I must say that I find the lines confusing. I don't understand what they mean. I think it would be nice to have a complete memory lookup written down step by step in text form. e.g. we're trying to look up the address 0xAA in virtual memory, the current page table pointer is 0xBB, therefore we're reading directory entry from the address 0xCC the directory address contains (...) etc.
