Procedure #6: Alternate Boot
You perform this procedure when previous procedures indicate something may be wrong with the
software on your System Disk. This procedure sees if the computer can boot off some other device—
whether or not this succeeds tells your VAR quite a bit about what might be wrong with your computer.
First, make sure the device and unit number settings for the alternate device you are trying to boot from
are correct on the CMOS menu. Refer to Chapter 2 for details on the CMOS configuration menu.
Once you are sure of your alternate boot device settings, follow these steps to warm boot from a tape:
1. Load your warm boot tape into your streaming tape drive.
2. Push your computer's Reset button. In about 30 seconds you should see a message giving the
version number of the operating system. Then, the AMOS prompt symbol, a dot, displays.
If you do see the operating system message and a dot, you have successfully warm booted.
Because this is a warm boot you do not see the system initialization command file on the
operator terminal. Go to the next step.
If you do not see the operating system message and a dot, try performing the warm boot once
more. If you still do not see the message, call your VAR for help. Stop.
3. Enter the following command:
DIR SYS:AMOS*
RETURN
If your terminal displays a list of files including two with .INI and .MON extensions, you know
at least some of your System Disk is intact.
Although once you are familiar with the computer you can easily restore the System Disk
yourself, we recommend that as a new user you contact your VAR for help at this point. Stop.
USING LEVEL7
LEVEL7 is a diagnostic utility which lets you examine certain aspects of your system , even when it
appears to be locked and other AMOS programs won’t work. While it is not used often, it can be very
valuable in finding and fixing certain types of problems. If your system is configured to allow it (most
AM-6060s are), you can start LEVEL7 by pressing the Turbo button on the computer’s front panel (see
Figure 2-1).
The Turbo button is a toggle switch; when you press it, the AM-6060 enters a LEVEL7 state, and will
run only LEVEL7. Press the Turbo button again to enable your computer to boot and run normally.
Pressing the button the second time does not “kick you out” of LEVEL7; it just means that when you
leave LEVEL7 the computer will reboot normally. We strongly suggest you always press the Turbo
button again as soon as you start LEVEL7; otherwise, your computer will not boot or run normally when
you’re finished using LEVEL7.
How to enable the Turbo button to start LEVEL7 is described in the AM-6060 Service Manual. LEVEL7
itself is covered in the LEVEL7 Non-Maskable Interrupt Debugger, DSS-10550-00.
