NOTE: If an error condition is detected by the IRT test, the printer port LED displays an error
code after the IRT test finishes. For example, when the printer port LED displays 16h and
halts, the IRT test has already completed the KBC test. In this instance, the IRT indicates an
error with the system memory test. Error codes marked with an asterisk (*) indicate that the
IRT test aborts after the printer port LED outputs the error code.
