Sun PROM Monitor
To program the EEPROM or NVRAM using the Sun PROM Monitor, enter
q
followed by the hexadecimal address in the EEPROM or NVRAM to open and display
the contents. Change the contents by typing in the new value followed by
a carriage return. To exit, type a space and <CR>, or a "." and
<CR>.
