Chapter 1: Introduction CPU Overheat LED and Control This feature is available when the user enables the CPU overheat warning function in the BIOS. This allows the user to define an overheat tempera- ture. When this temperature is exceeded, both the overheat fan and the warning LED are triggered. Introduction System Resource Alert This feature is available when used with Intel's LANDesk Client Manager (optional). It is used to notify the user of certain system events. For example, if the system is running low on virtual memory and there is insuf- ficient hard drive space for saving the data, you can be alerted of the potential problem.
Hardware BIOS Virus Protection The system BIOS is protected by hardware so that no virus can infect the BIOS area. The user can only change the BIOS content through the flash utility provided by SUPERMICRO. This feature can prevent viruses from infecting the BIOS area and destroying valuable data. Auto-Switching Voltage Regulator for the CPU Core The auto-switching voltage regulator for the CPU core can support up to 20A of current and auto-sense voltage IDs ranging from 1.3V to 3.5V. This will allow the regulator to run cooler and thus make the system more stable. 1-4 ACPI Features ACPI is an acronym for Advanced Configuration and Power Interface.
The ACPI specification defines a flexible and abstract hardware interface that provides a standard way to integrate power management features through- out a PC system, including its hardware, operating system and application software. This enables the system to turn on and off peripherals such as CD-ROMs, network cards, hard disk drives and printers automatically. This also includes consumer devices connected to the PC such as VCRs, TVs, telephones and stereos. In addition to enabling operating system-directed power management, ACPI provides a generic system event mechanism for Plug and Play and an oper- ating system-independent interface for configuration control.
