%description |
| 18 |
Since PentiumPro, Intel CPU are made of a RISC chip and of a microcode whose |
| 19 |
purpose is to decompose "old" ia32 instruction into new risc ones. |
| 20 |
P6 familly is concerned: PPro, PII, Celeron, PIII, Celeron2. |
| 21 |
Recent kernels have the ability to update this microcode. |
| 22 |
|
| 23 |
The microcode update is volatile and needs to be uploaded on each system |
| 24 |
boot. I.e. it doesn't reflash your cpu permanently. |
| 25 |
Reboot and it reverts back to the old microcode. |
| 26 |
|
| 27 |
This package contains microcode for Intel CPU, as well as microcode for |
| 28 |
AMD CPU (AMD Phenom(TM), AMD Opteron(TM) and AMD Turion(TM) 64 Ultra). |
