Chapter 4 The Set-up Program This chapter explains how to use and modify the setup options. These options allow configuring properly the CPU board. Note. The Setup Program can be improved to match the technical requirements. To enter in the Setup Program reboot or switch-on your module and then press the “F2” key. After waiting a few seconds the main menu will appear. The Main menu of the set-up program shows a list of options that are available.
PC/104-Plus – CPU-1461 Module Use the cursor arrow keys to move the highlight to other options. When an option (i.e.: General) is highlighted, it is possible to execute it by pressing the “Enter” key. A table of items will be displayed on the right side of the screen. Now it is possible to select among several items (i.e.: Time, Date, Floppy Disk 1,… ) using the arrow keys and the “Enter” key. When an item is highlighted, it is possible to change its value by pressing the “PageUp” and “PageDown” keys.
PC/104-Plus – CPU-1461 Module 29 The follow screen will be displayed: Select with the “ENTER” key the first option “Save data to Flash” to store the parameters into the EEPROM. Select Discard changes to leave unaltered the previous stored parameters.
PC/104-Plus – CPU-1461 Module The Set-up pages The Set-up Program is composed of several pages.
PC/104-Plus – CPU-1461 Module 31 Time The time is displayed in standard format: hh mm ss (hours - minutes - seconds). Date The date is display in standard format: MMM DD YYYY (month - day - year). Floppy disks The floppy disks are numbered starting from one and the BIOS maps these drivers starting form the letter “A”. Note: when the boot sequence starts from floppy disk number one (DOS letter “A”), any device selected as floppy disk 1 can be a bootable disk.
PC/104-Plus – CPU-1461 Module Boot Try Sequence The Boot Try Sequence allows exchanging the boot disk order among Floppy Disk 1, Hard Disk 1, CD-ROM and NET.
PC/104-Plus – CPU-1461 Module 33 Primary and secondary EIDE This option enables or disables the on-board EIDE hard disk controllers. For example, if an external hard disk controller needs to be used, the internal one must be disabled.
PC/104-Plus – CPU-1461 Module Communications Page This page concerns all the on-board communication interfaces: Serial Port1 • Mode • VP2000 and VT100 Serial Port2 • Mode • VP2000 and VT100 Parallel Port • Mode • VP2000 and VT100 Serial Ports 1 and 2 Serial Port 1 is RS232 only. Serial Port 2 is RS232/422/485.
PC/104-Plus – CPU-1461 Module 35 • Note: not all consecutive IRQ numbers from 3 to 15 can be used; to help the selection, the Setup program displays legal IRQ numbers only. • Note: the IRQ is shared: the ports can use the same IRQ number. VP2000 and VT100 With this option the user can enable or disable the VP2000 and VT100 functionality serial ports.
PC/104-Plus – CPU-1461 Module Primary and Secondary ATAPI Page This option concerns mass storage devices using a standard EIDE interface. The CPU board has two EIDE controllers, so the ATAPI Units can be separated in two parts: ATAPI Primary and ATAPI Secondary. In any case the options are the same. • Note: ATAPI (or EIDE) devices can be both hard disks and CD_ROM devices or, sometimes, storage tape-units. • Note: each EIDE interface supports two peripherals, called master unit and slave unit.
PC/104-Plus – CPU-1461 Module 37 PIO Mode PIO is a special data-transfer system between two or more EIDE devices, where all the data pass through the processor. There are five transfer rates, called PIO mode n (with n=0..4). If the Auto (autodetect) option is disabled, the PIO mode must be specified. Option PIO-0 PIO-1 PIO-2 PIO-3 PIO-4 Description Transfer Rate of 3.3 MBps Transfer Rate of 5.2 MBps Transfer Rate of 8.3 MBps Transfer Rate of 11.1 MBps Transfer Rate of 16.
PC/104-Plus – CPU-1461 Module Detect Now Using the Detect Now option, the user can start manually the hard-disk autodetect procedure and see immediately the result, as well as the size (in Mbytes), in terms of cylinders, heads and sectors numbers. Advanced page This page allow the configuration of: • Legacy PnP Support • Watch Dog start at boot • Watch Dog Timeout Legacy PnP Support can be enabled or disabled.
PC/104-Plus – CPU-1461 Module 39 PCI Advanced Page This page can be used to specify some advanced PCI options like: ISA IRQ Latency Time (both for CPU and devices) ISA IRQ This option makes possible any assignment between an ISA IRQ (for the Interrupt Controller) and the four PCI IRQ lines A, B, C and D. Obviously not all the assignments are legal, but the Setup programs shows only the available ISA interrupts.
PC/104-Plus – CPU-1461 Module ISA Bus This page allows configuring for the I/O spaces and the memory address windows: Error Handling Page Generally, in a normal desktop BIOS, when an error is encountered by the POST sequence, the bootstrap stops and waits for a reboot. For example, a simple keyboard absence represents an irrecoverable error. This can be a serious problem in embedded systems.
PC/104-Plus – CPU-1461 Module 41 Error on Keyboard The user can decide for himself if a keyboard error must stop the boot process or not. Option Ignore Prompt User Description The keyboard error is ignored When a keyboard error occurs, the system stops and waits for the user Note Error on Video The user can decide for himself if a video error must stop the boot process or not.
Chapter 5 Watch Dog Timer This chapter explains how to use the Watch Dog timer. You can also find information about how to use it through the System BIOS or directly by I/O mapped registers.
PC/104-Plus – CPU-1461 Module What is a Watch Dog? The Watch Dog is a hardware countdown timer (2-255 sec./min.) that can be used to automatically restart the system in case of system or program execution failure. Once enabled the Watch Dog must be refreshed (reloaded with the starting timeout value) by the application software before the timeout expires. If the program execution stops, the application software will not refresh the Watch Dog anymore.
PC/104-Plus – CPU-1461 Module 45 How to turn the Watch Dog OFF Make a call to INT52h with AH=00Dh. The Watch Dog will be disabled. Then the Watch Dog doesn’t need to be periodically refreshed anymore. Assembler code example: MOV INT AH,00Dh 052h Directly accessing Watch Dog I/O mapped registers This method must be used when the operating system you are using doesn’t allow you to use the System BIOS calls, or when you need a different timeout than 2 seconds.
