HARDWARE CONFIGURABLE OPTIONS
The following sections summarize the configuration options available to let you tailor your hardware to your needs. Most of these options require access to the main circuit boards inside the computer, and should be performed only by qualified technical personnel. Contact your VAR if you need assistance.
Printed Circuit Board Configurations

•
One 25-pin SPP/ECP/EPP parallel port
•
Integrated video graphics controller for system display console
•
PS/2 keyboard and mouse ports
•

AM-8000 CPU Board Configuration
Figure 2 shows the AM-8000 CPU board configured as shipped by Alpha Micro. The standard jumper positions are listed along side the figure. All jumpers should be left in their factory configured positions.
Figure 2: AM-8000 CPU Board Configuration
If you ever need to replace the AM-8000 CPU Board, you will need to enter the 12 digit CPU PIC number into your system software. The CPU PIC number is located on the CPU board as shown in
Figure 2. Write this CPU PIC number down before installing the CPU board. The first time you boot up your AM-8000 after replacement of the CPU board, follow the procedure below to identify the new CPU board to the system software:
•
Once the AM-8000 starts to boot, depress the CTRL C key combination for the boot job
(VTM1) and make sure the job is at command level.

key combination on the keyboard to display the AM-8000 System
Diagnostic window.
•
Mouse click on Configure. The AM-8000 configuration screen will be displayed.
•
Move the mouse cursor over the “Magic Code” input box, click inside the box, and type in the 12-digit number of the CPU PIC you wrote down previously from the label on the new CPU board.
•
Depress
RETURN
on the keyboard. After a short period of time, if the CPU PIC installation was successful, you should see the message “Verification passed”. If you typed the wrong 12-digit number, the following error message should appear:
?Magic code verification failed - please re-enter OK
If this happens and you did not make a mistake typing the 12-digit number, mouse click on Tools in the AM-8000 diagnostic window. Select Control Panel. In the
Address box, select the Down Select button. Browse to the C:\AM8000 folder.
Browse in the AM8000 folder and find “amcfg.cfg” file. Email this file to [email protected]
, identifying who you are, what your system serial number is, and the CPU PIC that you entered.
AM-113-50 MultiFunction Coprocessor
The AM-113-50 Multifunction Coprocessor board is a PCI compatible board that plugs into the first 32bit PCI slot on the AM-8000 CPU board. It contains the following functions:
•
SSD (Software Security Device) chip
•
Four high performance serial ports
•
One paddle card bus for externally connecting up to 15 serial I/O cards (8 ports per card)
•
Hardware timer
•
Optional uninterruptible power source (UPS) monitor port
•
Optional front panel display port
Up to two AM-113-50 Multi-Function boards may be installed in the AM-8000, providing support for up to 30 serial I/O cards via the AM-359 boards (8 ports per card).

AM-113-50 MultiFunction Coprocessor Board Configuration
The AM-113-50 Multifunction Coprocessor board has been factory tested and shipped with its configuration jumpers set in their standard default positions, as specified in Figure 3. The only userconfigurable jumpers are the board addressing jumpers. All other jumpers should be left in their factory configured positions.

Replacing the Time and Date Battery
When replacing the battery on your CPU board, always be sure to power-down the system first!
DO NOT replace the battery with the power on! As always, when opening your computer chassis, take proper precautions against electrostatic discharge, which can seriously damage system components.
The board uses one three-volt lithium battery (part #CR2032) that will last for approximately two years.
To remove the existing battery, which is about the size of a quarter, you must slide it out from under the top spring contact. It may be necessary to lift the top spring contact slightly to remove the battery from the plastic well that holds it in place. Do not bend the spring arm, or you will lose the contact tension and the battery backup will be intermittent.
When installing the new battery, make sure the positive (+) side is facing up and the top spring arm contact is pressing down firmly to hold it in place.

After installing a new battery, the system BIOS setting will be reset to factory defaults. These are not optimized for the AM8000. In Appendix A, you will find the optimal settings. See the following section for restoring your BIOS settings to those optimized for the AM-8000.
Restoring Your BIOS Settings
Besides the time and date, the AM-8000’s battery also maintains the system setup parameters and boot device parameters These are stored in AM-8000’s on-board BIOS chip. Therefore, when you remove and replace the battery, your BIOS settings will be lost. After you install the new battery and turn system power on, you need to access the BIOS Configuration menu by pressing
F2
during POST and restore your settings. Refer to the AM-8000 Owner’s Manual for additional information.
If you do not use the BIOS configuration menu to restore your settings, the system will drop into standard factory defaults and boot the AM-8000 with parameters which are not optimized for the system.
Yet, when it does start to boot, the AlphaShell.Exe will boot the system with AM8000.MON and
AM8000.INI as the system parameters..
Once the system is up and running, log to OPR: and enter the current time and date. Reboot the system to initialize the system up time.
SSD Chip Removal
The SSD chip is located at U13 on your AM-113-50 Multifunction Coprocessor board, as shown in
Figure 3. The type of socket used for the SSD chip requires a special tool for chip removal. If you ever need to remove and replace this chip, be sure to use the correct tool, as shown in Figure 4.
WARNING!
The SSD chip on the
AM-8000
Multifunction I/O board requires a specialized tool for its removal. If you attempt to remove the SSD chip using a screwdriver or pocketknife, you could easily damage both the chip and the socket. This type of chip extraction tool is available at retail stores specializing in electronic components.
