J. If Status Code 2d or 3d remains on the display panel, your computer has encountered an error,

perhaps due to faulty memory or addressing. Perform "Procedure #5: Self Test." If your computer

does not pass the self test, call your VAR with the information from the test. Stop.

K. If the status code is 80 through 8C, you are in the self test mode. Perform "Procedure #3:

Powerup/Reset." If the computer boots normally, your problem is fixed; if it doesn't, call your

VAR.

L. If the Status Code is a number not discussed above, your computer is probably a victim of random

noise on the power lines or a software error.

Perform "Procedure #5: Self Test." If the computer does not pass the self test, call your VAR with

the information from the test.

If the computer passes the self test, perform "Procedure #3: Powerup/Reset"; if the computer comes

up normally, your problem is probably fixed. If it does not come up normally, call your VAR.

Procedure #3: Powerup/Reset

A. If the computer is already turned on, skip to Step B. To turn on the computer, follow the

instructions in Chapter 2. Remember—DO NOT hold in the reset button while you turn on the

computer or you will enable the self test.

The computer should now boot. Skip down to C, below, for instructions on how to tell if the

computer is up.

B. To reset the computer:

1. Before you reset the computer, make sure everybody is at AMOS command level—which is

when they see the AMOS prompt, usually a dot. If you reset while people are working on the

computer, they will lose whatever they were in the middle of. If any files are being written or

transferred to the disks, wait until that process is finished—if you reset while data is being

written to the disk, you might damage the data.

If anyone has files open, and cannot exit the program because his or her terminal is

locked up, go ahead and reset the computer. Then, after you are up and running, run

DSKANA on the disk where the file resides to check for disk errors. See Chapter 5 for

instructions on using DSKANA.

2. Push the reset button.

C. Check to see if the computer is up. If you see the system initialization command file displayed on

the operator terminal, and the last command is MEMORY 0, the computer has booted.

To make sure, type the following command:

SYSTAT

RETURN

Your terminal should display system status information.

If MEMORY 0 was the last command in the system initialization command file and the SYSTAT

command works, the computer booted successfully, and you can return to the procedure you are

performing or to the next procedure on your checklist.
