Concepts and technologies are disclosed herein for providing a modular and enhanced kernel device manager. Control is passed to the kernel device manager during POST after an enhanced device initialization manager has performed device initialization. The kernel device manager configures and manages devices enumerated by the enhanced device initialization manage, and groups these devices. In some embodiments, the devices are groped as input devices, output devices, and/or storage devices. The kernel device manager also classifies the devices and links the devices with a proper class-specific kernel such as an input device kernel, and output device kernel, and/or a storage device kernel. The devices can be linked to the proper class-specific kernel via a class-specific communication pipe such as an input pipe, an output pipe, or a storage pipe.
