This driver works on a broad range of panasonic laptops, such as Let's note series and Tough book series. I had discussed bios writers in the Panasonic 2 yrs ago, they said they keeps backword compatibility for their products, at least after CF-R1/T1/W1/Y1 toughbook/let's note series. They will adopt new acpi specification when microsoft os adopt it. That's why recent model, such as CF-W6/W7, can not control lcd brightness through this driver but can through generic video driver. I originaly write driver in reverse engineering basis, but at that time, bios writer provided me some specification.
