Chapter 1: Introduction 1-2 Chipset Overview Intel’s Grantsdale (915G) chipset, is comprised of two primary components: the Graphics Memory Controller Hub (GMCH) and the I/O Controller Hub (ICH6). The Grantsdale (915G) provides the performance and feature-set required for high-end single-processor desktop solutions.
P8SGA User’s Manual 1-3 PC Health Monitoring This section describes the PC health monitoring features of the P8SGA. The motherboard has an onboard System Hardware Monitor chip that supports PC health monitoring. Eight Onboard Voltage Monitors for the CPU Core, Chipset Voltage, +3.3V, +3.3V standby, + 5V, 1.5V, Vbat and ± 12V The onboard voltage monitor will scan these voltages continuously. Once a voltage becomes unstable, it will give a warning or send an error message to the screen.
Chapter 1: Introduction 1-4 Power Configuration Settings This section describes features of your motherboard that deal with power and power settings. Microsoft OnNow The OnNow design initiative is a comprehensive, system-wide approach to system and device power control. OnNow is a term for a PC that is always on but appears to be off and responds immediately to user or other requests.
P8SGA User’s Manual 1-5 Power Supply As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for processors that have high CPU clock rates of 1 GHz and faster. P8SGA accommodates 12V ATX power supplies. Although The most power supplies generally meet the specifications required by the CPU, some are inadequate. A 2 amps of current supply on a 5V Standby rail is strongly recommended.
Chapter 1: Introduction 1-6 Super I/O The disk drive adapter functions of the Super I/O chip include a floppy disk drive controller that is compatible with industry standard 82077/765, a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA logic. The wide range of functions integrated onto the Super I/O greatly reduces the number of components required for interfacing with floppy disk drives.

P8SGA User's Manual Introduction to Serial ATA (SATA) Serial ATA(SATA) is a physical storage interface. It uses a single cable with a minimum of four wires to create a point-to-point connection between devices. It is a serial link which supports SATA Transfer rates from 150MBps. Because the serial cables used in SATA are thinner than the traditional cables used in Parallel ATA(PATA), SATA systems have better airflow and can be installed in smaller chassis than Parallel ATA.
Chapter 2: Installation Supero Doctor III The Supero Doctor III program is a Web based management tool that supports remote management capability. It includes Remote and Local Management tools. The local management is called SD III Client. The Supero Doctor III program included on the CDROM that came with your motherboard allows you to monitor the environment and operations of your system. Supero Doctor III displays crucial system information such as CPU temperature, system voltages and fan status.
