How to Enable 64bit Mode on x86: How to enable 64bit mode on the x86 platform. In this article we will enable a CPU to run in 32bit mode with paging enabled. In long mode page tables contain 8 byte entries compared to 4 byte entries in 32 bit mode. We need only one table which will host 16 entries (0x1000 / 0x1000 = 0x10 = 16) We will identity map these areas and use them to create tables.
