Chapter 1: Introduction 1-2 Chipset Overview The H8DSR-8/H8DSR-i serverboard is based on a ServerWorks chipset composed of two main components: the HT-2000 HyperTransportTM SystemI/OTM controller and the HT-1000 HyperTransportTM SystemI/OTM Hub. The HT-2000/1000 chipset provides high performance, scalability and reliability. Its HyperTransport architecture reduces IO bottlenecks to improve overall system performance. System memory controllers are integrated into the processors to decrease latency.
H8DSR-8/H8DSR-i User’s Manual 1-3 PC Health Monitoring This section describes the PC health monitoring features of the H8DSR-8/H8DSRi. The serverboard has an onboard System Hardware Monitor chip that supports PC health monitoring. Onboard Voltage Monitors for the CPU core voltages, +2.5V, +5V, +1.2V, ±12V and Battery Voltage 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 the features of your serverboard 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.
H8DSR-8/H8DSR-i 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. The H8DSR-8/H8DSR-i accommodates 12V ATX power supplies. Although most power supplies generally meet the specifications required by the CPU, some are inadequate. A 2 amp 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.

H8DSR-8/H8DSR-i User's Manual 2-3 Mounting the Serverboard into a Chassis All serverboards and motherboards have standard mounting holes to fit different types of chassis. Make sure that the locations of all the mounting holes for both the serverboard and the chassis match. Although a chassis may have both plastic and metal mounting fasteners, metal ones are highly recommended because they ground the serverboard to the chassis. Make sure that the metal standoffs click in or are screwed in tightly. 1.
Chapter 2: Installation Support The H8DSR-8/H8DSR-i supports single or dual-channel, registered ECC DDR400/333/266/200 SDRAM.
