Failures and Hints

A. Error on boot time
1. Check if you have a bootable floppy or harddisk.
2. Check the CMOS parameter with the setup tools.
3. Reset the CMOS RAM with the reset jumper on the board. Close pin 1-2 for 5 seconds until the
power is off. Open the jumper W8 again and the system will start with BIOS-defaults.
4. Re-enter the correct values with setup.
B. If no display is available on the screen
1. Check the power circuitry.
2. Check the polarities of the cables.
3. Measure the voltage of the power supply underload and offload.
4. Measure the current between the supply and the MICROSPACE PC.
5. Connect a floppy: does the bezel led light blink?
6. Does the harddisk spindle motor start?
7. Reset the CMOS-RAM: see A.3.
C. If the error appears again
