IDE Controller
   The 586/586E has two IDE connectors: a primary controller (50 pin) and the secondary controller (40 pin). Each controller supports two drives and can operate in PIO modes 0 through 4 and DMA modes 0 through 2. These interfaces support transfer rates of up to 16.7 MB per second,

L2 Cache
   The SBC has a single socket for the level-2 (L2) cache. This socket can be populated with a 512 KB cache module. L2 cache is not required for proper operation on the SBC. If L2 cache is not installed, the SBC operates using the internal cache on the microprocessor.

   The SBC has four 72-pin SIMM sockets organized into two banks of memory. These sockets can accept gold-tabbed, 60-ns, EDO parity SIMMs. These SIMMs can be 4 MB, 8 MB, 16 MB, 32 MB, or 64 MB. Each bank of memory must contain a pair of SIMMs identical in size, speed, and technology. The SIMMs do not have to be the same from one bank to another; the SBC will optimize for the maximum performance of each bank.

Power-On LED
This 2-pin connector on the SBC provides input to the system power-on indicator. It turns on the LED whenever 5 volts is applied to the SBC. The connector is attached through a cable to the system power-on LED (green).

HDD Access LED
This connector will drive a hard-disk-drive-accessed LED. It will light the LED whenever there is activity to either of the IDE ports. The connector 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.

Speaker LED
This 2-pin connector on the SBC is used to drive a speaker or an LED. A standard PC-class speaker can be connected to this connector and it will give the normal system audio outputs. The speaker connector is attached through a cable to the system speaker LED.

External Power Connector/Jumper Block
This 16-pin connector can be used to provide additional power to the SBC. The pin assignments depend on the SBC. The 586 and 586E SBCs do not support selectable core voltages, and the external power connector for these SBCs is used for power only. Additional power is not required if the SBC is plugged into a backplane that supports the PICMG standard.

Attention! Don't install jumpers on the 586 / 586E External Power Connector. The SBC will be damaged.
Attention! A Pentium MMX or AMD K6-2 on a 586 / 586E will be damaged when the system is turned on.

Hex Display
   The SBC provides a two-digit hex display, viewable from the top of the SBC. This disply gives
codes indicating the progress of POST. When the SBC has completed POST successfully, the
display shows a 00, and the operating system starts loading. If an error is detected during POST,
the error code is indicated in the hex display, as follows:
1. The start code of EE
2. The first two digits of the error code
3. The second two digits of the error code
4. The end code of EE

For example, if a 162 configuration error occurred at power-on, you would see EE 01 62 EE in the
hex display. This will repeat until you press a key.
Note: The 162 error will not display when the SBC is set to auto-configure mode. In auto-configure mode, the SBC automatically reconfigures itself and reboots.

Clear Password
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.

Clear CMOS
  The two pads are at the other upper edge of the CPU socket.
