Starting with the Pentium model, Intel 80×86 microprocessors introduce extended paging ,
which allows page frames to be either 4 KB or 4 MB in size.Extended paging is enabled by setting the Page Size flag of a Page Directory entry.The paging unit divides the 32 bits of a linear address into two fields:
1.Directory
The most significant 10 bits
2.Offset
The remaining 22 bits
