In a normal system power up the following takes place:
1. Power to the monitor and system unit is turned on. Both
power indicators are on.

ROM version, assorted copyright information, and the memory
size. Depending on the option(s) installed in the system

about the operating system, and gives the date prompt. Note
that the actual information displayed at this time depends on
the system software.
