The utility has two uses: + +* It decodes and sends new microcode to the kernel driver to be uploaded + to Intel IA32 processors. (Pentium Pro, PII, PIII, Pentium 4, Celeron, + Xeon etc - all P6 and above, which does NOT include pentium classics). + It also supports processors of the x86_64 architecture. +* It signals the kernel driver to release any buffers it may hold. + +The microcode update is volatile and needs to be uploaded on each system +boot i.e. it doesn't reflash your cpu permanently, reboot and it reverts +back to the old microcode. + +To use this utility you need to compile the kernel driver (found under +"Processor type and features"). The microcode itself can be found at +http://downloadcenter.intel.com/default.aspx and should be placed under +/etc/microcode.dat You probably want to have your microcode updated +each time the system boots, then call "/usr/sbin/microcode_ctl -u" from +/etc/rc.d/rc.local |
