OTHER ENVIRONMENTAL REQUIREMENTS

MEMORY SLOT POPULATION

Memory modules can be installed in one or both DIMM sockets. If only one DIMM module is used, it may be populated in either DIMM socket (BK1 or BK2). To operate at maximum bandwidth, two DIMMs of the same size must be installed, but the DIMMs may differ in technology (component density) and/or device width.

The SHB provides two types of memory operation, depending on how the DIMMs are populated. Asymmetric mode occurs when only one DIMM is installed or when two DIMMs are installed but differ in size. In the latter case, memory addressing begins with channel A, and when the top of channel A is reached, addressing starts at the bottom of channel B. The total system memory is the total installed in both channels, but accesses occur only at a width of 64 bits.

Interleave mode enables the highest memory interface speed and bandwidth throughput capacity. This is achieved by using two DIMM modules of the same memory size, although the DIMMs may vary in technology and/or device width. If the DIMMs are of different speeds, the slower memory module determines the memory interface speed.

NOTE: To maximize system performance and reliability, Trenton recommends using DIMMs that support the Serial Presence Detect (SPD) data structure. All memory modules must have gold contacts.

IOBxx EXPANSION BOARDS (OPTIONAL)

These optional boards provide legacy I/O connections via the Super I/O controller (LPC47B272).The I/O controller on an IOB30/31 connects to the SHB¡¯s LPC Bus via the board¡¯s controlled impedance connector. The following I/O interfaces are supported by the TML via either the IOB30 or an IOB31 variation:

• 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/IOB31 supports up to two floppy disk drives in combinations of 360K to 2.88MB.
• KEYBOARD 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/2™, 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 IOB30 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 a T4L system host board, the IOB31 provides an extra x1 PCI Express link to the backplane.

Operating systems exhibit certain boot-up behavior with regard to the handling of keyboard controller functions that may necessitate the addition of the IOB30 or IOB31 with leqacy I/O support to a T4L SHB.

The operating systems that Trenton has tested that do not require the IOB30, or IOB31 are:

Microsoft® Windows® Vista 64-bit & 32-bit
Microsoft® Windows® 2000
Microsoft® Windows® XP 64-bit & 32-bit
Microsoft® Windows® 2003 Server 64-bit & 32-bit
RedHat Linux
Fedora Core
SUSE Linux Server
Linux Enterprise Server
QNX Netrino
Sun® Solaris™

The operating system that Trenton has tested that require the IOB30 or IOB31 in order to provide required PS/2 keyboard functions are:
