    1.3. Overview 1.3.1. Technical Details The EUROCOM 300 is an Intel Pentium M single-board computer with PCISA (PISA) interface, optimized for real-time applications, while maintaining full PC compatibility. This is the ideal platform for industrial applications with real-time operating systems, extending ELTEC's successful BAB product line for Intel CPUs.

  • Page 13: Boot Prom

    The board can drive PCI buses (passive back planes) with up to 4 peripheral slots, all of them can obtain bus mastership (DMA). 1.3.1.9. Timer The EUROCOM 300 has three standard PC programmable timers for timing interrupts in the 1 us to 1000 ms range. 1.3.1.10. Non-volatile Memory Besides the normal RTC-based non-volatile memory, an additional user memory is present (optional).

  • Page 19: Power On Self Test

    1.5.1. Power On Self Test When the EUROCOM 300 is powered on, the BIOS tests and initializes the hardware and programs the chipset and other peripheral components. During this time, Power On Self Test (POST) progress codes are written by the system BIOS to I/O port 80h, allowing the user to monitor the progress with a special monitor.

    Figure 1.5: The graphical POST provides an instant-on and controlled display for the user to view. When the EUROCOM 300 is powered on for the first time, you’ll need to configure the system through the Setup Screen System (described later) before peripherals, such as disk drives, are recognized by the BIOS. The information is written to battery-backed CMOS RAM on the board’s Real Time Clock.

  • Page 57: Interrupts

    300 4.4. Interrupts The EUROCOM 300 uses the PC interrupts for different purposes. First there are the PC compatible interrupt sources like serial, parallel I/O, timer, keyboard, EIDE, real-time clock, PS/2 mouse and coprocessor. These interrupt sources require dedicated interrupt numbers, which are fixed. Never use these interrupt numbers for other modules.
