Hello,

I'm entering Pmode now, but I would like to make a routine that checks to see if we are realy in Pmode. How can I check this?

check the appropriate bit inside the flags that you set to enter pmode. If it is 1, you're in pmode, else your in real mode.

Do you mean you want to check whether or not you're in a vm86 session?  To check if you're all ready in pmode..

mov eax, cr0
and eax, 1
cmp eax, 0
je  not_in_pmode
; in pmode
