Front Panel Connectors
This motherboard has two possible configurations for the front panel connectors, a 1x19-pin header or a 2x9-pin header. The configuration is based on the type of case used.

1x19-Pin Header 2x9-Pin Header
The 1x19-pin header is intended for use in a case that utilizes individual connectors for each front panel function. The 2x9-pin header is intended for use in a case that utilizes a single, keyed front panel connector.
