/*
 * This structure defines the contents of the EEPROM for all Sun
 * Workstations with the SunMon monitor. (Sun Workstations with
 * the Open Boot monitor, e.g. SPARCstation-1, use a different
 * layout that is opaque to application programs. All access
 * to Open Boot-type EEPROMs is through monitor resources; see
 * eeprom(8) for more details.)
 *
 * The EEPROM is divided into a diagnostic section, a reserved section,
 * a ROM section, and a software section (defined in detail
 * elsewhere).
