—the SBC automatically adjusts the processor core-voltage during POST
– Pentium up to 200 MHz
– Pentium with MMX up to 233 MHz
– AMD K6-2 or K6-3 up to 500 MHz
Min 32MB, max 384MB. The SBC has two 168-pin DIMM sockets (bank 0 and bank 1). Each socket can accept gold-tabbed, non-parity, synchronous-DRAM DIMMs. The DIMMs can be 32 MB, 64 MB, 128 MB, or 256 MB.The DIMMs do not have to be the same size; the SBC will optimize for the maximum performance of each DIMM.
NOTE: Max RAM is (1) 128MB DIMM and (1) 256MB DIMM.
47L2707 32 MB DIMM, 10-ns, non-parity, gold tab
47L2708 64 MB DIMM, 10-ns, non-parity, gold tab
47L2709 128 MB DIMM, 10-ns, non-parity, gold tab

The SBC has a 512 KB level-2 (L2) cache, which cannot be upgraded.
Group A Connectors
J12, J7 Power-On LED
The power-LED connector turns on the system power-on indicator (the green LED) whenever 5 volts is applied to the SBC. It consists of two 2-pin connectors operating as a single connector. The connector pair supports the 2-pin LED connector in IBM systems and the 3-pin LED connector in industry-standard covers. The 2-pin power LED can be connected to J12 or J7. The 3-pin power LED can be connected across J12-1 and J7-1, or across J12-2 and J7-2.
J11 HD Access LED
This connector will drive a hard-drive-access LED. It will light the LED whenever there is activity to either of the IDE ports. The connector is a 2-pin header that connects through a cable to the HD-access LED (yellow).
J14 Reset Switch
This connector is used with a system reset switch. When the two pins are shorted together, the SBC performs a hardware reset. The connector is a 2-pin header attached through a cable to the backplane. When used in stand-alone mode, this connector can be attached to a system reset switch.
J19, J18 Speaker
The speaker connector consists of two 2-pin connectors. The connectors are used to drive a speaker or a speaker LED (in noisy environments). A standard 8-ohm speaker can be connected to give normal system audio outputs.
The two connectors act as a single header and support the 2-pin speaker connector in IBM systems or the industry-standard 4-pin connector. The 2-pin speaker cable can be connected to either J19 or J18. The 4-pin cable can be connected across both J18 and J19 (the two outer-most pins are used).
J15, J27 ATX Power Supply
The SBC provides two connectors to be used with the soft on/off control of an ATX power supply. The soft on/off control uses a momentary-make on/off switch connected to the SBC instead of the standard two-pole switch connected to the power supply. As a result, the SBC controls the on/off state of the power supply.
When using the soft on/off control, connect the on/off switch to the 2-pin connector (J15), and connect the 3-pin auxiliary power-supply cable to the 3-pin connector (J27). Note: Use only a momentary-make switch and a properly-wired power supply.
Group B Connectors
J9 Infrared Port
The infrared connector is a 5-pin, 2-millimeter, center-line connector. The infrared port is configured as a serial port and supports slow IR (SIR) and amplitude-shift keying IR (ASKIR) standards. To use this port, you need to construct the cabling with an external connector or external infrared device.
J8 Cover Intrusion Port
This connector is a standard 2-pin, 2-millimeter, center-line connector. The two pins are routed to the cover intrusion detector
The logic on the SBC works as follows:
The two connector pins on the SBC are routed to the detector circuitry. When the pins are shorted, an event is latched in the detector. The event is latched even if the computer is turned off or the power cord is unplugged. Bit 6 at I/O address 0158h contains the status of the latch. If bit 6 is 1, the latch has been tripped. The latch is reset by setting bit 6 at I/O address 0157h to 1. To use the logic to detect a cover being removed, the user must connect a switch that is closed when the cover is removed, and open when the cover is installed.
Removing a Power-on or System Administrator Password: If you need to remove either the power-on or system-administrator password:
1. Turn off the computer and remove the cover.
2. Use a screwdriver or other conductive device to short the two pads on the password clear pad for 10 seconds (refer to the following illustration). An alternative method is to remove the battery for 10 minutes.
3. Reinstall the cover.
4. Turn on the computer and run the Configuration/Setup Utility program.
5. If a password is required, you must enter a new one.
Switch Block 1
8 - 3 Reserved Leave these alone.
2 Disable Video Switch 2 on switch block 1 lets you disable the video function on the SBC. When this switch is down (on), the SBC disables all video drivers on the SBC. Default is video enabled (off).
Switch 1 on switch block 1 is used to disable the keyboard and mouse ports, preventing anyone from using the keyboard or mouse.
Default position is keyboard and mouse ports enabled (off).
Switch Block 2
8 Enable Auto Boot
Switch 8 on switch block 2 controls the SBC auto-boot feature at power-on. With auto boot enabled, BIOS detects configuration errors at power-on and automatically alters the CMOS settings to match the hardware so that the computer can complete the boot process without operator intervention. This is useful where an operator or keyboard and display are not available to clear the configuration error.
Use this carefully because it can mask hardware problems. Hardware errors could cause the computer to change configuration and possibly lead to inconsistencies in the operation of hardware and applications running on the computer.
Default position is auto boot disabled (off).
4 RS-422/485 or RS-232
Switch 4 on switch block 2 controls the electrical interface of serial port B. If the switch is up (off), the port is a standard RS-422/485 interface. If the switch is down (on), the port is a standard RS-232 interface. The default position is RS-232 (on).
Processor Speed Selection Switches
Switch block 2 is used to configure the SBC to the speed of the microprocessor. Switches 1 through 3 select the internal clock multiplier for the microprocessor. Switches 5 through 7 select the input frequency and external bus speed.
The following table shows the settings for the clock multiplier and the resulting internal processor clock for each CPU-input frequencies.
The following table shows the switch settings for the input clocks to the CPU, PCI bus, and host bus.
The table shows only the optimal settings for each CPU-input frequency.
Processor Voltage Selection
When the system is turned on, the SBC automatically selects the correct core voltage. The following shows the processors and the core voltages that are set.
