<p>It seems that as soon as I enable x86 paging the VGA buffer is not accessible anymore (because 0xb8000 is not identity mapped yet?). So essentially the test_paging routine doesnt print anything... so my thinking tells me the identity map is the first thing to do after enabling paging, yet its the subject of the next chapter, am I not getting something?</p></div><div class="isso-comment-footer"><span class="votes">0</span><a href="#" class="upvote"><!-- Generator: IcoMoon.io --><svg width="16" height="16" viewBox="0 0 32 32" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" fill="gray">
