BAT Before Display Initialization
BAT before display initialization is a
sequence of tests that run before the
display is operational. Progress and
error codes are indicated on electron-
ic panel 1 where the five system sta-
tus LEDs show the BAT progress. The
status is shown by the electronics by
switching LEDs D through H on or off.
This generates patterns which are read
as BAT progress codes. These LED pat-
terns change as the BAT sequence
continues. BAT before display
initialization is shown in Figure 9-3.
The BAT stops when a test fails, which
permits the LED pattern to be read.
The five LEDs, D through H, display
system status.
