Main Memory
The CC3-CAJUN is equipped with a socket for installing a single 144-pin SO-DIMM module.
Minimum common memory size is 128MB; maximum memory size is 512MB. Due to the video
requirements of the i815 chipset, the recommended minimum memory for the Windows 2000
and Windows XP operating systems is 256MB (some of the system memory is dedicated to the
graphics controller). The supported on-board memory is entirely chacheable. The memory
module is a unbuffered SD-RAM, PC133 style. The contents of the SPD Eeprom are displayed on
system start by the BIOS. The memory clock is 133MHz maximum, due to limitations of the
815GMCH (Graphics and Memory Controller Hub).
The GMCH is sometimes also referenced as 'Northbridge'. No special drivers are needed for the
memory controller portion of the GMCH - configuration is done by the BIOS (including the
Video BIOS) and the operating system.
LAN Subsystem
The CC3-CAJUN is equipped with the 82551ER 100Mbps Ethernet controller. Features include:
C PCI bus mastering 32-bit, 33MHz
C 100Base-TX (Fast Ethernet, half- or full-duplex) and 10Base-T (Classic Ethernet) capability
using a single RJ45 connector
C IEEE 802.3µ Auto-Negotiation for the fastest available connection
C Jumperless configuration (complete software-configurable)
Two display LEDs integrated into the RJ-45 connector signal the LAN connection speed and the
LAN link and activity status.
The NIC (Networking Interface Controller) resides on the local PCI bus. Its MAC address (unique
hardware number, mostly represented by 12 hexadecimal characters) is stored in an EEPROM.
A label may be present on the board showing its MAC ID
1
. You could also execute "ifconfig"
(Linux) or "ipconfig /all" (Windows) in order to call up the MAC ID.
The Intel Ethernet software and drivers for the 82551ER are available from Intel's World Wide
Web site for download.

EKF native MAC IDs start with 00:C0:88. A label, if present, may show the full physical address
as 2-D barcode (DataMatrix), and in addition the least 6 hex characters as human readable
letters.
