2 Special Features
2.1 Primary LPC based Super I/O
COM Express modules do not have a Super I/O chip onboard as this is considered legacy.
Consequently, a Super I/O is placed on the carrier board as an optional item. The Express-
BASE6 uses a Winbond W83627DHG-PT supporting COM and PS/2 Keyboard and Mouse. The
Winbond W83627DHG-PT supports a -40°C to 85°C temperature range and is pin compatible
with the W83627DHG-P.
2.2 Secondary BIOS
The Express-BASE6 supports the Serial Peripheral Interface (SPI) for COM.0 Rev. 2.0 modules.
Selection of active BIOS can be made by jumper settings. The location of the secondary BIOS is
U55 (see 3. Component Location).
2.3 Integrated Debug Port with Single Step Execution
In addition to a two-digit POST code display, the board also provides a four-digit address display.
By jumper selection the board can be switched into single step BIOS execution mode. Steps are
executed using a manually operated onboard mini switch.
2.4 Onboard Audio
The Express-BASE6 has a Realtek ALC886 audio codec onboard. Audio I/O is provided by a six-
jack connector.
2.5 Information LEDs
General information is obtained through signaling LEDs for HDD, Power and Watchdog status.
Additionally the Express-BASE6 gives information about module types being plug into the board.
See 8.2 Module Type Display on page 35 and 8.3 POST & Indicator LEDs on page 36.
2.6 Power, Reset, Lid and Sleep Switches
The Express-BASE6 is equipped four mini switches (SW1~4) for ATX Power, Reset, and COM.0
Rev.2.0 specified "Lid" and "Sleep" functions.
