The Wish List ( santa@osdev.org ;)

Below you will find a list of items that we 'need' on the OSDev wiki. They are divided in specific categories. Feel free to add a new item to the list if you would like more information on a specific topic.

If you want to help the OSDev wiki out or have some spare time, feel free to log in and add information about any of the requested topics or help maintain the OSDev wiki.
