the PC's motherboard, such as the PC's BIOS. The preferred logic card includes a transceiver module, a memory module (e.g. an EPROM or Masked ROM) containing storage elements and executable code stored as pages. The preferred logic card also includes a page register module in communication with the transceiver and the memory, and a paging mechanism that cooperates with the page register and the transceiver for allowing only a predetermined number of bytes (pages) of executable code to be accessible for operation in the PC's main-memory in order to correct errors caused by deficiencies existing in logic residing on the PC's motherboard.
