JIO_OK ("jump if I/O OK") tests whether CPL ≤ IOPL. The same check gates PUSHF, POPF, INT n, and IRET. The monitor then emulates each instruction as appropriate: maintaining a virtual interrupt flag per V86 task, reflecting software interrupts through the real-mode interrupt vector table, virtualizing I/O accesses, and so on.
The 80386 introduced Virtual 8086 (V86) mode -- allowing real-mode DOS programs to run inside protected mode under OS supervision. While not full virtualization in the modern sense, V86 was the first practical hardware-assisted mechanism on x86 for running legacy software in a protected environment -- used widely in Windows 3.x and Windows 9x.，更多细节参见谷歌浏览器【最新下载地址】
