2.3 Normal Power Up

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.
2. The system executes its power-up tests, displays the BIOS
ROM version, assorted copyright information, and the memory
size. Depending on the option(s) installed in the system
additional information may be displayed.
If there is an error during any of the power-up tests the
system either generates a beep error code or displays an error
message.
3. The system generates a single beep, displays information
about the operating system, and gives the date prompt. Note
that the actual information displayed at this time depends on
the system software.
