Processing details
The version is displayed as Firmware Version= V3.00. To obtain detailed version information,
execute PKUPDT2.EXE.
Note:
This definition utility operates on MS-DOS. It does not operate in a DOS box (in Windows). Be sure to
start MS-DOS before Executing.
Because this MSR utility uses a keyboard interface in communication with the firmware, operation of an
external keyboard and MSR read operations are strictly prohibited during execution. If such operation is
performed, errors may occur in data communication and proper operation may become impossible.
Reset or power OFF are strictly prohibited during operation of this MSR utility. Correct operation will
become impossible as it is not possible to conclude processing.
If executed with "CMDOFF" parameters, commands will not be received at all until Reset or Power OFF.
