Something like this, I guess:
$ apt-cache show microcode.ctl Package: microcode.ctl [...] Description: Intel IA32 CPU Microcode Utility The microcode_ctl utility is a companion to the IA32 microcode driver written by Tigran Aivazian <tigran@veritas.com>. The utility has two uses: . a) it decodes and sends new microcode to the kernel driver to be uploaded to Intel IA32 family processors. (Pentium Pro, PII, Celeron, PIII, Xeon, Pentium 4 etc.) b) 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 re-flash your CPU permanently, reboot and it reverts back to the old microcode. The ideal place to load microcode is in BIOS, but most vendors never update it! . To enable microcode update, I need some kernel support, thus I need the linux kernel 2.2.18 or later, or 2.4.0 or later.
