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 (op- tional). 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 insufficient 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 current and auto-sense voltage IDs ranging from 1.4V to 3.5V. This will allow the regulator to run cooler and thus make the system more stable. 1-5 ACPI/PC 98 Features ACPI stands for Advanced Configuration and Power Interface.
The ACPI speci- fication defines a flexible and abstract hardware interface that provides a stan- dard way to integrate power management features throughout a PC system, including its hardware, operating system and application software. This enables the system to automatically turn on and off peripherals such as CD-ROMs, network cards, hard disk drives and printers. 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 pro- vides a generic system event mechanism for Plug and Play and an operating system-independent interface for configuration control.
ACPI leverages the Plug and Play BIOS data structures while providing a processor architecture-indepen- dent implementation that is compatible with both Windows 98 and Windows NT 1-11
