2. Watch the CBMOD's seven-segment display: this allows you to observe the individual steps of
the system boot (Table 5-4).
The CPU is tested after the system starts. All LED segments of the seven-segment display are
activated by hardware default. If a decimal point is visible following the CPU test, an error has
occurred.
For example, if an error is detected during the RAM test, a "2" with a decimal point appears
permanently in the display. If this occurs, the CBMOD board should be replaced.
