WARNING ! This equipment generates and can radiate radio frequencies.
If not installed in accordance with the instruction manual, it may cause
interference to radio communications. The equipment has not been tested for
compliance with the limits for class A computing devices, pursuant to subpart
J of part 15 of FCC rules, which are designed to provide reasonable protection
against such interference, but temporary usage is permitted as per
regulations. Operation of this equipment in a residential area is likely to cause
interference, in which case the user, at his own expense is required to take
whatever measures may be required to shield the interference.

1.2 Overview
1.2.1 Technical Details
The EUROCOM®238 is a Celeron or Pentium III -based single
board computer with a CompactPCI interface. The standardized
Eurocard format permits setting up multiprocessor systems in proven
19" racks. This is the ideal platform for industrial/telecom
applications.
The board is based on the Intel 440BX PCI chip set, the reference for
Pentium III and Celeron chip sets. Also, availability for longer
periods than what is common in the PC market is guaranteed.
1.2.1.1 CPU
Socket 370 processors are supported: Celeron at 566 MHz for
performance comparable to Pentium II processors or Pentium III at
850 MHz. The CPU has FPU, MMU and first as well as second level
cache. The CPU performance index is 32.7 SPECint95 and 26.5
SPECfp95 for the 850 MHz Pentium III.
Table 1—1: Supported CPUs
CPU Celeron Pentium III
L1 Cache 16 kB 32 kB
L2 cache 128 kB 256 kB
Bus Speed 66 MHz 100 MHz
1.2.1.2 Memory Configuration
The 64-bit wide memory allows configurations of 128 MBytes with
on-board 100-MHz SDRAMs. The second-level cache, located on
the CPU chip, runs with the full CPU clock.

1.2.1.3 Firmware
The BIOS is stored in a Boot-Block Flash-EPROM which enables
easy BIOS updates. Boot from floppy, EIDE, SCSI, CD-ROM, LS-
120 is supported. A net boot EPROM can be added on request.
1.2.1.4 Graphics Interface
The graphics interface of the EUROCOM®238 is the AGP-based
controller C&T 69030. It achieves superior performance through the
separate 32-bit interface to the AGP bus and 4 MB on-chip frame
buffer memory. CRT monitors and flat panel displays are supported
by routing TTL output signals of the graphics controller to the
transition board as well as analog outputs to the front panel.
Table 1—2: Maximum Resolution and Refresh Rates
Display Mode Resolution Bit / Pixel Rate [Hz]
CRT 1600 x 1200 8 60
CRT 1280 x 1024 16 75
CRT 1024 x 768 24 85
CRT + flat 1024 x 768 8 85 + 60
CRT + flat 800 x 600 24 60 + 60
The table shows maximum resolutions and refresh rates for analog
video (CRT) and simultaneous displays on CRTs and TFT flat panels
(same data and different timing). Different data displayed is possible,
although.
1.2.1.5 Floppy Disk
All types of common 3,5" and 5,25" Floppy drives are supported.
1.2.1.6 Hard Disks
Hard Disks are supported either by the PCI-based IDE port with
Ultra DMA/33 transfer or the Ultra-wide SCSI port with 40 MB/sec
transfer rate. SCSI and secondary IDE are routed to the transition
board.

1.2.1.7 Ethernet Interface
The network interface uses the network controller Intel 82559 for
10/100 Mb connectivity with 10BaseT (twisted pair) or 100Base TX
connectivity.
1.2.1.8 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; one of these channels is routed to the front panel. Printers
can be connected to a fully bidirectional parallel port supporting
IEEE 1284 enhanced modes (EPP and ECP). PS/2-compatible
keyboard and mouse interface are provided. One USB port is
supported at the front panel and one on the transition module. Beeper
output is also routed to the transition board.
1.2.1.9 CompactPCI Interface
The CompactPCI interface is implemented with the Intel 21154 64-
bit bridge chip, delivering system slot capabilities for 32-bit and 64-
bit cPCI systems. It features transfer rates of up to 128 MByte/s
between board-internal resources and CompactPCI devices or 256
MB/s between two external devices.

1.2.1.10 CE Conformity
All I/O-signals routed to the front panel are filtered by special EMC
filters to meet EMC requirements (class B).
1.2.1.11 Watchdog
The EUROCOM®238 has an on-board watch-dog for operator-less
environments.
1.2.1.12 PMC
A PCI extension card for PMC boards is provided. A PMC module
carrier board (PMCC) can be installed to provide three PMC module
slots. The PMC connectors are buffered with an additional 32-bit
PCI-PCI bridge device, located on the carrier board. Additionally,
the carrier board acts as a system controller for a second cPCI
segment of up to 7 slots, located in the right half of the cPCI rack.
This segment, in turn, is connected to the base board with an
additional 64-bit PCI-PCI bridge allowing 64-bit data transfers
between the two cPCI segments.
PMC I/O is routed to the backplane P3..5 connectors, according to
the cPCI standard.
1.2.1.13 IDE Hard Disk
An IDE hard disk (2.5", max. 9.5 mm height for single-slot usage)
can be mounted on the EUROCOM®238, connecting to primary
IDE with a short 1:1 cable. This allows building a compact system
without extended cabling for external SCSI or IDE devices.
Simultaneous IDE and SCSI operation is possible.
