Comment: | What is a Microcode Update? A system is working best when the configuration of all components is optimised. Therefore Intel has included a feature with the processors of the P6 family (starting with the Pentium Pro) that allows the command set (microcode) of the processor to be updated. That way, smaller bugs can be fixed and performance improvements installed without having to change the hardware. Reasons for Updating the Microcode To achieve best performance and ensure correct operation, microcode update with each BIOS update is recommended. Intel refers to running a processor without a microcode update as ”operating out of specification”. Processor Security on Fujitsu Siemens Computers Mainboards To protect the processor against operation with old or wrong microcode, Fujitsu Siemens Computers mainboards feature a function that interrupts the boot process if no matching microcode is available for the installed processor. An error message is displayed, saying ”Patch for installed CPU not loaded. Please run the bios flash update diskette”. The user has to confirm this by pressing F1. If the computer is nevertheless operated without a microcode update, error -free operation cannot be guaranteed. Other mainboard vendors do not care about a missing microcode. There is neither a hint nor an error message. Before a microcode update is released it has been tested and certified in the Fujitsu Siemens Computers labs. A signature is added that allows the BIOS to detect whether this update is approved for the installed processor. That way, only tested microcode updates that were developed especially for this processor are installed. This ensures that the processor is always operating with the latest and correct microcode. When should the Microcode be Updated? The microcode should be updated in the following situations: When you install a new processor When flashing the BIOS (usually performed automatically) The microcode should be updated after a BIOS Flash and prior to installing an operating system. Technical Background When updating the microcode, an update to the command set for the processor is loaded into a reserved area into the BIOS. With every boot, the BIOS loads the current microcode into the processor during the Power On Self Test (POST). If the BIOS fails to recognize the processor or cannot supply a matching microcode it displays an error message (”Patch for installed CPU not loaded. Please run the bios flash update diskette.”) that the user must confirm with the F1 key. In this case, the processor operates with the original command set. Performing the microcode update will detect the installed processor and load the corresponding microcode into the BIOS so that it will be available the next time the system boots. For space reasons, the BIOS c annot store the matching microcode for all processors. |
