A memory system includes a flash ROM for storing the instructions for the BIOS, as well as a flash recovery ROM and a utility for programming both flash ROMs. The memory system also provides for flash disaster recovery in order to enable reprogramming of the BIOS ROM during a condition when the data in the BIOS ROM is found to be corrupt. In particular, the flash recovery ROM is provided with a hardware protected block. Sufficient BIOS instructions (e.g., initialization functions) are provided in the protected area of the flash recovery ROM in order to enable the BIOS ROM to be reprogrammed by way of a flash recovery utility when the BIOS ROM becomes corrupt. |
