P6 familly is concerned: PPro, PII, Celeron, PIII, Celeron2. Recent kernels have the ability to update this microcode. 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. This package contains microcode for Intel CPU, as well as microcode for AMD CPU (AMD Phenom(TM), AMD Opteron(TM) and AMD Turion(TM) 64 Ultra). %prep %setup -q -T -c %build %install rm -rf %{buildroot} mkdir -p %{buildroot}/lib/firmware/intel-ucode tar -xOf %{SOURCE0} | /sbin/intel-microcode2ucode - >/dev/null install -m 644 intel-ucode/* %{buildroot}/lib/firmware/intel-ucode tar xf %{SOURCE1} -C %{buildroot}/lib/firmware %clean %files %defattr(-,root,root,-) /lib/firmware/amd-ucode /lib/firmware/intel-ucode/
