Microcode Update

Note the signals issued from the loudspeaker. You have successfully restored the BIOS if you

hear the signal sequence "short-short—long—long—long" and the diskette access indicator is

dark. This can take a few minutes.

Open the casing as described in the operating manual.

Set the switch for "Restore system BIOS" to OFF.

Close the casing as described in the operating manual.

Remove the floppy disk from the drive.

Start the PC and invoke BIOS Setup.

Select the menu item Reset Configuration in the menu Advanced and change the setting to Yes.

Save the change and terminate BIOS Setup.

The BIOS recovery has now been completed. The system restarts.

Detailed information on the BIOS recovery is contained in the manual "BIOS Setup"

("Drivers & Utilities" CD).

Microcode Update

What is a microcode update?

Da es für Prozessoren keine Treiber gibt , bietet Intel ab den Prozessoren der P6-Familie (Pentium

Pro) die Möglichkeit, den Befehlssatz (Microcode) des Prozessors zu aktualisieren. This enables

minor errors to be corrected and the performance to be increased.

To guarantee the best possible performance and error-free operation, Intel recommends updating

the microcode regularly. Intel refers to the use of the processor without regular microcode updates

as operation outside the specifications.

Safety for processor on Fujitsu Siemens Computers mainboards

If the processor uses an old or incorrect microcode, error-free operation cannot be ensured. Fujitsu

Siemens Computers has therefore implemented a function on its mainboards that interrupts the

booting process if no suitable microcode is available for the installed processor. The output error

message is

Patch for installed CPU not loaded. Please run the bios flash update

diskette.

This message appears until the microcode update has been carried out. If the computer is

nevertheless operated without a microcode update, error-free operation is not ensured.

When should a microcode update be carried out?

A microcode update should be carried out in the following cases:

Following installation of a new processor

When a new microcode update is issued.

In contrast to the BIOS update, only an updated version of the processor command set is stored.

The system BIOS remains unaffected by this.
