The setup of the configuration jumpers on the
SBC is described below.
* indicates the default value of each jumper.
|
NOTE: For two-position jumpers (3-post), "RIGHT" is toward the bracket
end of the board; "LEFT" is toward the memory sockets.
|
|
If the processor core gets to a critical temperature,
it slows itself down to half its normal speed. This jumper sets the
way in which the LED displays in response to this self-limiting
mode.
Install for real-time activity. The LED lights only when
the processor is operating in slow-power mode.*
Remove for latched activity. The LED lights and stays on once the
processor has gone into slow-power mode.
NOTE: Critical temperature is determined by the processor and
cannot be altered by the user.
|
|
|
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 on the RIGHT to clear.
Install on the LEFT to 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. Wait for at least two seconds and turn the power
off. Then remove the jumper and turn the power on. When AMIBIOS
displays the "CMOS Settings Wrong" message, press F1 to go into
the BIOS Setup Utility, where you may reenter your desired BIOS
settings, load optimal defaults or load failsafe defaults.
NOTE: If the CMOS settings are cleared, the processor may reset
to the safe mode, resulting in a reduction in execution speed which
affects overall system performance. After clearing CMOS, you should
always check the operating speed and reset it if necessary. To reset
the SBC to the correct operating speed, use the CPU Ratio CMOS Setting
option on the CPU Configuration screen. See the Advanced Setup chapter
of this manual for further details.

The
Double Data Rate (DDR) memory interface consists of two channels,
each terminating at a pair of DIMM sockets, providing a total of
four memory sockets. The SBC supports auto detection of up to 8GB
of memory. The System BIOS automatically detects memory type, size
and speed.
The SBC uses industry standard 72-bit wide gold
finger PC1600 or PC2100 memory modules in four 184-pin sockets.
The four memory
sockets on the SBC must be installed in pairs, beginning with the
sockets in Bank 1 (i.e., BK1A and BK1B), and must contain ECC registered
PC1600 or PC2100 DIMMs. All DIMMs must be the same speed (PC1600
or PC2100). The modules within a pair must be the same size; however,
if two pairs are used, each pair can contain a different size module.
DIMM sizes can range from 128MB to 2GB each. All memory modules
must have gold contacts.
The SBC supports DIMMs which are PC1600/PC2100
compliant and have the following features:
- 184-pin with gold-plated contacts
- ECC (72-bit) memory
- Registered configuration
The following DIMM sizes are supported:
