chapter gives background informa- tion on the SBC-590. Sections include: • Card specifications • Board layout Chapter 1 General Information 1 CHAPTER Introduction The SBC-590 is an all-in-one single board Pentium computer with an on-board SVGA controller, with PCI-bus and ISA-bus support. It packs all the functions of an industrial computer with display capabili- ties on a single full-size card. The SBC-590 is fully PC/AT compati- ble, so your software will run without modifications. The on-board PCI-bus SVGA controller uses the ALG 2032 chipset with 1 MB shared memory. This chipset, used with the local PCI-bus, enables 32-bit graphic throughput and has a built-in Standard Feature Connector. These features make the SBC-590 particularly suited for graphics intensive applications. Another feature of the SBC-590 is the inclusion of a high speed local bus IDE controller. This controller supports (through ATA PIO) mode 3 and mode 4 hard disks, which enables data transfer rates in excess of 11 MB/sec. Up to four IDE devices can be connected, including large hard disks, CD-ROM drives, tape backup drives or other IDE devices. The built-in enhanced IDE controller provides a 4-layer 32-bit posted write-buffer and a 4-layer 32-bit read-prefetch- buffer to accomplish the IDE boost in performace improvements. On-board features also include two high-speed RS-232 serial ports with 16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy drive controller. In addition to the Pentium's 16 KB of on-chip cache memory, the SBC-590 comes with an extra 256 KB or 512 KB of second level memory on-board. If program execution is halted by a program bug or EMI, the board's 16-stage watchdog timer can automatically reset the CPU or generate an interrupt, provided the watchdog timer has been programmed in advance. This ensures reliability in unmanned or stand-alone systems. The SBC-590 supports 5V EDO DRAM. It also provides four 72-pin SIMM (Single In-line Memory Module) sockets for its on-board system DRAM. These sockets give you the flexibility to configure your system from 1 MB to 128 MB of DRAM using the most eco- nomical combination of SIMMs. 2 SBC-590 User's Manual Features • Accepts Intel Pentium 75-200 MHz CPUs and other compatible CPUs at 66/60/50/40 MHz (external clock speed) • Fully PC/AT-compatible PCI/ISA-bus CPU card • On-board 32-bit PCI-bus SVGA controller • Built-in, fast PCI enhanced IDE controller; supports four IDE devices (large hard disks, CD-ROM, tape backup, etc.) • Supports 5 V EDO DRAM and up to 128 MB of on-board DRAM • Supports pipeline burst SRAM module • Two high-speed serial RS-232 ports (16C550 UARTs with 16-byte FIFO); IRQ3, 4, or IRQ 10, 11 can be individually selected • One enhanced bidirectional parallel port; supports SPP/EPP/ECP • Watchdog timer (64 steps, 1 seconds per step) • On-board keyboard and PS/2 mouse connector • Connectors for PC/104 module expansion • "Green" function; supports power management • Supports a Feature Connector Chapter 1 General Information 3 Specifications • CPU: Intel Pentium 75-200 MHz CPUs and other compatible CPUs at 66/ 60/50/40 MHz (external clock speed) • Bus interface: ISA and PCI (PC/AT) bus • Data bus: 64 bit • Processing ability: 64 bit • Chipset: VT 82C575/82C576/82C577 • RAM memory: 1 MB to 128 MB.

B1 Setting jumpers You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you would connect either pins 1 and 2 or 2 and 3. 3 3 3 3 3 2 2 2 2 2 1 1 1 1 1 Open Open Open Open Open Closed Closed Closed Closed Closed Closed 2-3 Closed 2-3 Closed 2-3 Closed 2-3 Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 2 3 Open Open Open Closed Closed Closed Closed 2-3 Closed 2-3 Closed 2-3 Open Open Closed Closed Closed 2-3 Closed 2-3 A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representa- tive before you make any changes. Generally, you simply need a standard cable to make most connections. 12 SBC-590 User's Manual Safety precautions Warning! Always completely disconnect the power cord from your chassis whenever you are working on it. Do not make connections while the power is on, sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the CPU card. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis. Chapter 2 Installation 13 Installing the CPU The SBC-590 CPU card supports Intel Pentium 75~166 and other compatible CPUs at 66/60/50/40 MHz (external clock speed). The system's performance depends on the CPU you choose. You can install or upgrade the CPU in the board's ZIF socket by following the procedures outlined below. If your system has an existing CPU, you need to remove it before installing the new CPU. Removing a CPU 1. Pull the lever on the side of the ZIF socket out a little and raise it up as far as it will go. 2. Lift the CPU out. Installing the CPU 1. Make sure the ZIF socket lever is up as far as it can go. The Pin 1 position is at the arm corner. 2. Match Pin 1 on the CPU with the Pin 1 position on the ZIF socket. The pins on the three inner rings of the CPU should be aligned with the holes on the ZIF socket. 3. Insert the CPU. If it does not go in easily, lift the lever higher. 4. Press the lever down. The sliding plate will move forward to position the CPU. You will feel some resistance in the lever as the CPU is secured into place. When the CPU is properly installed, the lever will snap into place at the side of the ZIF socket. When you install a new CPU, you may have to adjust other settings on the board, such as CPU type, CPU clock and PCI speed, to accommodate it. Make sure that the settings are correct for your CPU. Improper settings may damage the CPU. 14 SBC-590 User's Manual CPU Clock Ratio Select (J1,J2) J1. J2 must be set to match the clok ratio of CPU. The chart below shows the proper jumper setting.

Quick Power On Self Test This option speeds up the Power-On Self Test (POST) conducted as soon as the computer is turned on. When enabled, BIOS shortens or skips some of the items during the test. When disabled, normal POST procedures assumes. Boot Sequence This function determines the sequence in which the computer will search the drives for the disk operating system (i.e. DOS). The default value is "A, C". C,A System will first search the hard drive, then the floppy drive. A,C System will first search the floppy drive, then the hard drive. Boot Up Floppy Seek During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360 KB type is 40 tracks while 720 KB, 1.2 MB, and 1.44 MB are all 80 tracks. Enabled BIOS searches the floppy drive to determine if it is 40 or 80 tracks. Note that BIOS cannot differentiate 720 KB, 1.2 MB, and 1.44 MB type drives as they are all 80 tracks. Disabled BIOS will not search for the floppy drive type by track number. Note that there will not be any warning message if the drive installed is 360 KB. Boot Up NumLock Status The default is "On". On Keypad boots up to number keys. Off Keypad boots up to arrow keys.
