 We first create the mapping for the page at `0x1000` by calling our `create_example_mapping` function with a mutable reference to the `RecursivePageTable` instance. This maps the page `0x1000` to the VGA text buffer, so we should see any write to it on the screen.
 
-Then we write the value `0xf021f077f065f04e` to this page, which represents the string _"New!"_ on white background. We don't write directly to the beginning of the page at `0x1000` since the top line is directly shifted off the screen by the next `println`. Instead, we write to offset `0x900`, which is about in the middle of the screen. As we learned [in the _“VGA Text Mode”_ post], writes to the VGA buffer should be volatile, so we use the [`write_volatile`] method.
