multiPort, CN6 - Floppy Controller Mode
The MultiPort can be configured to be a floppy drive controller. This is selected in the BIOS Setup
under Integrated Peripherals. Only one floppy drive can be connected to the MultiPort, and it is con-
figured as the second drive.
Pin 1 is indicated by a square solder pad on the pin. This connector is located on the edge of the
cpuModule along the PC/104 bus. The following table shows the pin assignments to connect a flop-
py drive to the multiPort.
NOTE! To boot the CPU from the MultiPort Floppy, the following
steps must be taken:
• Drive A must be set to “1.44 MB” in the “Standard CMOS Settings”
section of BIOS Setup.
• Onboard MultiPort set to “Floppy” in the “Integrated Peripherals”
section of BIOS Setup.
• Swap Floppy Drive set to “Enabled” in the “Advanced BIOS Fea-
tures” section of BIOS Setup.
• First Boot Device set to “Floppy” in the “Advanced BIOS Features”
section of BIOS Setup.
• Floppy drive with adapter board is attached to CN6.
