SC815E Endura Motherboard Product Manual 1 Overview The SC815E is a microATX form factor motherboard based around an Intel Celeron or Pentium III processor and an Intel 815E family chipset. It integrates video, audio, system monitoring and Ethernet on a 9.0 x 7.5-inch board and is targeted at the embedded PC technology market. Its small size also enables it to be used in a FlexATX chassis.

SC815E Endura Motherboard Product Manual Configuration The majority of the configuration of the motherboard is done through the Setup utility built into the BIOS – discussed later in this document. There is, however, one jumper that controls the operation of the motherboard as described below. Operating mode Normal Configure...
SC815E Endura Motherboard Product Manual 1.4.2 Front Panel Connections The primary controls and indicators for the motherboard are connected via the front panel connector using either a single ribbon cable to a 'front panel' assembly, or using a number of small PC- standard connectors.
For best performance, use PC133 modules with a 133MHz bus processor. When using a 100MHz bus processor, the module will always operate at 100MHz regardless of type. See the Manuals, Drivers & BIOS section on the RadiSys web site at www.radisys.com for a list of memory modules that have been tested with this product.

SC815E Endura Motherboard Product Manual 2.4.1 System Memory Allocation The video controller does not have dedicated frame buffer memory but instead makes use of system memory for all its needs. This must be taken into account when the amount of system memory is chosen.
SC815E Endura Motherboard Product Manual IDE Drives Two independent bus-mastering IDE interfaces are provided, each supporting ATA modes up to UltraATA/100. The following drive types are supported. • ATA hard disks up to UltraATA/100 speeds • ATAPI devices such as CD-ROMs •...
SC815E Endura Motherboard Product Manual 2.9.3 Infra-red Support The SC815E motherboard supports an IrDA compliant infra-red interface via the front panel header. An IR transceiver must be added such as the Hewlett Packard HSDL-3201 or the HSDL-3610 device. The IR port shares the serial port 2 channel and thus the two ports cannot be used simultaneously.
SC815E Endura Motherboard Product Manual 2.12 CMOS RAM & RTC The chipset integrates a Motorola MC146818A compatible real-time clock (RTC) and 256 bytes of CMOS RAM that is used by the BIOS to store configuration information. A replaceable primary lithium coin cell or, optionally, a Super Cap backs up both the RTC and the CMOS RAM. The former provides for approximately 5 years of unpowered backup.
SC815E Endura Motherboard Product Manual 2.14 System management The SC815E motherboard includes hardware system management functions integrated into the National Semiconductor PC87366 Super I/O (SIO) device. They monitor system voltages, motherboard and CPU temperatures, fan speed and control system fans. The following sections describe this in more detail.
SC815E Endura Motherboard Product Manual 2.14.2 Temperature Monitoring There are two temperature sensors on the motherboard. The first measures the motherboard temperature. Since the sensor is contained within the SIO, this will be a localized reading dominated by the motherboard surface temperature around the SIO component. The second temperature sensor is located on the processor die and thus accurately measures the local die temperature.
SC815E Endura Motherboard Product Manual 2.15 Power management The SC815E motherboard implements a number of power management features with software support for APM and ACPI. Where an operating system does not support ACPI, the motherboard defaults to using APM. An APM driver is required by the operating system in order to take advantage of the APM power management features.
The code is built from a number of software and data modules that can be customized and assembled with a software tool that can be provided by RadiSys. Software to support BIOS updates and crisis recovery is also available - see the Manuals, Drivers & BIOS section on www.radisys.com...
