The problem is that DOSEMU2 give a general protection error...
I was expecting just the program to end in an exception... not the full DOSEMU2.

That's a bad example I guess... it does indeed run under DOSEMU2 ... 
but make DOSEMU2 crash:
ERROR: general protection at 0x7f1952c6d798: 2e while collecting 
information.


That is to be expected. As there isn't really a Dell BIOS to update 
under DOSEMU, that should be common sense. You are trying to gain write 
access to a piece of memory that is simply protected by the OS (and/or 
DOSEMU)...

That's a bad example I guess... it does indeed run under DOSEMU2 ... but make 
DOSEMU2 crash:

ERROR: general protection at 0x7f1952c6d798: 2e while collecting information.___
