Jumpers
The processor board used in the SCALA L3 PC is largely free of selection jumpers. Most settings are controlled
from the BIOS, and stored in the CMOS memory. Only the following jumpers are significant
.
CMOS Clear
To clear the CMOS memory, first switch off the PC power, then locate the 3-pin header labelled
‘CLRTC’
on
the processor board which is beside the SYSFAN and Front Panel connectors. Remove the link shorting pins 1
and 2, and place it on pins 2 and 3 for about 5 - 10 seconds. Remove the link and replace it in its original
position. The CMOS has now been cleared and the BIOS will be reset to the default settings.
Having no link fitted is an invalid option.
