Eagle 450 Installation and Technical Manual, Rev. 00
INITIAL SETUP AND TESTING
Before connecting the entire installation, it’s a good idea to test the main computer by itself and with
only the operator terminal attached. So, follow this procedure:
1.
Again, check the voltage switch on the back panel to make sure it’s set correctly.
2.
Attach the operator terminal to serial port 0 on the back panel. See the back panel picture in
Chapter 3 for the port location. By default, port 0 is set to an Alpha Micro terminal at 19.2K
baud.
3.
Plug the computer in.
4.
To start the self test, hold down the Reset button on the front panel while you press the Power
button to turn the computer on. If you aren’t familiar with the front panel of the Eagle 450, see
the
Eagle 450 Computer Owner’s Manual
.
See the
System Self Test User’s Guide
for information on running the self test and interpreting its
results. If the computer doesn’t come on, the self test doesn’t start, or the self test finds a
problem, see Chapter 5, “Troubleshooting.”
5.
After the self test has completed a full cycle of test, press Reset to end the test and boot the
computer.
Do not press Reset to end self test during the disk test portion. Doing so could damage the data on
the disk!
The computer should now boot using the default initialization file. Assuming it does so successfully, you
can continue by modifying the CMOS settings and/or the system initialization file.
MODIFYING THE CMOS SETTINGS
When booting, the Eagle 450 uses data stored in its CMOS parameters to find the primary and alternate
boot devices, the system monitor and initialization files to use, and other system options. The CMOS
RAM is on the AM-138 board; it is battery backed up and write-protected for data integrity.
You can change the CMOS configuration even if you can’t boot the computer under AMOS. This can be
very useful in case of certain system problems. To change the CMOS configuration, you must have a
terminal attached to port 0 on the AM-138 system board. The first time you access CMOS, this terminal
must be set to 19.2K baud; you can then change the terminal speed setting if you want.
It’s a good idea to write down the CMOS settings. If you need to replace the batteries, as
described in the
Eagle 450 Service Manual
, the settings are lost and must be re-entered.
