Microcode Update
What is a microcode update?
As there are no drivers for processors, Intel offers the possibility from the P6 family (Pentium Pro)
on to update the command set (microcode) of the processor. 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.
