The equipment and tools you use must be free of static charge. - Remove the power plug from the mains supply before inserting or removing boards.
Always hold boards by their edges. - Never touch connector pins or conductors on the board.
An overview of the features is provided in the data sheet.

Installing/removing the processor

Disconnect the system from the mains voltage before performing any of the tasks described below. Details are contained in the operating manual of your system.
Technical data
- Socket LGA 775, max. 65W; Intel® Core 2 DUO Processors 1333/1066/800 MHz FSB; Intel® Pentium Dual Core E2xxx Processors 800 MHz FSB, Intel® Celeron® Processors 4xx 800 MHz FSB
- A current list of the processors supported by this mainboard is available on the Internet at: "www.fujitsu-siemens.com/mainboards".

Never touch the underside of the processor. Even minor soiling such as grease from the skin can impair the processor's operation or destroy the processor. Place the processor in the socket with extreme care, as the spring contacts of the socket are very delicate and must not be bent.
If one or more spring contacts are bent, on no account insert the processor as it may be damaged by doing so. Please contact the responsible vendor.
Procedure

The processor socket is covered with a protective cap to protect the spring contacts. In the event of a warranty claim, the mainboard can only be taken back by Fujitsu Siemens Computers with the protective cap secured!

Remove the heat sink.
Press down the lever and unhook it.
Fold up the frame.
Hold the processor between your thumb and index finger and insert it into the socket (b) so that the marking of the processor is aligned with the marking on the socket (a).
Press the lever downward until it is hooked in again.
Remove the protective cap and keep it.

Please note that, depending on the heat sink used, different heat sink mounts are required on the mainboard.
Depending on the configuration variant, you must pull a protective foil off the heat sink or coat the heat sink with heat conducting paste before fitting it.
- Secure the heat sink - depending on the model - with four screws or push it into the mounts.
Installing/removing main memory
Technical data
| Technology | DDR2 667 / 800 unbuffered DIMM modules 240-Pin; 1.8V; 64 Bit, no ECC |
| Total size | 128 MByte to 8 GByte |
| Module size | 128, 256, 512, 1024 or 2048 MByte for one socket |
A current list of the memory modules recommended for this mainboard is available on the Internet at: "www.fujitsu-siemens.com/mainboards".
At least one memory module must be installed. Memory modules with different memory capacities can be combined.

You may use only unbuffered 1.8V memory modules without ECC.
DDR2-memory modules must meet the PC2-5300U or PC2-6400U specification.

If you use more than one memory module, make sure to distribute the memory modules over both memory channels. By doing this you use the performance advantages of the dual-channel mode.
System performance is maximised when the same memory size is used in Channel A and Channel B.
To simplify equipping, the slots are colour coded.
With a memory configuration of 8 Gbytes the visible and usable main memory can be reduced down to 7 Gbytes (depending on the system configuration).

| Number of memory modules inserted | ||||
| Slot to be used | 1 | 2 | 3 | 4 |
| Channel A, Slot 1 | X | X | X | X |
| Channel B, Slot 2 | X | X | X | |
| Channel A, Slot 3 | X | X | ||
| Channel B, Slot 4 | X | |||
The installation/removal is described in the "Basic information on mainboard" manual.
PCI bus interrupts - Selecting correct PCI slot
Extensive information on this section is contained in the manual "Basic information on mainboard".

To achieve optimum stability, performance and compatibility, avoid the multiple use of ISA IRQs or PCI IRQ Lines (IRQ sharing). Should IRQ sharing be unavoidable, then all involved devices and their drivers must support IRQ sharing.
Which ISA IRQs are assigned to the PCI IRQ Lines is normally automatically specified by the BIOS (see "BIOS Setup" description).
Monofunctional expansion cards
PCI/PCI Express expansion cards require a maximum of one interrupt, which is called the PCI interrupt INT A. Expansion cards that do not require an interrupt can be installed in any desired slot.
Multifunctional expansion cards or expansion cards with integrated PCI-PCI bridge
These expansion cards require up to four PCI interrupts: INT A, INT B, INT C, INT D. How many and which of these interrupts are used is specified in the documentation provided with the card.
The assignment of the PCI interrupts to the IRQ Lines is shown in the following table:
On board controller
| PCI INT LINE | 1 (A) | 2 (B) | 3 (C) | 4 (D) | 5 (E) | 6 (F) | 7 (G) | 8 (H) |

| PCIe X1 | - | - | - | - | - | - | x | - |
Use first PCI/PCI Express slots that have a single PCI IRQ Line (no IRQ sharing). If you must use another PCI/PCI Express slot with IRQ sharing, check whether the expansion card properly supports IRQ sharing with the other devices on this PCI IRQ Line. The drivers of all cards and components on this PCI IRQ Line must also support IRQ sharing.
BIOS Update
When should a BIOS update be carried out?
Fujitsu Siemens Computers makes new BIOS versions available to ensure compatibility with new operating systems, new software or new hardware. In addition, new BIOS functions can also be integrated.
A BIOS update should also always be carried out when a problem exists that cannot be solved with new drivers or new software.
Where can I obtain BIOS updates?
The BIOS updates are available on the Internet at "www.fujitsu-siemens.com/mainboards".
BIOS update under DOS with bootable BIOSupdate floppy disk - brief description
Download the update file from our website to your PC.
Insert an empty floppy disk (1.44 Mbyte).
Run the update file (e.g. 2461103.EXE).
A bootable update floppy disk is created. Leave this floppy disk in the drive.
Restart the PC.
Follow the instructions on screen.

Detailed information on the BIOS update under DOS is provided in the "BIOS Setup" manual ("Drivers & Utilities" CD).
BIOS update under Windows with DeskFlash utility
A BIOS update can also be carried out directly under Windows with the DeskFlash utility. DeskFlash can be found on the "Drivers & Utilities" CD (under DeskUpdate).
