MEMORY SLOT POPULATION

Single or dual rank memory modules must be placed in the SLIs DIMM sockets using prescribed population rules to ensure proper memory interface operation and performance. Installing two DIMMs which are identical in type, size and rank in DIMM sockets 1B and 1A results in dual-channel operation. If an additional pair of DIMMs is installed in sockets 2B and 2A, the DIMMs must be identical in type, size and rank to each other, but may be different in size from the pair installed in sockets 1B and 1A. If the modules in channel B and channel A (e.g., 1B and 1A) differ in size, the BIOS will use the size of the smallest DIMM. For more details refer to the SLI Memory Interface technical details.

The following table explains the DDR2-400 DIMM population rules:

NOTE: SINGLE and DUAL refer to DIMM rank.

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 SLI boards 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 an SLI system host board, the IOB31 provides an extra x4 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 an SLI SHB.

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

Microsoft® Windows® Vista
Microsoft® Windows® 2000
Microsoft® Windows® XP
Microsoft® Windows® 2003 Server
Mic, rosoft® Windows® NT
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:

SCO 5.07
