* byte must be written separately. After writing each byte
* a 10 millisecond pause must be observed before the EEPROM can
* read or written again. The majority of the EEPROM is diagnostic
* and is defined in ../mon/eeprom.h. The software specific
* information (struct ee_soft) is defined here. This structure
* is 0x100 bytes big.
