Is it possible to call the XMS handler from protected mode and allocate some
memory? Or is the memory already eaten by the DPMI host?

XMS specification requires that a real-mode handler is called:

Example:
   mov ax, 4310h
   int 2Fh      ; get handler address
   mov word ptr [XMSControl], bx
   mov word ptr [XMSControl+2], es

   mov ah, 00h
   call [XMSControl]  ; Get XMS version number

Now, how do I do this in protected mode?

Thank you,
James
