Microcode Update

Ê
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.

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.
