  • Page 62: Memory Map

    Memory Map The module addresses memory using 24 address lines. This allows a maximum of 2 locations, or 16 Megabytes of memory. The table below shows how memory in the first megabyte is allocated in the system. First Megabyte Memory Map FFFFFH- BIOS in Flash EPROM F0000H...

  • Page 63: Input/Output Address Map

    Input/Output Address Map As with all standard PC/104 boards, the Input/Output (I/O) space is addressed by 10 address lines (SA0-SA9). This allows 2 or 1024 distinct I/O addresses. Any add-on modules you install must therefore use I/O addresses in the range 0-1024 (decimal) or 000-FFF (hex). If you add any PC/104 modules or other peripherals to the system you must ensure they do not use reserved addresses listed below, or malfunctions will occur.
  • Page 64 If the floppy and/or hard drive controllers are disabled, the I/O addresses listed will not be occu- pied. Only one of the I/O addresses shown for a Serial port is active at any time. You can use Setup to select which one is active or to disable it entirely. Only one of the I/O addresses shown for the Parallel printer port is active at any time.

  • Page 65: Hardware Interrupts

    Hardware Interrupts If you add any PC/104 modules or other peripherals to the system you must ensure they do not use interrupts needed by the cpuModule, or malfunctions will occur The cpuModule supports the standard PC interrupts listed below. Interrupts not in use by hardware on the cpuModule itself are listed as 'available'.

  • Page 66: The Bios

    The BIOS The BIOS (Basic Input/Output System) is software that interfaces hardware-specific features of the cpuModule to an operating system (OS). Physically, the BIOS software is stored in a Flash EPROM on the cpuModule. Functions of the BIOS are divided into two parts: The first part of the BIOS is known as POST (Power-On Self-Test) software, and it is active from the time power is applied until an OS boots (begins execution).

  • Page 67: Power On Self Tests (Posts)

    Power On Self Tests (POSTs) When you turn on system power, the BIOS performs a series of tests and initializations. Each test or initialization step is identified by a numeric "POST" code written to I/O address 378H. These codes can be displayed using a commercially available "POST code display board". The following table lists the POST codes expressed in hexadecimal, with their corresponding meanings.
  • Page 68 Errors While Booting If an error occurs while the system is booting and performing the Power On Self Tests, the system will respond in one of several ways. Its response depends on what type of error occurred and on cer- tain selections made in Setup.

  • Page 69: Default Configuration

    Default Configuration In addition to the Setup configuration stored on the board, the cpuModule has a permanent default configuration. The system will resort to using this default configuration in two situations: • An error occurs when accessing the EEPROM which holds the Setup on the module. •...
  • Page 70 Bypassing the Stored Configuration Under certain circumstances, you may want to bypass the configuration stored on the board. To do this: • Insert jumper JP5. This will force the cpuModule to boot using the default configu- ration. • Press the {Delete} key to enter Setup. You can then reconfigure the cpuModule correctly using Setup.

  • Page 71: Bios Routines For Hardware Control

    BIOS Routines for Hardware Control The cpuModule BIOS provides several routines which you may find useful to control hardware in your application programs. Because they control hardware which is specific to this cpuModule, these routines are also specific to this cpuModule. Routines are provided for: •...

  • Page 72: Eeprom Control

    EEPROM Control The cpuModule is equipped with an EEPROM, or "Electrically Erasable and Programmable Read Only Memory". This part is primarily used to store the configuration from the Setup program. You can also use this part for non-volatile storage of a small amount of data. Its contents are retained even with system power off and no backup battery connected.
  • Page 73 INPUTS: AH = 3 AL = word address (20H-3FH accepted) CX = number of words to read DS:SI = pointer to the buffer where the read values are stored RETURNS: AH = error code; if AH<>0, then AL = number of locations writ- Function 4 EEPROM verify.
  • Page 74 An example BASIC program illustrating EEPROM access is in the file CMV_EE.BAS on the cpu- Module utility disk.

  • Page 75: Watchdog Timer Control

    Watchdog Timer Control The cpuModule includes a Watchdog Timer, which provides protection against programs "hanging", or getting stuck in an execution loop where they cannot respond correctly. When enabled, the Watchdog Timer must be periodically reset by your application program. If it is not reset before the timeout period of 1.2 seconds expires, it will cause a reset of the cpuModule.

  • Page 76: Direct Hardware Control

    Direct Hardware Control Some of the cpuModule hardware is controlled directly without using BIOS routines. These include: • Real Time Clock Control • Parallel Port Control The following sections describe use of these features.
  • Page 77 Real Time Clock Control The cpuModule is equipped with a Real Time Clock (RTC) which provides system date and time functions, and also provides 64 non-volatile memory locations. The contents of these memory loca- tions are retained whenever an external backup battery is connected, whether or not system power is connected.
  • Page 78 Parallel Port Control The parallel port may be operated in SPP (output-only), ECP (extended capabilities), and bidirec- tional modes. The mode may be selected in Setup, or by application software. An example BASIC program illustrating control and access to the parallel port is in file CMx_PAR.BAS on the utility disk.
  • Page 79 Processor Clock Control The processor clock can be programmed in the setup program. Further, the processor clock may be changed by a solder jumper on the back of the board. For 586DX133 boards, the switch is between clock-quadrupled and clock-tripled operation. For 486DX100 boards, the switch is between clock- tripled and clock-doubled operation.

  • Page 80: Storing Applications On-Board

    Storing Applications On-board The cpuModule was designed to be used in embedded computing applications. In these applications, magnetic media like hard disks and floppy disks are not very desirable. It is better to eliminate mag- netic storage devices and place your operating system and application software into the cpuModule's Solid State Disk (SSD).
  • Page 81 Ways to Use the Solid State Disk Sockets There are two ways you may utilize the Solid State Disk sockets of the cpuModule. • Using devices which install as BIOS Extensions • Using Conventional SSD Memory BIOS Extension Devices such as Disk On Chip and PromDisk provide a relatively large amount of read/write disk space in one socket of the cpuModule.

  • Page 89: Using Virtual Devices

    Using Virtual Devices The cpuModule is designed for use in industrial environments as a stand-alone module, without ex- ternal peripherals. Nevertheless, it may be necessary to interface a cpuModule with I/O devices like a keyboard, monitor, or floppy or hard drive, especially for set-up or maintenance. The cpuModule is therefore provided with “Virtual Devices”, which allows you to access a key- board, monitor, and floppy disks without directly connecting them to the PC/104 bus of the module.
  • Page 90 Initiating Virtual Devices from Setup If the cpuModule is operational, Virtual Device mode can be accessed from Setup. This method has the advantage that you can individually select devices for use in Virtual Devices mode. To use this method, run Setup on the cpuModule and select the Virtual Devices you wish to use. The settings for floppy drive A:, keyboard, and video state, and hard disk C: can each be set to "serial".
  • Page 91 Initiating Virtual Devices by Jumpering Serial Port Pins Virtual Device mode can also be initiated by shorting two pins on the first or second serial port con- nector of the cpuModule. This method has a slight disadvantage in that the keyboard, video, and floppy and hard drives are all redirected to the serial port.
  • Page 92 Disconnecting the Host Computer To disconnect the host computer, press the {Prt Scrn} key at any time. The host computer will re- cover its peripherals and returns to normal operation.
