2 Special Features

2.1 Primary LPC based Super I/O

Express modules do not contain any Super I/O because this is considered legacy. Therefore
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 LPC based BIOS

Express-BASE contains a socket for secondary LPC BIOS on board in addition to the soldered
BIOS on the Express module. Selection of active BIOS can be done by jumper settings

2.3 Integrated Debug Port with Single Step Execution

In addition to a two digit POST code display the board also provides four digits display for ad-
dress. By jumper selection the board can be switched into single step BIOS execution mode.
Steps are executed using a manually operated on board mini switch.

2.4 Audio Codec

The onboard stereo audio power amplifier contains two identical amplifiers capable of delivering
6 W per channel of continuous average power into a 4-W load at 10% THD+N or 5 W per channel
at 1% THD+N. The gain of each channel is fixed at 20 dB. The amplifier features a mute/standby
function for power-sensitive applications.

2.5 Information LEDs

General information is obtained through signalling LEDs for HDD, Power and Watchdog status.
Additionally the Express-BASE give information about module types being plug into the board.
