There are bugs in your program.  You cannot terminate from a real mode 
interrupt, which you are effectively doing with the return register to 
int 24.  You also can't free the RMCB while you are using it.  The 
only option with Int 24 in protected mode is to set a flag and continue
(or use the HW interrupt to exception kluginess).  

Int 24 is supposed to be reflected to PM by the DPMI provider - but the
reason it never got done in CWSDPMI is that Int 24 is of so little use
since you can only store the error info anyway.
