2.5.6 PATA Storage
The Crown Beach Board provides only one desktop, 40-pin, PATA66/100 connector
that supports master and slave devices.
2.5.7 USB Connectors
The Intel® SCH provides eight USB 2.0 ports.
• Four ports are routed to the back panel’s two stacked USB connectors. USB ports
[1:0] and [4:3] are routed to the back of the chassis.
• Port 2 is the client-mode connector and is routed to the back of the chassis with a
Mini-B connector.
• Ports [7:5] are routed to the front panel headers (USB FPIO, Duck Bay, and
Sideband Header) and to the Sideband headers (Duck Bay, Upham USB).
• For wireless solutions port 0 is also used with stuffing options for the PCI Express*
Mini Card. OC [7:0] # is available for over-current detection.
• Port 5 is disabled by default due to enabling of PCI Express* Mini Card A Slot.
Note: USB port 0 functionality is impacted if rework is performed to enable the PCI Express*
Mini Card B Slot.
