The USB interfaces support USB 2.0.2.15 BIOSThe WAFER-LX uses a licensed copy of AWARD BIOS. The features of the flash BIOSused are listed below: SMIBIOS (DMI) compliant Console redirection function support PXE (Pre-Boot Execution Environment) support USB booting support2.16 Operating Temperature and Temperature ControlThe maximum and minimum operating temperatures for the WAFER-LX are listed below. Minimum Operating Temperature: 0ºC (32°F) Maximum Operating Temperature: 60°C (140°F)A cooling fan and heat sink must be installed on the CPU. Thermal paste must besmeared on the lower side of the heat sink before it is mounted on the CPU. Heat sinksare also mounted on the northbridge and southbridge chipsets to ensure the operatingtemperature of these chips remain low.2.17 Audio CodecThe WAFER-LX has an integrated RealTek ALC203 codec.
