1.1.3. Overview
1.1.3.1. Technical Details
The EUROCOM 258 is an Intel Pentium M single-board computer with a CompactPCI 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.
Chapter 1. Hardware part

1.1.3.1.1. CPU
The CPU has FPU, MMU and second level cache. Host bus speed is 400 MHz for Pentium M 1,6 GHz.
The standard version of the EUROCOM 258 has a 1,6 GHz Pentium M, mounted with socket The board
is based on the Intel 855 PCI chip set, following Intel's design guidelines. As it is part of the “embedded
product line”, availability for longer periods than what is common in the PC market is guaranteed.
The board is based on the Intel 815 PCI chip set, following Intel’s “Universal Motherboard” design
guidelines. As it is part of the “embedded product line”, availability for longer periods than what is
common in the PC market is guaranteed.
1.1.3.1.2. Memory Configuration
The 64-bit wide memory allows configurations from 256 MBytes to 1024 MBytes using one SO-DIMM with
166 MHz DDR-RAMs. The memory size is detected automatically. The second level cache, located on
the Banias chip, runs with the full CPU clock. There is a nonvolatile memory with 2 kBytes capacity on the
board.
1.1.3.1.3. Firmware
The BIOS (General Software) is stored in a Boot-Block structured Flash-EPROM which enables easy
BIOS updates. Boot from floppy, IDE hard disk, CD-ROM, CompactFlash is supported. A net boot is
supplied in the same Flash-EPROM.
1.1.3.1.4. Graphics Interface
The graphics interface of the EUROCOM 258 is the graphics controller of the 855 chip set. It can display
up to 1600 x 1200 pixels in true color (24 bpp) at 85 Hz. Since it uses an unified memory graphics frame
buffer, there is a trade-off between the bandwidth used for display and for CPU access. The table gives
an idea of the bandwidth reserved for graphics:
Display Video bandwidth Bus load (relative to total
approx. bandwidth @ 333
MHz)
1024 * 768 (16 bpp, 85 Hz) 130 MB/s < 5%
1280 * 1024 (24 bpp, 85 Hz) 330 MB/s < 12.5%
1600 * 1200 (24 bpp, 85 Hz) 490 MB/s 20%
The graphics interface is fully compatible with the VGA standard at the hardware, register and BIOS level.
Mode Initialization is supported at the BIOS and register levels ensuring compatibility with all application
software.

1.1.3.1.5. Hard Disks / Mass Storage
Hard Disks are supported by the PCI-based EIDE port with Ultra DMA/100 transfer. Secondary IDE is
routed to the P5 connector. Primary IDE is routed to an on-board connector, allowing for an on-board
2.5# disk (mounted as an alternative to PMC modules) with up to 9.5 mm height. A Compact Flash
connector is supplied on-board for alternative or simultaneous onboard use. All types of common 3,5"
Floppy drives are supported.
1.1.3.1.6. Ethernet Interfaces
The network interface on the EUROCOM 258 use the network controller i82559ER for 10/100 Mb
connectivity with the 10BaseT or 100BaseTX standards. Optionally, port can be ordered with 1 Gb
capability (i8254). Remote boot from LAN is supported. Furthermore you can order E258 with two network
interfaces ( 10/100/1000Tx standard) Please contact ELTEC about this issue
1.1.3.1.7. I/O Features
Two asynchronous 16550-compatible serial channels with up to 115 kbaud transfer rate and 16-byte
FIFO with RS232 levels are available. PS/2-compatible keyboard and mouse are provided, as well as four
USB ports 2.0 , one routed to the front panel.
1.1.3.1.8. Universal CompactPCI Interface
The CompactPCI interface is implemented with the Hint HB6 universal bridge chip. It features FIFOs for
fast transfers. This bridge is a universal (transparent or non-transparent) bridge, intended for use in
system as well as peripheral slots. The standard version of the EUROCOM 258 has a transparent-only
bridge, however. The use of atomic cycles through the CompactPCI interface cannot be guaranteed. A
Power Fail signal on the CompactPCI can generate an interrupt for the EUROCOM 258 CPU.
1.1.3.1.9. Watchdog / Timers
The EUROCOM 258 has an on-board watchdog for automatic reboot after software failures. The timer
has programmable two 16-bit counters, clocked with 2 MHz.

1.2. Installation
1.2.1. Introduction
Do always observe precautions for handling electrostatic devices when unplugging boards from the rack
or otherwise handling boards.
Avoid touching integrated circuits except in an electrostatic free enviroment. Electrostatic discharge can
damage circuits or shorten their liftime.
• Carefully remove the board from the shipping carton.
• Save the original shipping container and packing material for storing or reshipping the board.
• Inspect the board for any shipping damage. If undamaged, the board can be prepared for system
installation.
1.2.2. SO-DIMM Installation
If the EUROCOM 258 is not shipped with DRAM SO-DIMMs, the user must insert his own SO-DIMMs on
the board. The EUROCOM 258 is not able to run without DRAM.
SO-DIMM installation can be done easily. The board has one SO-DIMM socket, X201. The BIOS software
detects automatically if the bank is populated. Also the size of the DIMMs is detected automatically.
The SO-DIMM is simply plugged into the socket (it fits only in one orientation). The two metal latches on
the socket must hold the SODIMM. Otherwise the SO-DIMM is not properly connected.
1.2.3. Board Installation
All add-on modules on the EUROCOM 258 are already installed when shipped. There is no reason to
remove add-on modules.
The EUROCOM 258 requires the front panel space of one CompactPCI slot. After the board was plugged
into the CompactPCI backplane connectors the screws on the front panel can be fixed with the rack.
Make sure that the power supply within the rack meets the power requirements specified in Section
"Power Requirements". Also the operating requirements must meet the values specified in Section
"Environmental Conditions".
Caution:
Due to the low power consumption during power up, the board is not able to comply with the minimal
power consumption for an ATX Power Supply former then Version V1.2 (less than 1A on +5V Power
Rail). Therefore it is important to have additional load (like Harddisk or Floppy) to fullfil this condition when
using an ATX (Power Supply).
1.2.3.1. Graphics
If a CRT monitor is used, a standard VGA cable (15 pins) is connected between the monitor and
connector X806 of the board. Make sure that your monitor is capable of displaying higher video
resolutions. If a video mode generates horizontal frequencies much higher than the maximum value of
your monitor, the monitor may be destroyed! If your monitor is not able to display a mode, switch off or
disconnect the monitor in advance and select an appropriate video mode for the monitor.
Chapter 1. Hardware part
7

1.2.3.2. Keyboard
A standard PS/2 keyboard can be connected to X804. If an AT keyboard is desired, cable adapter
ADAP-210 can be used. A PS/2 keyboard can be connected directly.
1.2.3.3. Mouse
A standard PS/2 mouse can be connected to X804 using a splitadaptor.
1.2.3.4. Serial
A serial device can be connected directly to X803. The interface supports speed up to 115200 kb/s.
1.2.3.5. Ethernet
A Network can be connect using 10BaseT, 100BaseTX or 1000BaseT standard. It can be connected to
X1001.
1.2.3.6. CompactFlash
A CompactFlash-Card Typ 1 can be installed in the socket X501. The card is mapped as an IDE-Drive
into the system. It will be the Master device of the primary IDE-Channel.
Chapter 1. Hardware part
8

1.2.3.7. OnBoard Harddisk
An 2.5" IDE Harddisk can be connected to X611. The maximal height is limited to 9.5 mm to meet the
requirements of an one slot CompactPCI-Board. The harddisk is connected to the same IDE-Channel as
the CompactFlash. This makes it important to jumper the harddisk as slave, if there is an
CompactFlash-Card installed or as master if there is no CompactFlash installed.
1.2.3.8. LEDs and Resetswitch
Figure 1.2. Location LEDs and Resetswitch
There are two UserLEDs, one LED for Harddisk-activity and one for CPU-activity. The last one also
signals the case of overtemperature. This makes the CPU throttle with normally 25% Speed. In the event
of catastrophic thermal overload the CPU shutdown the system imediatly and both Ethernet Status LEDs
will blink yellow (see Table 1.3 / 1.4). The switch resets the whole CPU and the CompactPCI-Rack.

1.2.4. BIOS Setup
The EUROCOM 258 is delivered with an EMBEDDED BIOS from GENERAL SOFTWARE. The BIOS
includes a setup menu to configure basic settings. ELTEC ships the EUROCOM 258 with optimized BIOS
settings. If desired, most of the BIOS settings can be changed (some settings are hardwired). Also if the
battery for the CMOS RAM is weak, the RAM may loose its contents making a new setting of the setup
necessary. Caution should be taken because some changes of settings may cause an erroneous system
behavior.
If the EUROCOM 258 is used as a cPCI Peripheral Board the type and size of memory it occupies in the
cPCI address space needs to be set in the Custom Configuration section of the BIOS setup. These
values are needed by the System Board to initialize the System. The translation address may also be set
in the BIOS but can be changed by the application later.
It may happen that the values in the nonvolatile memory inhibit starting of the EUROCOM 258. In this
case the RUN LED will light for a short time when the board is reset and then stays dark. The board can
be reset to the default values by the following procedure:
• remove the board from the rack
Chapter 1. Hardware part
10

• momentary shortcut the two pads marked in Figure 1.4 Location of Clear CMOS Jumper
• reinstall board
Figure 1.4. Location of Clear CMOS Jumper
1.2.5. Cooling Requirements
Cooling of the EUROCOM 258 and especially of the processor is essential. Depending on the processor
frequency and the type of heatsink used different maximum air temperatures can be tolerated. See
Section 'Environmental Conditions' for a detailed list of specified air temperatures.

1.2.6. Testing the Installation
After power is switched on the BIOS displays a message on the CRT screen. It takes some time before
the BIOS is ready to display. After system boot from harddisk or floppy drive the keyboard should work.
The driver software for the mouse should detect the mouse device. If a network is installed, other network
devices (if existent) should be accessible (e.g from Windows file manager). These default configurations
may be different depending on the required CPU frequency.
