  • Fail-safe EEPROM based rewritable boot system
    Patent number: 5432927
    Abstract: A computer boot strap loading system employs dual, separable EEPROM units to facilitate safe reprogramming of bootstrap loader software. Both EEPROMs are adapted for storing bootstrap loading code. One of these two EEPROM areas is designated as the unit for which the code content will govern operation of the next reboot sequence. Circuitry is provided to monitor progress of a reboot to determine if a defect in the presently utilized reboot sequence is provided. Such a defect triggers a reboot from the other EEPROM as well as to provide a back-up copy of the bootstrap loading code most recently determined to be effective.
