| * Geode systems write protect the BIOS via RCONFs (cache settings similar |

| * |
| * This hard-coded location could have potential problems on SMP machines |
| * since it assumes cpu0, but it is safe on the Geode which is not SMP. |
| * |
| * Geode systems also write protect the NOR flash chip itself via MSR_NORF_CTL. |
| * To enable write to NOR Boot flash for the benefit of systems that have such |
| * a setup, raise MSR 0x51400018 WE_CS3 (write enable Boot Flash Chip Select). |
