Micro-Star MS-5169 Motherboard Floppy Drive Controller Question

Discussion in 'MSI' started by Allan Sadowski, Oct 5, 2004.

  1. I bought a Micro-Star MS-5169 Motherboard cheap
    on Ebay.

    My question is the motherboard floppy drive
    controller connection is missing pins 4, 5, and 6.

    The pins are not broken off but have been left off
    the connection.

    On the other motherboards that I have they have
    always had all the pins on the floppy drive
    controller connection.

    I have not installed the motherboard yet but
    would like to know is there a reason these
    pins are missing?
