THE WARM BOOT MONITOR
The warm boot monitor is used in case of an emergency, when the computer cannot find the system
software files it needs to boot from on the hard disk.
As you become more familiar with your computer, we strongly recommend you create several warm
boot tapes. In addition, if you ever change the drive configuration or AMOS version of your computer,
you will almost certainly want to make all new warm boot tapes.
Use the WRMGEN program to generate a warm boot monitor, and the appropriate backup command to
place the monitor onto a tape. See the
AMOS User's Guide
and the
System Commands Reference Manual
for details on these procedures.
TURNING THE COMPUTER OFF
You need to turn off the computer whenever:
•
A technician needs to open the computer chassis for any reason.
•
You move the computer or servicing is required.
•
You add or remove external SCSI devices.
To turn off the computer always follow these steps:
1. Make sure all users have exited all programs and are logged off the computer.
2. Remove any backup media (such as streaming tape) from the computer.
3. If desired, turn off all devices connected to the serial ports, such as printers and terminals. You
do not need to turn off devices which are connected via the network.
4. Press the AC power button on the front panel.
EXPANDING YOUR COMPUTER
Your Alpha Micro VAR can assist you with setting up, expanding, or servicing your computer.
Once your computer is configured with the basic components, you may want to install any additional
subsystems purchased with your basic computer. Or, you may want to change your basic configuration to
add more users, change memory allocations, etc.
Part of adding new hardware to the computer involves changing the system initialization command file
to define the new hardware. Changing the allocation of system resources also requires changing the
system initialization file. For information on modifying this file, refer to Chapter 5 and the
System
Operator's Guide to the System Initialization Command File
.
Modifying the system initialization command file without understanding its elements is very
dangerous—a serious mistake could damage the file and leave your computer unable to boot
from it. Instead of modifying the file directly, make a copy, then edit and test the copy. Replace
the original file only when you know the copy works correctly.
