[Test program]

Test programs on the MPC1000 can be run either using a Test OS or a JIG PC Flash Rom.

[Running the test Program using a Test OS

]

A test program can be installed on the MPC1000 by updating it with a Test OS. The Test OS must be copied to a CF card

from which it will be written to the Flash ROM of the MPC1000. The installation procedure is the same as for a normal OS

update. For a description of the test mode functions, refer to the “MPC1000 Test Program list”.

Note: Once the Test OS is installed, the unit will always start up using the Test OS, until the regular OS is re-installed.

[Running the test Program using a JIG PC Flash ROM MPC1K (AJ - 771312J)]

The PC Flash ROM is used during repair for the testing jig and boot block recovery.

To access the test program on the PC Flash ROM MPC1K follow this procedure:

1. Turn off the MPC1000 and open the unit.

2. Insert the PC Flash MPC1K ROM into J110 on the CPU board.

3. Turn on the MPC1000 to start up the Test OS from the PC Flash ROM.
