Example

The 80486 Paging Subsystem was very similar to the 80386 one. It was backward compatible, and the only new features were to allow for memory cache control on a Page-by-Page basis - the OS designers could mark specific pages as not to be cached, or to use different write-through or write-back caching techniques.

In all other respects, the "80386 Paging" example is applicable.
