STEP 4 - CREATE A NEW SYSTEM MONITOR
Because of the Eagle 250’s CMOS configuration, you can give the system monitor file any name you
want. So, you can create a monitor to use after the AM-138-10 board is installed without affecting the
way your system performs now. Use MONGEN to create a monitor called AM138.MON, containing the
SCZ138 disk driver. For example:
LOG SYS:
ENTER
MONGEN
ENTER
Input monitor name: AMOS.MON
ENTER
New disk driver: SCZ138.DVR
ENTER
New language definition table name: ENGLSH
ENTER
New monitor name: AM138.MON
ENTER
SAVE AM138.MON
ENTER
This is only an example; be sure to choose the correct language definition table for your installation. All
other entries shown are correct for the Eagle 250.
The CMOS menu also allows you to boot from any SCSI disk. If the disk drive you will boot from
is not at SCSI ID 0, use FIXLOG to create a disk driver for the correct SCSI ID and use that driver
during MONGEN instead of the generic SCZ138.DVR. Otherwise, you will not be able to
MONTST using the new monitor.
STEP 5 - CREATE A NEW SYSTEM INITIALIZATION FILE
You need to make several changes to your system initialization (INI) file so the computer will boot
correctly after you’ve installed the Eagle 250 hardware. As with the monitor file, the CMOS
configuration lets you give this file any name you want, with an .INI extension. The steps below create
an initialization file called AM138.INI.
1. Copy your system initialization file to AM138.INI. Type:
LOG SYS:
ENTER
COPY AM138.INI=AMOS32.INI
ENTER
Edit the AM138.INI file.
2. Update the TRMDEF statements for the ports which will be attached to the AM-138-10 board.
It’s especially important to change port 0 (the boot terminal). You must change the interface
driver name to A31810, the driver used by the ports on the AM-138-10. For example:
TRMDEF TRMN,A31810=0:19200,AM62A,100,100,100
3. If you will be adding new serial ports (for example, a new AM-318-10 board) at the same time as
the AM-138-10, add statements defining the new ports. See the installation instructions for the
serial I/O board for details.
4. The high-performance features of the AM-138-10 board require more queue blocks. To
determine your new queue block requirement, use the following formula:
New Queue Block Requirement = Old Queue Blocks + (13 X Number of Jobs)
For example, if the QUEUE statement in your system initialization command file is currently set
to 200 and the JOBS statement is set to 50, the resulting formula would look like this:
