However, rooms with humidity over 70%, and dusty or dirty areas are not appropriate. In addition, do not expose the system to any temperatures over +35°C or under +10°C. Make sure that the cables connecting the system to peripheral devices are not tight. Make sure that all power and connection cables are positioned so that they are not trip hazards. When you save data to your system`s hard disks or to a floppy disk, they are stored as magnetic information on the media. Make sure that they are not damaged by magnetic or electromagnetic fields. Because the electronics in your computer can be damaged by jarring, no mechanical devices should be placed on the same surface as the system. This is especially important for impact printers whose vibrations could damage the hard disk. ATTENTION In order to fully separate the system from current, the power cord must be removed from the wall outlet MAXDATA Fusion 6000 7 Connecting the system Rear Connectors Figure 1.

A list of qualified DIMMs will be made available. Note that all DIMMs are supported by design, but only fully qualified DIMMs will be supported. 11 MAXDATA Fusion 6000 Intel® 845E Chipset The Intel® 845E chipset consists of the following devices: · · · Intel® 82845E Memory Controller Hub (MCH) with Accelerated Hub Architecture (AHA) bus Intel® 82801BA I/O Controller Hub (ICH2) with AHA bus Intel® 82802AB Firmware Hub (FWH) The MCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the Accelerated Hub Architecture interface. The ICH2 is a centralized controller for the board's I/O paths. The FWH provides the nonvolatile storage of the BIOS. Intel® 82845E Memory Controller Hub (MCH) The MCH supports the data integrity features supported by the Pentium® Pro bus, including address, request, and response parity. The 845E chipset always generates ECC data while it is driving the processor data bus, although the data bus ECC can be disabled or enabled by BIOS. It is enabled by default. The MCH provides the following: · · An integrated Synchronous DRAM memory controller with auto detection of SDRAM. Support for ACPI Rev 1.0b compliant power management. Intel® 82801BA I/O Controller Hub (ICH2) The Intel® 82801BA ICH2 has these features: · · · · · 33 MHz Peripheral Component Interface (PCI) Local Bus slots supporting PCI specification, Rev 2.2.

Power management logic (ACPI Rev 1.0b compliant). Support for the System Management Bus routed to: - All PCI Slots - S5 wake from all PCI slots Real-Time Clock (with 256-byte battery backed CMOS RAM). Supports two Master/DMA devices. · · · · Intel® 82802AB Firmware Hub (FWH) The Intel® 82802AB Firmware Hub (FWH) includes a 4 megabit symmetrical flash memory device. Internally, the device is grouped into eight 64 KB blocks that are individually erasable, lockable, and unlockable. The FWH provides the following: · · System BIOS program Logic that enables protection for storing and updating of platform information 12 Description I/O Controller The SMSC LPC47M102 I/O Controller provides the following features: · · · · · · · · · · Low pin count (LPC) interface 3.3 V operation One serial port and one serial port header One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support Serial IRQ interface compatible with serialized IRQ support for PCI systems PS/2-style mouse and keyboard interfaces Interface for two 1.2 MB, 1.44 MB, or 2.88 MB diskette drives Intel® ligent power management, including a programmable wake up event interface PCI power management support Fan control: - Four fan control outputs - Four fan tachometer inputs The BIOS Setup program provides configuration options for the I/O controller. Serial Ports The MAXDATA Fusion 6000 System board has one serial port connector and one serial port header. The serial port A connector is located on the back panel. The serial port B header is located near the main power connector. The serial ports' NS16C550-compatible UART supports data transfers at speeds up to 115.2 kb/s with BIOS support. Parallel Port The 25-pin D-Sub parallel port connector is located on the back panel. In the BIOS Setup program, the parallel port can be set to the following modes: · · · · Output only (PC AT-compatible mode) Bi-directional (PS/2 compatible) EPP ECP Diskette Drive Controller The I/O controller supports two diskette drives that are compatible with the 82077 diskette drive controller and supports both PC-AT and PS/2 modes. Keyboard and Mouse Interface PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines to these connectors are protected with a PolySwitch circuit that, like a self-healing fuse, reestablishes the connection after an overcurrent condition is removed. NOTE The keyboard is supported in the bottom PS/2 connector and the mouse is supported in the top PS/2 connector. Power to the computer should be turned off before a keyboard or mouse is connected or disconnected. The keyboard controller contains the AMI keyboard and mouse controller code, provides the keyboard and mouse control functions, and supports password protection for power-on/reset. A power-on/reset password can be specified in the BIOS Setup program. MAXDATA Fusion 6000 13 Hardware Management Subsystem The Hardware Management features enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features, including the following: · · · Fan monitoring Thermal and voltage monitoring Chassis intrusion detection Hardware Management ASIC The Hardware Management ASIC provides low-cost instrumentation capabilities. The features of the component include: · · · · Internal ambient temperature sensing Remote thermal diode sensing for direct monitoring of processor temperature Power supply monitoring (+5 V, +3.3 V, +1.5 V, 3.3 VSB, and Vccp) to detect levels above or below acceptable values SMBus interface Fan Monitoring The Hardware Management ASIC provides four fan tachometer inputs. Monitoring can be implemented using Intel® LANDesk Client Manager or third-party software. Real-Time Clock, CMOS SRAM, and Battery The real-time clock provides a time-of-day clock and a multi-century calendar with alarm features. The real-time clock supports 256 bytes of battery-backed CMOS SRAM in two banks that are reserved for BIOS use. A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25º C with 3.3 VSB applied. The time, date, and CMOS values can be specified in the BIOS Setup program. The CMOS values can be returned to their defaults by using the BIOS Setup program. NOTE If the battery and AC power fail, custom defaults, if previously saved, will be loaded into CMOS RAM at power-on. 14 Description Legacy USB Support Legacy USB support enables USB devices such as keyboard, mice, and hubs to be used even when the operating system's USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. The MAXDATA Fusion 6000 System board has two USB 1.1 ports; one USB peripheral can be connected to each port. For more than two USB devices, an external hub can be connected to any of the ports. Two of the USB ports are implemented with stacked back panel connectors; the other two are accessible via the front panel USB header. The MAXDATA Fusion 6000 System board fully supports UHCI and uses UHCI-compatible software drivers. NOTE Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices. Legacy USB support operates as follows: 1. When the user applies power to the computer, legacy support is disabled. 2. POST begins. 3. Legacy USB support is enabled by the BIOS allowing the user to use a USB keyboard to enter and configure the BIOS Setup program and the maintenance menu. 4. POST completes. 5. The operating system loads. While the operating system is loading, USB keyboard and mice are recognized and may be used to configure the operating system. (Keyboard and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system's installation instructions. NOTE Legacy USB support is for keyboard, mice, and hubs only. Other USB devices are not supported in legacy mode. MAXDATA Fusion 6000 15 IDE Support IDE Interfaces The ICH2's IDE controller has two independent bus-mastering IDE interfaces that can be independently enabled. The IDE interfaces support the following modes: · · · · Programmed I/O (PIO): processor controls data transfer. 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/ sec. Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec. ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible. ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH2's ATA100 logic can achieve transfer rates up to 100 MB/sec. · NOTE ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling. The IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes. The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS. The MAXDATA Fusion 6000 System board supports Laser Servo (LS-120) diskette technology through the IDE interfaces. An LS-120 drive can be configured as a boot device by setting the BIOS Setup program's Boot menu to one of the following: · · ARMD-FDD (ATAPI removable media device ­ floppy disk drive) ARMD-HDD (ATAPI removable media device ­ hard disk drive) BIOS The MAXDATA Fusion 6000 System board uses an Intel®/AMI BIOS that is stored in the Firmware Hub (FWH) and can be updated using a disk-based program. The FWH contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. The MAXDATA Fusion 6000 System board supports system BIOS shadowing, allowing the BIOS to execute from 64-bit onboard write-protected system memory. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOS is identified as PT84510A.86B. When the MAXDATA Fusion 6000 System board's jumper is set to configuration mode and the system is powered-up, the BIOS compares the processor version and the microcode version in the BIOS and reports if the two match. PCI Auto Configuration The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Auto configuration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card. Auto configuration information is stored in ESCD format. 16 Description PCI IDE Support If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two PCI IDE connectors with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives. The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. To use ATA-66/100 features the following items are required: · · · An ATA-66/100 peripheral device An ATA-66/100 compatible cable ATA-66/100 operating system device drivers NOTE ATA-66/100 compatible cables are backward compatible with drives using slower IDE transfer protocols. If an ATA-66/100 disk drive and a disk drive using any other IDE transfer protocol are attached to the same cable, the maximum transfer rate between the drives is reduced to that of the slowest device. Language Support The BIOS Setup program and help messages are supported in two languages: US English and Spanish. Additional languages may be flashed in if desired (German, Italian, and French available). The default language is US English, which is present unless another language is selected in the BIOS Setup program. Custom Splash Screen During POST, an Intel® splash screen is displayed by default. This splash screen can be replaced with a custom splash screen. A utility is available from Intel® to assist with creating a custom splash screen. The custom splash screen can be programmed into the flash memory using the BIOS upgrade utility. Information about this capability is available on the Intel® Support World Wide Web site. Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled. CD-ROM and Network Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the BIOS Setup program, ATAPI CD-ROM is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot from the next defined drive. The network can be selected as a boot device. This selection allows booting from the onboard NIC or a network add-in card with a remote boot ROM installed. MAXDATA Fusion 6000 17 Booting Without Attached Devices For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present: · · · Video adapter Keyboard Mouse Fast Booting Systems with Intel® Rapid BIOS Boot These factors affect system boot speed: · · Selecting and configuring peripherals properly Using an optimized BIOS, such as the Intel® Rapid BIOS Intel® Rapid BIOS Boot Using the following BIOS Setup program settings reduces the POST execution time. In the Boot Menu: · · · Set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time. Disable Quiet Boot, which eliminates display of the logo splash screen. This could save several seconds of painting complex graphic images and changing video modes. Enabled Intel® Rapid BIOS Boot. This feature bypasses memory count and the search for a diskette drive. NOTE It is possible to optimize the boot process to the point where the system boots so quickly that the Intel® logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen. This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced Menu in the IDE Configuration Submenu of the BIOS Setup program). BIOS Security Passwords The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the system. A supervisor password and a user password can be set for the Setup menu and for booting the system, with the following restrictions: · The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing at the password prompt of Setup gives the user restricted access to Setup. If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered. Setting a user password restricts who can boot the system. The password prompt is displayed before the system is booted. If only the supervisor password is set, the system boots without asking for a password. If both passwords are set, you can enter either password to boot the system. · · 18 Description Table 4. Supervisor and User Password Functions Password Set Supervisor Mode Neither Supervisor only User only Can change all options (Note) Can change all options N/A User Mode Can change all options (Note) Setup Options None Password to Enter Setup None Supervisor Password During Boot None None Can change a Supervisor Password limited number of options Can change all options Enter Password Clear User Password User Supervisor or user User Supervisor or user Supervisor and Can change all user set options Can change a Supervisor Password limited number Enter Password of options Note: If no password is set, any user can change all Setup options. System Management BIOS (SMBIOS) SMBIOS is a System Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: · · · · BIOS data, such as the BIOS revision level Fixed-system data, such as peripherals, serial numbers, and asset tags Resource data, such as memory size, cache size, and processor speed Dynamic data, such as event detection and error logging Non-Plug and Play operating systems, such as Windows® NT, require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. Power Management Features Power management is implemented at several levels, including: · · Software support through Advanced Configuration and Power Interface (ACPI) Hardware support: - Power connector - Fan connectors - LAN wake capabilities - Instantly Available PC technology - Resume on Ring - Wake from USB - Wake from PS/2 devices - Power Management Event (PME#) wake-up support MAXDATA Fusion 6000 19 Wake on LAN Technology Network adapters that are PCI 2.2 compliant assert the wake-up signal using the PCI bus signal PME# (pin A19 on the PCI bus connectors). CAUTION For Wake on LAN technology, the 5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing Wake on LAN technology can damage the power supply. CAUTION If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the system board may lose register settings stored in memory, etc. Wake on Ring The operation of Wake on Ring can be summarized as follows: · · · Powers up the system from the ACPI S5 state. Modem must support PME. Requires two calls to access the system: - The first call powers up the system - The second call enables access (when the appropriate software is loaded) For external modems, hardware on the system board monitors the ring indicate (RI) input of the serial port. · Resume on Ring The operation of Resume on Ring can be summarized as follows: · · · · Resumes operation from the ACPI S1. Requires only one call to access the system. Detects incoming call similarly for external and internal modems; does not use the Wake on Ring connector.
