Intel x86 Assembly Language & Microarchitecture Paging - Virtual Addressing and Memory 80486 Paging


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.
