“Our 64-bit architecture designs exit reset mode in the same state as the original 8086 and require a series of transition codes to enter 64-bit mode,” Intel says. Once implemented, these modes are used in modern applications or operating systems.”

Therefore, it can be easily seen that removing the old Intel architecture will have advantages, some of which we will mention below:

  • Using a simplified 64-bit partitioning model to support the partitioning of 32-bit programs in line with what modern operating systems already use.
  • Remove loop 1 and 2 and deprecated segmentation features.
  • Remove support for 16-bit addressing.
  • Removal of support for access to the input and output port of ring 3.
  • Limiting APIC usage to X2APIC and removing legacy 8259 support.

Intel advises people who are interested in running older operating systems and software on the company’s newest hardware to take advantage of virtualization-based solutions.
