1-12 Chapter 1: Product Overview<br />
Hardware Monitor<br />
The hardware monitor generates an interrupt to the system whenever<br />
any of the internal voltages used by the system processor goes above or<br />
below the acceptable operating range. An interrupt is also generated<br />
when the temperature of the Processor exceeds safe levels. Software<br />
can use this indication to slow or stop the system and/or force a reset.<br />
PCI Expansion Header<br />
A single expansion header is provided to support optional features,<br />
such as the PCMCIA for Wireless LAN Board. This board supports two<br />
Type 2 or one Type 3 PCMCIA-type cards.<br />
IDE Header<br />
Two IDE headers are provided to support the 2.5" hard disk drive and<br />
the optional integrated CD-ROM.<br />
Audio<br />
The base unit has Sound Blaster-compatible audio. Wave table<br />
synthesis is not supported. FM synthesis and MIDI are supported in<br />
the hardware, but require software driver support to function.<br />
A Line Out is provided on a 3.5mm stereo jack that permits connection<br />
of external amplified speakers.<br />
The amplifier connected to Line Out must be used in order to play<br />
Sound Blaster (audio subsystem) audio. However, an internal EUI<br />
speaker provides PC speaker functionality (beeps and tones) for all<br />
configurations.<br />
The volume control can be set during system configuration.
