sorry, i am beginning to learn something new. never knew there is
such a system call vm86(). (man vm86 to read more), and the
implementation is in linux kernel's vm86.c, which runs 16bit under
32bit protected mode task.
and from the man pages of vm86, dosemu is using this API. So I think
you
technically, 16bit cannot access > 16bit of RAM for i368 CPU. so the
answer is technically impossible, CMIW.
and linux kernel only runs on 32bit and 64bit, but u want to execute
16bit insn? eg, using QEMU to run 16 bit application? So i think
your questions sounds like: how to execute insn

Hi, all
I want to enter v86 mode and switch to VGA Mode 13h to draw some pictures.
Now i can enter v86 mode with IRET instruction setting VM flag in the eflags
register.
But since v86 mode supports only 16-bit address, how can i let the cpu
executes instructions beyond 0x10 which includes set
