Introduction
H Embedded USB Controller
- USB host controller (UHCI v1.0 compliant) with Root Hub
- Four USB ports with over-current protection
- Optional USB riser with 2 additional USB ports
H Optional IDE Accelerator
- High Point HPT370 IDE controller
- Supports extra two UltraDMA-100 IDE ports with RAID 0, 1 and 0+1
H Embedded System Monitoring Hardware Subsystem
- 5 external voltage inputs for CPU Vcore, +12v, +5v, 2.5v and 3.3v (internal
detecting)
- 2 temperature sensor with thermistor for CPU & System
- 2 Fan speed (CPU and System) monitoring and control with ON/OFF control
in suspend
H Board Dimensions
- Standard ATX form factor, 305mm x 210mm, 4 Layers
H Switching Power Supply Requirement
3.3V at 15Amps is necessary to guarantee full loading operation because
some AGP cards and memory modules have high current consumption.
