Eagle TX Series AMOS Based Terminal Server Technical Manual, Rev. 01
Chapter 4 - System
Administration
AMOS provides a repertoire of program tools to support system administration functions. This chapter
covers many of these procedures, including:
•
Eagle TX Series CMOS setup information
•
Modifying the system initialization file to add jobs and terminals and change memory allocations
•
Flashcard utility software and software recovery procedures
EAGLE TX SERIES CMOS SETUP INFORMATION
When booting, the Eagle TX Series terminal server 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 options.
The CMOS RAM is on the AM-703 board in the Eagle 100TX, and is on the AM-138 CPU board in the
Eagle 450TX.
You can change the configuration even if you can’t boot the terminal server 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 of the terminal server. The first time you access these CMOS configuration
settings, 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 configuration settings.
Depress the RESET button on the terminal server front panel, and observe the output on the screen of the
terminal attached to port 0. You should see the following:

Press [ESC] to enter setup
You have 5 seconds after the second line to press the ESC key, otherwise the system will then start
downloading the flashcard contents to RAM disk.
The port 0 terminal’s baud rate must match the current configuration setting (default is 19.2K
baud) or the terminal server will not recognize the ESC character.
The screen should appear as follows:
