BOOT ROM DIAGNOSTICS
When the VP 300 is loaded or reloaded (loss of power, system error, or a command), the CPU and the
VCU execute a boot ROM diagnostic. The following describes how to access and interpret the boot ROM
errors.
Turn ON the terminal and set the speed to 300, 1200, or 9600 baud. At any of these speeds, the VP 300
prints or displays the diagnostic status. Turn ON the power to the cabinet. Press
repeatedly to
establish the baud rate. The complete message shown below is printed, except when an error is detected by
the boot ROM diagnostics. If errors are encountered, an error message is printed.
If a problem is found, the terminal displays a specific error number. Table 5-2 contains a list of possible
error numbers, a description of each error, and the most likely cause. When a failed assembly is returned
for repair, the specific error number provides additional information. When contacting your Technical
Support Center, indicate the boot ROM diagnostic error number.
The boot ROM diagnostic errors and their most likely causes are listed on the following pages.
