 * The EEPROM consists of one 2816 type EEPROM providing 2K bytes
 * of electically erasable storage.  To modify the EEPROM, each
 * 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.
