Additional Features

5.1 Watchdog

The conga-XLX is equipped with a multi stage watchdog. This solution can be triggered
by software and external OEM hardware (input pin is pin 48 on the X2 connector called
WDTRG#). For more information about the Watchdog feature see the BIOS setup
description section 8.5.8 of this document and application note AN3_Watchdog.pdf on
the congatec AG website at www.congatec.com.

5.2 Onboard Microcontroller

The conga-XLX is equipped with an ATMEL Atmega88 microcontroller. This onboard
microcontroller plays an important role for most of the congatec BIOS features. It fully
isolates some of the embedded features such as system monitoring or the I²C bus from
the x86 core architecture, which results in higher embedded feature performance and
more reliability, even when the x86 processor is in a low power mode.

5.3 Embedded BIOS

The conga-XLX is equipped with congatec Embedded BIOS and has the following
features:
ACPI Power Management
•
ACPI Battery Support
•
Supports Customer Specific CMOS Defaults
•
Multistage Watchdog
•
User Data Storage
•
Manufacturing Data and Board Information
•
OEM Splash Screen
•
Flat Panel Auto Detection
•
BIOS Setup Data Backup
•
Fast Mode I²C Bus
•
Real Headless Operation
•
Note
The conga-XLX embedded BIOS is based on the Insyde Xpress ROM BIOS and
therefore does not support 'System Plug and Play' mechanism.
