Core 2 Duo Support Requires BIOS Update

Contrary to rumors and claims, a BIOS update will be needed for many laptops to support Core 2 Duo.
Laptop enthusiasts looking to upgrade their Yonah-based laptops to the upcoming Merom processors are not in luck.
Contrary to rumors and claims, a BIOS update will be needed for many laptops to support Core 2 Duo, also known under the code-name Merom. Many Calistoga-based machines, such as the Fujistu N series and the Apple Mac Mini, support Merom without a BIOS update.
However, this will not always be the case. Laptop Logic has discovered that the Asus S96J, also known as the Z96J, does not support Merom. When we inserted a Merom processor into our Asus S96J testbed, the laptop reported that the CPU microcode was unknown and refused to boot.
Banias | Dothan | Yonah | Merom | Merom+ | |
| Cores | 1 | 1 | 2 | 2 | 2 |
| Manufacturing Process | 130nm | 90nm | 65nm | 65nm | 65nm |
| FSB | 400MHz | 400/533MHz | 533/667MHz | 667MHz | 667/800MHz |
| L2 Cache | 1MB | 2MB | 2MB | 4MB | 4MB |
| Thermal Design Power | 25W | 21W/27W | 31W | 34W | 35W (42W High Performance) |
| Platform Name | Carmel | Carmel/Sonoma | Napa | Napa | Santa Rosa |
Asus reportedly has a BIOS in the works to solve the problem. However, this may not be true for all manufacturers.
