IOB30MC / IOB31 I/O Expansion Board

IOB31 I/O Expansion Board

The Trenton Technology optional board provides legacy I/O connections via the Super I/O controller (LPC47B272). The IOB30’s I/O controller connects to the TQ9’s LPC Bus via the board’s controlled impedance connector. The following I/O interfaces are supported by the TQ9 via either the IOB30MC or IOB31:

Serial Interface

The Super I/O controller supports two full-function serial ports with independently programmable baud rates. The controller has two high-speed, NS16C550 compatible UARTs with Send/Receive 16-byte FIFOs. The IRQ for each serial port has BIOS selectable addressing.

Floppy Drive Interface

The IOB30 supports up to two floppy disk drives in combinations of 360K to 2.88MB.

KB and PS/2 Mouse Interfaces

The mini DIN connector located on the I/O bracket provides an external interface for a PS/2 mouse and keyboard. A "Y" adapter plugged into the mini DIN connector allows the PS/2 mouse and keyboard to share the same port. Internal PS/2 mouse and keyboard headers are also available. A self-resetting fuse protects the +5V line of the keyboard and the mouse.

Parallel Interface

The parallel port interface is compatible with IBM PC/XT®, PC/AT®, PS/2TM, Enhanced Parallel Port (EPP1.7, EPP1.9) and Extended Capabilities Port (ECP) modes of operation. Both the EPP and ECP modes are IEEE 1284 compliant. The parallel port has BIOS selectable addressing.

The IOB31 supports all of the same I/O functions as the IOB30MC using cable header connectors. There is no I/O plate on the IOB31. The IOB31 also provides a x4 PCI Express edge connector designed to fit into a PCI Express expansion slot on a PICMG 1.3 backplane. When used on the TQ9 system host board, the IOB31 provides an extra x1 PCI Express link to the backplane.

Operating systems exhibit certain boot-up behaviors in regards to the handling of keyboard controller functions that may necessitate the addition of the IOB30 or IOB31 to the TQ9.

The operating systems that Trenton has tested that do not require the IOB30MC or IOB31 are:

• Microsoft® Windows® Vista Business & Ultimate
• Microsoft® Windows® XP Professional
• Microsoft® Windows® 2000 Professional
• Microsoft® Windows® 2003 Enterprise Server
• RedHat Enterprise Linux 5.0
• Fedora 7.0
• SUSE Enterprise Linux 10.0

The operating systems that Trenton has tested that require the IOB30MC or IOB31 in order to provide required PS/2 keyboard functions is:

• Sun® Solaris™ 10.0
• Previous Linux versions
