IMMEDIATELY OBVIOUS, ENVIRONMENT. ELECTRONIC DEVICES, THE IS ESD DAMAGE IS NOT ALWAYS IN THAT IT CAN CAUSE A PARTIAL BREAKDOWN IN SEMICONDUCTOR DEVICES THAT MIGHT NOT IMMEDIATELY RESULT IN A FAILURE .
EPC-33/34 Hardware Reference 2 2 Figure 2-1. Location of EPC-33/34 Jumpers. BIOS Jumpers There are three BIOS jumpers and one video jumper that may or may not be required before you install or mount the EPC-33/34. JP4 BIOS Boot Block write enable. This jumper must be installed in order to write to the BIOS Boot Block. Note that JP5 must also be enabled to write to the BIOS. JP5 BIOS write enable.
Installation and Configuration JP1, JP2, and JP3 are read by the video BIOS to select which of the six LCD flatpanel options will be used. Connecting an unsupported LCD flat-panel will produce unpredictable results. If the system BIOS detects that a flat panel and a VGA monitor are both connected to the system, then the video BIOS is initialized for the VGA monitor. The flat panel can then be turned on using the CLMODE software described in Appendix E.
EPC-33/34 Hardware Reference Mounting Holes 2 2 Six mounting holes are positioned on the PCB to allow for alternate mounting of the EPC-33/34 in something other than an ISA-bus chassis. These holes are located near the corners of the board and in the middle of the board top and bottom edges. Four of the holes are positioned to also be used as mounting holes for PC/104 module(s). The locations of the mounting holes are shown below. All dimensions are in inches. Figure 2-2. EPC-33/34 Dimensions.
Installation and Configuration 2 Figure 2-3. EPC-33/34 Layout. It may be necessary to remove the PC mounting bracket from the EPC-33/34 before mounting flat on a surface. ISA-bus Passive Backplane Mechanically, the EPC-33/34 conforms to all outline requirements of the ISA-bus. The card is 9.5” long (measured from the inside of the end plate) by 4.2” tall including the card edge connector. * MAKE SURE SYSTEM POWER IS OFF. THE EPC-33/34 CANNOT BE INSERTED INTO OR REMOVED FROM A LIVE SYSTEM .
EPC-33/34 Hardware Reference 2 2 Insertion of the EPC-33/34 into an ISA-bus chassis or a passive backplane is straightforward. Remove a blank panel from the chassis and insert the EPC33/34 into the backplane card connector. Firmly press the EPC-33/34 down to ensure that the module is properly seated in the backplane. Before Powering Up Once the unit is mounted or installed, you are ready to connect cables and peripherals as needed. Refer to Figure 2-3 if necessary.
Installation and Configuration During the setup and configuration of the EPC-33/34, a monitor and keyboard are required. A hard drive is recommended. Whenever a hardware reset of the EPC occurs the system performs a power-on selftest (POST). The POST displays information showing the status of the BIOS selftest. In the case below, floppy drive A: is not configured correctly. The screen image displays approximately as shown. PhoenixBIOS Version 4.04 Copyright 1985-1995 Phoenix Technologies Ltd.
EPC-33/34 Hardware Reference BIOS Setup Screens 2 2 The EPC-33/34's BIOS contains a Setup function to display and alter the system configuration.

The EPC-34 uses the 100 MHz IntelDX4 CPU.
EPC-33/34 Hardware Reference Memory The EPC-33/34 supports one bank (a bank is a single- or double-sided SIMM) of 70ns fast page mode DRAM installed in a 72 pin SIMM socket. The SIMM parts used on the EPC-33/34 are 3.3 volt versions of sizes 1Mx32 (4MB), 2Mx32 (8MB), 4Mx32 (16MB) and 8Mx32 (32MB). The EPC-33/34 does not use parity DRAM. 3 3 After power on reset, the BIOS finds and sizes the memory present in the system.
Theory of Operation BIOS Flash EPROM The main IBM-compatible BIOS and video BIOS resides in an Intel Flash device. It is based on the Phoenix NuBIOS 4.04 code base. It includes the video BIOS, supplied by Cirrus Logic, and support for flat panel displays. The BIOS supports a set of six different flat panel displays. Refer to Appendix D for more information.
EPC-33/34 Hardware Reference The VGA controller provides the following set of output connectors: 1. 2. 3. 4. 3 3 A 15-pin D-sub connector on the AT bracket to connect to a VGA monitor. A 10-pin .100” pitch shrouded header which carries the same signals as the 15pin D connector. A 26-pin .100” pitch shrouded header to provide the feature connector interface. A 44-pin 2.0mm pitch shrouded header to connect flat panel displays.
Theory of Operation SRAM disk subsystem Two 128Kx8 SRAM devices may be factory-installed on the EPC-33/34. This SRAM is not located in the processor's memory address space; it is accessed indirectly through I/O reads and writes. Single byte I/O writes to 0x380-0x382 are saved in latches that set up the lower, middle, and high address bits that drive the SRAM’s address lines. I/O reads/writes to 0x384 access the SRAM data at the address stored in the latches.
EPC-33/34 Hardware Reference Address 0x389 0x38A 0x38B 3 3 Flash Disk Registers: D7-D4 D3-D0 Flash address A19-A16 Flash address A15 - A12 unused Flash address A23 - A20 unused Memory Window Size select A fourth register is used to provide control of the programming voltage to the Flash disk. This register is located at I/O port 0x38C and uses only one bit. When this bit is set to 1, the programming voltage is enabled. A 0 in this bit disables all write operations to the Flash disk.
Theory of Operation Watchdog timer A watchdog timer function is included to provide either an NMI or a RESET signal to the CPU in the event that software loses control of the system. A register is present that enables or disables the watchdog timer function and allows the selection of different timeout periods. The register returns the value FF when read.
EPC-33/34 Hardware Reference The ISA-bus signals are provided by the PicoPower PC/AT chipset. The buffer strengths, Iol and Ioh, on the bus are 12mA. The clock speed of the ISA-bus is set to approximately 8 MHz.
Theory of Operation Miscellaneous functions Keyboard controller A PC-compatible keyboard controller is provided on the board. Connection to it is made with a 6-pin mini-DIN circular connector, the type used in PS/2 designs and in other RadiSys CPU designs. This connector is located at the bottom of the AT bracket along the back edge of the circuit board. The keyboard connections are also provided in the test connector which is used in manufacturing test.
EPC-33/34 Hardware Reference Diode and/or resistor protection is employed in accordance with UL1950/EN0950 requirements to prevent damage from reverse current. Speaker A very small speaker (0.5" [12.7 mm] maximum) is installed on the PCB and connected to the standard PC "beep" generation circuit. It is expected that in highnoise situations a larger external speaker would be connected. 3 3 The external speaker is driven with a 5V P-P square-wave signal, with current limiting resistors.
Theory of Operation Watchdog Timer An output pin is provided which carries the TIMEOUT signal from the watchdog timer.
EPC-33/34 Hardware Reference Resetting the EPC There are a number of ways to reset (reboot) the EPC. Power-off, Power-on This causes the entire system to reset. The system runs the power-on selftests and reboot the operating system. 3 3 External Reset Input The external reset input causes the EPC-33/34 to perform a hardware reset. The system runs the power-on self-tests and reboot the operating system.
Theory of Operation Power Requirements In most applications, the EPC-33/34 operates on 5V DC power only. The voltage required is between 4.75 and 5.25 volts. +12V must be supplied via the ISA-bus or the power connector to erase or program the FLASH devices, including the BIOS. +5V may be supplied either via the ISA-bus edge connector, the PC/104 bus header, or the power connector. Care must be taken that the maximum current ratings of the connectors are not exceeded.
EPC-33/34 Hardware Reference Parallel Port The parallel port is located in a user-definable I/O address range (278, 3BC, or 378). Parallel port interrupts are signaled using IRQ7. Connection to this port is made via a header connector on the board that is shared with the COM2 serial port. The parallel port is bi-directional and since it conforms to IEEE 1284-I, the parallel port supports ECP modes.

Appendix C Ethernet This Appendix describes how to configure the Ethernet adapter on the EPC-33/34, including how to run the AUTOSET software and how to configure the Ethernet driver appropriate to your operating system. AUTOSET Software The AUTOSET program is used to configure the Ethernet controller. Since this may be set up by your supplier, you may never be required to use this program.
EPC-33/34 Hardware Reference The Ethernet 1 of 2 distribution diskette contains the setup program AUTOSET , and a collection of drivers for various network interfaces and operating systems. Ethernet 2 of 2 contains additional drivers. The installation program assumes you have DOS in your PATH statement. Using the AUTOSET C C Make sure that network software is NOT currently running on the computer system. If network software is running, reboot or unload the network software.
Appendix C - Ethernet 5. 6. Select the Physical Media cabled up: only 10BaseT is available for the EPC-33/34. Select the Adapter architecture. Use "I/O Port" for NE2000 mode, or use "Shared Memory" for Western Digital mode. 7. Skip the Boot PROM prompt. It does not apply to the EPC-33/34. 8. Save the configuration to the on-board memory only if your system is currently not connected to the network.
EPC-33/34 Hardware Reference I/O Base Address The Ethernet controller uses 32 bytes in I/O space. The I/O Base Address must be selected using the AUTOSET program. The AUTOSET program can only access the Ethernet controller when the I/O space occupied by the Ethernet controller does not conflict with I/O space previously assigned. In addition, the network interface drivers used with the Ethernet controller must use the same I/O base address parameter as the Ethernet controller.
Appendix C - Ethernet Note that the area excluded may be greater than that required by the Ethernet controller due to other system requirements. If you are unsure how to make these changes, refer to the Microsoft DOS User's Guide and Reference and Microsoft Windows Operating System manuals. Interrupts Use the tab key to scroll through the displayed options and select one of the listed interrupts. Note that AUTOSET lists all interrupts, not simply those that are available.
EPC-33/34 Hardware Reference Boot PROM (Ignore this prompt. The EPC-33/34 does not support the boot PROM option of AUTOSET .) Configuring Additional Ethernet Controllers C C To configure multiple Ethernet controllers for use in a single EPC, each Ethernet controller must be inserted in the system and configured, one at a time , before inserting the next Ethernet controller.
Appendix C - Ethernet The following displays while several options are checked: Network Interface Controller (12-byte node address).............. OK Buffer Memory Check............................................................ OK Check Cable Connection (Cable Connected) .......................... OK Interrupt Assignment (5)........................................................ OK Boot PROM Check (No Boot PROM)..................................... OK Press ESC to return to the previous menu.
EPC-33/34 Hardware Reference No NIC. DMA Failure These messages display when a fault is detected in the AT/LANTIC chip on the Ethernet controller. This is a fatal hardware error. Contact RadiSys Technical Support. Incorrect PROM ID Byte C C This message displays when there is a hardware problem in the EEPROM. I/O mode is thus disabled. Contact RadiSys Technical Support.
Appendix C - Ethernet Ethernet Drivers After the EPC-33/34 is installed, cabled and configured, follow the instructions in this chapter to configure the network interface drivers. The distribution diskettes supplied with the EPC-33/34 contain drivers for IPX, ODI, NDIS and a packet driver under DOS/Windows and OS/2. Also included are complete instructions for using the AUTOSET software. The majority of users running DOS/Windows select the ODI driver in 16-bit mode, if supported by their network software.
EPC-33/34 Hardware Reference The NE2000.COM driver supplied on the EPC-33/34 distribution diskettes is preconfigured for use with the Ethernet 802.3 interface. If your network requires operating multiple protocols on top of a single card, use the ECONGIF program provided by Novell to change the NE2000.COM interface setting to Ethernet II. C C The ATLANIC.COM driver is used in 16-bit Western Digital mode with the IPX interface.
Appendix C - Ethernet ODI Driver for OS/2 Installation The steps below outline a typical procedure for accessing the Novell NetWare Requester using the ODI interface running under OS/2: 1. 2. 3. 4. 5. Open a DOS window. Run AUTOSET . Set the IRQ=5, I/O port address=300, and select the adapter architecture. Save and exit AUTOSET . Install the OS/2 Workstation Service Requester (1 disk) and the OS/2 Utilities (2 disks) supplied with the Novell Network software.
EPC-33/34 Hardware Reference NDIS Driver for DOS Installation The NDIS ETHAT2 driver is used for 16-bit Western Digital mode and 16-bit NE2000 mode for the NDIS interface. It is used by various protocol stacks and applications, such as Windows for Workgroups (WFW). NDIS 3.0 protected mode support is already included in WFW. The steps below would be part of a typical setup for NDIS 2.0 real mode. C C 1. Set up PROTOCOL.INI according to the environment.
Appendix C - Ethernet terminal emulation) and FTPBIN (an FTP or File Transfer Program) that work with TCP/IP. In order to install the packet drivers, first run AUTOSET to initialize the adapter (IRQ, I/O port, shared memory base, etc.) Once AUTOSET has been run, install the packet driver.

Appendix F Flash Formatting Software This Appendix contains instructions for the use of Flash memory on the EPC-33/34. This software is used to format a resident Flash array (RFA) such as the one present on the EPC-33/34. Command line options for the device driver and syntax for the formatting command are included here for completeness.
EPC-33/34 Hardware Reference Before the Flash medium can be accessed by TrueFFS, it needs to be formatted. The TrueFFS format is essential for disk emulation capability. The details of this format are completely transparent to the user. TrueFFS medium is formatted with the TFORMAT utility (and not the DOS FORMAT command). The formatting required by TrueFFS is a one-time operation for each Flash medium, similar to the formatting of a floppy disk.
Appendix F - Flash Formatting Software Installation The TrueFFS standard installation requires the following actions: • Copy the RADSS.COM and TFFS.COM drivers and the TFORMAT utility to a directory on your fixed disk; and • Make changes in the BIOS Setups depending on whether your Flash module is to be a bootable image; and • Install the RADSS.COM and TFFS.COM drivers in your CONFIG.SYS file. RADSS.COM and TFFS.COM are DOS-installable device drivers, installed by the CONFIG.
EPC-33/34 Hardware Reference 5. Insert a blank floppy diskette in drive a: and format the floppy as a bootable system drive using the command FORMAT A: /s 6. Copy the TFORMAT utility to this new bootable diskette. 7. Reboot to the floppy. If you have any problems, make sure in your BIOS Setups the Boot Sequence menu is set for A: then C:. 8. From the A: prompt, type the following comand: TFORMAT C: /s:! 9.
Appendix F - Flash Formatting Software 6. Exit CONFIG.SYS and make sure that the path statement you entered for the device drivers is accurate. If not, create the appropriate directory and copy the files from the distribution disk into that directory. 7. Reboot. 8. Use the TFORMAT utility to format the Flash drive.
EPC-33/34 Hardware Reference The syntax of the TFORMAT command is: TFORMAT { drive-letter } [ /S:boot-image-file-name ] [ /S:drive-letter:] [ /S:! ] [ /S:* ] [ /BOOTSIZE:boot-image-size ] [ /USE:nnn ] [ /LOWMEM:size ] [ /LABEL:label ] [ /DOSVER:dos-major-version ] [ /SIZE:size ] [ /SPARE:n ] [ /Y ] Note F F An equal sign (=) may be used wherever a colon (:) is required. Examples: TFORMAT E: TFORMAT 2 /S:expbios.
Appendix F - Flash Formatting Software a different TrueFFS drive. The amount copied from the socket must be specified by the /BOOTSIZE parameter. The partition size will be the smallest that may contain the bootimage. This variation of the /S parameter is useful to create boot-images which are clones of another memory card. /S:! Do not create a boot-image partition. This option is necessary if, upon reformatting, an existing boot-image partition is to be deleted.
EPC-33/34 Hardware Reference Since the FAT and root directory reside in low sector numbers, this may improve performance. However, this option has an overhead in TrueFFS memory requirements. For more details, see Performance Considerations, later in this manual. The default is 64 KBytes. In principle, it is possible to specify a size that will span the entire medium, if the memory required to handle this is available.
Appendix F - Flash Formatting Software which it will become a read-only medium. TrueFFS will report that the medium is writeprotected when space for writing is exhausted. This option provides very limited functionality, and should not be used except in special cases. The option has the advantage of lowering the formatting overhead of TrueFFS, since a spare Flash erase zone is not needed for space reclamation. /Y Do not pause for confirmation before beginning to format.
EPC-33/34 Hardware Reference When SMARTDrive is installed, you should be aware of the following: • Because of the cache write-behind strategy, your data may still be in the process of being written several seconds after the writing application has terminated. In this case, your computer may respond sluggishly to commands for a while, because it is still busy with previous operations. • In case a write-fault occurs, SMARTDrive provides no option other than to retry the operation.
Appendix F - Flash Formatting Software Performance Issues TrueFFS performance in large part reflects the performance of the underlying Flash technology: reading from Flash chips is extremely fast. In comparison, Flash write (programming) and Flash erase are slow by one or two orders of magnitude. TrueFFS usually displays blazing fast read speeds, which are much faster than the customary speed of ordinary magnetic hard disks.
EPC-33/34 Hardware Reference UNKNOWN MEDIA or NON DOS FORMAT The Flash device you have accessed may not be properly formatted. If so, and you have previously formatted the card for Flash software other than TrueFFS, the device needs to be reformatted with the TFORMAT command to work with TrueFFS. It may be that some drivers installed on your computer use overlapping memory resources with TrueFFS, and hinder its access to the hardware. Check whether any other installed driver uses overlapping resources.
Appendix G Enabling the SRAM In order to enable the EPC-33/34’s SRAM, you must format the SRAM using SRAMFMT.EXE, then load the device driver SRAMDISK.SYS and reboot. SRAM Formatting Software SRAM data integrity may be jeopardized when power is removed during a series of write operations to the SRAM. For this reason, SRAMFMT checksums each sector. The SRAMDISK.SYS driver must compute the same checksum in order for the sector read to be successful.
EPC-33/34 Hardware Reference SRAM Disk Device Driver When installing an SRAM drive, make sure you run SRAMFMT on the drive before running the SRAMDISK.SYS driver. The driver will not recognize the SRAM disk until it has been formatted using SRAMFMT. The SRAM driver SRAMDISK.SYS allows use of the SRAM as a disk drive, usually E: after using an IDE disk for C: and flash as D:. The SRAM disk is not bootable. To load the SRAMDISK.SYS driver, edit the CONFIG.
