Sections include: • Specifications • Board layout • Dimensions Chapter 1 General Information 1 CHAPTER Introduction The PCM-4894 is an all-in-one single board 486 computer with an onboard flat panel/CRT SVGA controller and PCI Ether- net interface. It offers all the functions of an industrial comput- er and its display capabilities on a single board, but fits in the space of a 5.25" floppy drive (only 5.75" x 8"). This means the PCM-4894 is your absolute best solution for embedded applica- tions. The onboard PCI-bus, flat panel/CRT SVGA controller uses the CHIPS 65550 chipset with up to 2 MB of video memory (on- board 1MB). This chipset, used with the local PCI-bus, enables 32-bit graphic throughput at up to 33 MHz. Excellent for display- intensive applications, it supports various LCD types including TFT, STN, B/W, and EL. The onboard Ethernet Realtek RTL 8029AS PCI bus Ethernet controller supports remote boot ROM functions. The PCM-4894 supports the M-Systems DiskOnChip 2000 (optional) which is a new generation of high performance single- chip Flash Disk. It provides a Flash Disk (as a BIOS expansion) which does not require any bus, slots, or connectors. It is also the optimal solution for Single Board Computers because of its small size, easy integration, plug-and-play functionality, and its low power consumption. The DiskOnChip is available in capacities from 2MB to 72MB and fits in a standard 32-pin DIP socket. Another feature of the PCM-4894 is the inclusion of a high speed, local bus IDE controller. This controller supports (through ATA PIO) mode 3 and mode 4 hard disks, enabling data transfer rates in excess of 11 MB/second. Up to two 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 boost IDE performance. 2 PCM-4894 User Manual Specifications Standard SBC functions CPU: AMD 5X86-P75 (486DX5-133) SQFP BIOS: Award 128KB FLASH BIOS Chipset: ALI 1487/1489 Super I/O Chipset: WINBOND83877TF nd nd 2 Level Cache: On board 128KB 2 level cache.

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 2 1 Open Closed Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 2 3 Open Closed 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 represen- tative before you make any changes. 12 PCM-4894 User 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 because 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 DRAM (SIMMs) The PCM-4894 CPU card provides two 72-pin SIMM (Single In- line Memory Module) sockets and supports between 4MB and 64MB. When installing SIMMs, make sure that Bank 1 is filled first. Installing SIMMs Note: that the modules can only fit into a socket one way. 1. Insert the memory module into the socket at a moderate angle. 2. Push the module toward the vertical posts at both ends of the socket until the module is upright and the retaining clips at both ends of the module click into place. When positioned correctly, the pins on top of the vertical posts should corre- spond to the circular holes on the ends of the module. 3. Repeat steps 1 and 2 for each module you install. Removing SIMMs If you need to remove a SIMM, follow the procedures below: 1. Supporting the SIMM with a finger, use a pen or a similarly shaped object and press one retaining clip straight down. 2. Repeat for the other side. When released, the retaining clips will push the SIMM up and out of its upright position. 3. Carefully pull the SIMM out of the socket with your fingers. 4. Repeat the above steps for each module you remove. 14 PCM-4894 User Manual Ethernet connector (CN1) The Ethernet connects to the PCM-4894 via an adapter cable to a 10-pin polarized header (CN1). For 10Base-T RJ-45 operation, an adapter cable converting CN1 into a standard RJ-45 jack is required.

The card comes with a 40-pin flat piggyback cable. This cable has one 44- pin 2.0mm pitch and two identical 40-pin flat-cable connectors. Connecting the hard drive Usually, wire number 1 on the cable is red or blue, and the other wires are gray. 1. Connect one end of the cable to the IDE connector. Make sure that the red (or blue) wire corresponds to pin 1 on the connector, which is labeled on the board. 2. Plug the other end of the cable to the Enhanced IDE hard drive, with pin 1 on the cable corresponding to pin 1 on the hard drive. (See your hard drive's documentation for the location of the connector.) Unlike floppy drives, you can make the connections with any of the connectors on the cable. If you install two drives, you will need to set one as the master and one as the slave. You do this using jumpers on the drives. If you install just one drive, set it as the master. 18 PCM-4894 User Manual Pin assignments The following table lists the pin numbers and their respective signals: IDE Connector (CN4) Pin Signal Pin Signal 1 Reset 2 GND 3D7 4 D8 5D6 6 D9 7 D5 8 D10 9D4 10 D11 11 D3 12 D12 13 D2 14 D13 15 D1 16 D14 17 D0 18 D15 19 GND 20 N.C. 21 N.C. 22 GND 23 IOW 24 GND 25 IOR 26 GND 27 IORDY 28 NC 29 N.C. 30 GND 31 IRQ 14 32 -I/O CS16 33 A1 34 N.C. 35 A0 36 A2 37 CS0 38 CS1 39 -ACT 40 GND 41 +5V 42 +5V 43 NC 44 GND Chapter 2 Installation 19 Floppy drive connector (CN5) You can attach up to two floppy disks to the PCM-4894's on- board controller.

Chapter 3 Award BIOS Setup 33 CHAPTER System test and initialization These routines test and initialize board hardware. If the routines encounter an error during the tests, you will either hear a few short beeps or see an error message on the screen. There are two kinds of errors: fatal and nonfatal. The system can usually continue the boot up sequence with nonfatal errors. Nonfatal error messages usually appear on the screen along with the following instructions: press to RESUME Write down the message and press the F1 key to continue the bootup sequence. System configuration verification These routines check the current system configuration against the values stored in the card’s CMOS memory. If they don’t match, the program outputs an error message. You will then need to run the BIOS setup program to set the configuration information in memory. There are three situations in which you will need to change the CMOS settings: 1. You are starting your system for the first time. 2. You have changed the hardware attached to your system. 3. The CMOS memory has lost power and the configuration information has been erased. 34 PCM-4894 User Manual Award BIOS setup Entering setup Power on the computer and press immediately.

However, it depends on the CPU/chipset design. Quick Power On Self Test This category speeds up Power On Self Test (POST) after you power up the computer. If it is set to Enabled, BIOS will shorten or skip some check items during POST. Boot Sequence This category determines which drive to search first for the operating system. Swap Floppy Drive This item allows you to swap the floppy drive assignments so that drive A is treated as drive B and drive B is treated as drive A under DOS. The default setting is Disabled. Boot Up Floppy Seek During POST, the BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360KB type is 40 tracks while 760KB, 1.2MB, and 1.44MB are all 80 tracks. Boot Up NumLock Status This allows you to determine the default state of the numeric keypad on an IBM-compatible extended keyboard. Boot Up System Speed This allows you to determine the Boot Up Speed. The choices are High/Low. Chapter 3 Award BIOS Setup 39 Gate A20 Option This entry allows you to select how gate A20 is handled. Gate A20 is a device used to address memory above 1 MB. Initially, gate A20 was handled via a pin on the keyboard. Today keyboards still provide this support, however it is more common and much faster for the system chipset to provide support for gate A20. The choices are thus: Normal and Fast. Security Option This category allows you to limit access to the system. The choices are System: which requires a password at boot up and Setup: which only requires a password to access the setup utility. Video BIOS Shadow Determines whether the video display card BIOS will be copied into system DRAM in order to increase display speed and is required for system performance. However, it is optional depending on the chipset design. The default setting is Enabled. Shadowing Address Ranges The next 3 lines, from C8000-CBFFF Shadow to DC000-DFFFF Shadow are address ranges for shadowing other expansion card ROMs. If there are any expansion cards with ROMs installed in your system, you have to know the address range they use in order to shadow them specifically. The default setting for all of these is Disabled. 40 PCM-4894 User Manual CHIPSET features setup By choosing the BIOS FEATURES SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed. The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. CHIPSET features setup This section allows you to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as DRAM and the external cache. It also coordinates communica- tions between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered. The default settings have been chosen because they provide the best operating conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system. Because of the complexity and technical nature of some of the options, not all of the options are described here. Chapter 3 Award BIOS Setup 41 Power management setup By choosing the POWER MANAGEMENT SETUP option from the initial SETUP SCREEN menu, the screen below is displayed. The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. Power management setup Power Management Power management lets you set up your computer to save electricity when it is not actively in use by putting the system into progressively greater power saving modes. In the power manage- ment scheme there are four system states which proceed in the following sequence: Normal � Doze � Standby � Suspend 42 PCM-4894 User Manual There are four selections for Power Management (PM): Disabled Turns off PM Max Saving Maximized power saving by activating maximum power saving settings after one minute of system inactivity. Min Saving Produces less power saving by activating moderate power saving settings after one hour of system inactivity. User Defined You set the power saving options manually. With the exception of Disabled, three of the above selections have "fixed-mode" settings. Therefore, when PM is set to Disabled, some items which are predefined will become unmodi- fiable. PM Control by APM When this is set to Yes, the Advanced Power Management feature in Microsoft Windows controls power management operation. The default setting is No. Video Off Option User can select 4 different modes for turning off the video. The modes are a function of the PM mode of the computer. The choices are All Modes�Off, Always On, Suspend�Off, and Susp, Stby�Off. The table below summarizes the behavior of the monitor in relation to the four PM modes. PM Mode Monitor Behavior All Modes Off - Always On Suspend Off Susp, Stby Off For example, if you choose Suspend�Off, then the monitor will turn off if the computer is in the Suspend PM mode. Chapter 3 Award BIOS Setup 43 Video Off Method This governs monitor power saving by controlling how power management blanks the monitor screen. The default setting blanks the screen and turns off vertical and horizontal scanning and requires a monitor with "green" features. If you don't have this type of monitor, use the Blank option. DPMS (Display Power Management System) allows the BIOS to control the video display card if the card has the DPMS feature. V/H SYNC+Blank (Default) BLANK (non-green monitor, less saving) DPMS (Display card must support DPMS) Modem Use IRQ If you have a modem installed in your system, you can enter which IRQ it is using so that APM can control it. HDD Power Down When enabled and after the selected time of system inactivity, the hard disk drive will be powered down while all other devices will remain active. Doze Mode This sets the period of system inactivity after which the system goes into Doze mode, the most limited power saving state. The settings range from 10 seconds to 1 hour and can be set manually when power management is in User Define mode. The default setting is Disabled. When the system goes into power saving mode, power management will skip to the next mode in the sequence if this is disabled. 44 PCM-4894 User Manual Standby Mode This sets the period of system inactivity after which the system goes into Standby mode, the intermediate power saving state. The settings range from 10 seconds to 1 hour and can be set manually when power management is in User Define mode. The default setting is Disabled. When the system goes into power saving mode, power management will skip to the next mode in the sequence if this is disabled. Suspend Mode This sets the period of system inactivity after which the system goes into Suspend mode, the maximum power saving state. The settings range from 10 seconds to 1 hour and can be set manually when power management is in User Define mode. The default setting is Disabled. When the system goes into power saving mode, power management will skip to the next mode in the sequence if this is disabled. Chapter 3 Award BIOS Setup 45 PM Events PM events are I/O events whose occurrence can prevent the system from entering a power saving mode or can awaken the system from such a mode. In effect, the system remains alert for anything which occurs to a device which is configured as En- abled, even when the system is in a power down mode. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ (Interrupt Request) to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service. The follow- ing is a list of IRQs, which can be disabled: • COM Ports Activity • LPT Ports Activity • HDD Ports Activity • VGA Activity • IRQ3 (COM 2) • IRQ4 (COM 1) • IRQ5 (LPT 2) • IRQ6 (Floppy Disk) • IRQ7 (LPT 1) • IRQ8 (RTC Alarm) • IRQ9 (IRQ2 Redir) • IRQ10 (Reserved) • IRQ11 (Reserved) • IRQ12 (PS/2 Mouse) • IRQ13 (Coprocessor) • IRQ14 (Hard Disk) • IRQ15 (Reserved) 46 PCM-4894 User Manual PCI configuration setup By choosing the PCI CONFIGURATION SETUP option from the initial SETUP SCREEN menu, the screen below is displayed. The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. PCI configuration setup This section describes configuring the Peripheral Component Interconnect (PCI) bus system which allows I/O devices to operate at speeds nearing the speed of the CPU when communi- cating with its own special components. This section covers some very technical items and it is strongly recommended that only experienced users make any changes to the default settings. PnP BIOS Auto-Config The Award Plug and Play BIOS has the capacity to automatically configure all of the boot and Plug and Play compatible devices. However, this will only work if you are running a Plug and Play TM . operating system such as Windows 95 Chapter 3 Award BIOS Setup 47 Reset Configuration Data This item allows you to reset the configuration data. PCI IRQ Activated By This sets the method by which the PCI bus recognizes that an IRQ service is being requested by a device. Under all circumstances, you should retain the default configuration unless advised by your system manufacturer. The choices are Level/Edge. PCI IDE IRQ Map To This allows you to configure your system to the type of IDE disk controller in use. The more apparent difference is the type of slot being used. If you have equipped your system with a PCI controller, changing this allows you to specify which slot has the controller and which PCI interrupt (A, B, C, D) is associated with the connected hard drives. This setting refers to the hard disk drive itself, rather than individual partitions. Selecting PCI Auto allows the system to automatically determine how your IDE disk system is configured. 48 PCM-4894 User Manual Load BIOS defaults / Load setup defaults LOAD BIOS DEFAULTS loads the default system values directly from ROM. The BIOS DEFAULTS provides the most stable settings, though they do not provide optimal performance. LOAD SETUP DEFAULTS, on the other hand, provides for maximum system performance. If the stored record created by the setup utility becomes corrupted (and therefore unusable), BIOS defaults will load automatically when you turn the PCM-4894 on.

The onboard VGA adapter is based on the CHIPS VGA Flat Panel/CRT controller and is fully IBM VGA compatible. This controller offers a large set of extended functions and higher resolutions. If you intend to use your VGA adapter in standard VGA modes only, you do not need to install any of these drivers. Since your VGA adapter is fully compatible, it does not require any special drivers to operate in standard modes. The purpose of the enclosed software drivers is to take advantage of the extended features of the CHIPS VGA Flat Panel/CRT controller. Hardware configuration Some of the high-resolution drivers provided in this package will work only in certain system configurations. If a driver does not display correctly, try the following: 1. Change the display controller to CRT-only mode, rather than flat panel or simultaneous display mode. Some high-resolution drivers will display correctly only in CRT mode. 2. If a high-resolution mode is not supported on your system, try using a lower-resolution mode. For example, 1024 x 768 mode will not work on some systems, but 800 x 600 mode is supported on most. 52 PCM-4894 User Manual Necessary prerequisites The instructions in this manual assume that you understand elementa- ry concepts of MS-DOS and the IBM Personal Computer.
