Every V86 segment gets the same treatment: access rights 0xE200 (Present, DPL=3, writable data segment), base = selector shifted left by 4, and limit = 64 KB. The microcode loops through all six segment register caches using a counter, applying the same fixed descriptor to each one. This is pure real-mode emulation, enforced at ring 3 with full paging protection underneath.
Segmentation maps a logical address (a 16-bit selector plus a 32-bit offset) to a 32-bit linear address, enforcing privilege and limit checks along the way. Paging then translates that linear address to a physical address, adding a second layer of User/Supervisor and Read/Write protection. The two layers are independent: segmentation is always active in protected mode, while paging is optional (controlled by CR0.PG).。Line官方版本下载是该领域的重要参考
