ABSTRACT:

TECHNICAL FIELD
This disclosure relates to the field of computer systems, and, more particularly, to apparatus and methodologies for determining whether a personal computer system board has been installed in the correct personal computer chassis.
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, encoded 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 an apparatus and a method to allow a computer system board to automatically identify the personal computer chassis in which the system board is installed. The apparatus includes a) at least one conducting pad on the system board, b) at least one spring action grounding clip on the chassis, and in contact with the at least one conducting pad, and c) a logic circuit connected to the at least one conducting pad. 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.
