ABSTRACT:

BACKGROUND
A personal computer system board needs to recognize whether it is installed in the correct personal computer chassis. Such recognition is necessary because the system board functions differently depending on the type of chassis. Previously, encoder riser cards or jumper settings were used to determine whether the system board was installed in the correct computer chassis. However, these methods have either become obsolete or are not efficient. Accordingly, what is needed is an apparatus and a methodology for automatically determining whether a system board has been installed in the correct type of computer chassis.
SUMMARY
The present disclosure describes a method to allow a computer system board to automatically identify the personal computer chassis in which the system board is installed. The method includes the steps of a) attaching at least one spring action grounding clip to the chassis, b) incorporating at least one conducting pad into the artwork of the printed wire assembly on the system board, c) connecting at least one conducting pad to a logic circuit on the system board, d) installing the system board in the chassis, and e) ensuring that at least one spring action grounding clip contacts at least one conducting pad.
