For two-position jumpers (3-post), "RIGHT" is
toward the bracket end of the board; "LEFT" is toward the memory
sockets.
* = default value
INSTALL = Reset to null
REMOVE = Normal operation *
LEFT = Monochrome
RIGHT = Color *
The Flash ROM has two programmable sections: the
Boot Block for "flashing" in the BIOS and the Main Block for the executable
BIOS and PnP parameters. Normally only the Main Block is updated when
a new BIOS is flashed into the system.

INSTALL = Clear CMOS
REMOVE = Operate *
NOTE: The CMOS Clear jumper works on power-up. To clear the CMOS,
power down the system, install the jumper, then turn the power back
on. CMOS is cleared during the POST routines. Then power down the
system again and remove the jumper before the next power-up.
These two jumpers may be used to enable
or disable on-board active termination for the Ultra3 SCSI interface.

INSTALL = Enable 3.3V monitor
REMOVE = Disable monitor *
NOTE: JU15 enables the 3.3V monitor, which monitors the 3.3V power
plane of the backplane. This voltage is routed to the SBC via the
PICMG® connector. The monitor generates a RESET to the SBC if 3.3V
is below tolerance. If your system does not supply 3.3V to
the backplane, this jumper must be removed (disabled).
LEFT = Normal reset *
RIGHT = Enable watchdog

The Ethernet interface has two LEDs for status
indication and an RJ-45 network connector.
| LED/Connector |
Description |
| Link/Activity LED |
Green LED which indicates the link status. |
| Off = |
The Ethernet interface did not find a valid
link on the network connection. Transmit and receive are not
possible. |
On =
(solid) |
The Ethernet interface has a valid link
on the network connection and is ready for normal operation.
The Speed LED identifies connection speed. |
On =
(flashing) |
Indicates network transmit or receive activity. |
| Speed LED |
Amber LED which identifies connection speed. |
| Off = |
Indicates a 10Mb/s connection. |
| On = |
Indicates a 100Mb/s connection. |
| RJ-45 Network Connector |
The RJ-45 network connector requires a category
5 (CAT5) unshielded twisted-pair (UTP) 2-pair cable for a 100-Mb/s
network connection or a category 3 (CAT3) or higher UTP 2-pair
cable for a 10-Mb/s network connection. |
|
|
Pin 1 on the connectors is indicated by the square
pad on the PCB.

The
DRAM interface consists of two dual in-line memory module (DIMM)
sockets and supports auto detection of memory up to 512MB of Synchronous
DRAM (SDRAM) for the 440BX or up to 1GB of SDRAM for the 440GX.
Minimum memory size is 8MB. The System BIOS automatically detects
memory type, size and speed.
The SBC uses industry standard 64-bit or 72-bit
wide gold finger DIMM DRAM in two 168-pin DIMM sockets.
Memory can
be installed in one or both DIMM sockets. If only one DIMM module
is used, it must be populated in the top DIMM socket (Bank 1 - BK1).
If two modules are used, they must be the same DIMM type, but may
be different sizes (see table below). EDO DIMMs are not supported.
All DIMMs must have gold contacts.
The SBC supports DIMM memory modules which are
PC-100 compliant and have the following features:
- 168-pin DIMMs with gold-plated contacts
- 100MHz SDRAM
- Non-ECC (64-bit) or ECC (72-bit) memory
- 3.3 volt only
- Single or double-sided DIMMs in the sizes listed below
- Buffered or Registered configuration

All memory components and DIMMs used with the
SBC must be PC-100 compliant, which means that they comply with
Intel's PC SDRAM specifications. These include the PC SDRAM Specification
(memory component specific), the PC Unbuffered DIMM Specification,
the PC Registered DIMM Specification and the PC Serial Presence
Detect Specification.
