What hardware does linux support?

As of 2006, the current version is 4.1. Yellow Dog has tried to provide simple and working hardware support, as well as a system that runs fast on older machines. Due to the closed nature of Apple Computer however, Yellow Dog Linux has been unable to get all hardware features working with current Apple products. Most notably, the AirPort Extreme (Apple's 802.11g wireless cards) on Apple PowerBooks and iBooks will not work in Yellow Dog Linux without modifications to the kernel.
