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.
Therefore, a Super I/O is placed on the carrier board as an optional item. The Express-BASE
uses a Winbond W83627HG-AW that supports FDD, LPT, COM and PS/2 Keyboard and Mouse.
2.2 Secondary BIOS
The Express-BASE using firmware hub (FWH) for COM.0 Rev. 1.0 modules and Serial Peripheral
Interface (SPI) for COM.0 Rev. 2.0 modules. Selection of active BIOS can be made by jumper
setting
.
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-BASE has a Realtek ALC888 audio codec onboard. Audio I/O is provided by a six-
jack connector.
