hi!

   mapping.address = 0xDE000000;
   mapping.size = 0xFFFFFF;
   __dpmi_physical_address_mapping(&mapping)
   // ... code removed ...  ( creating selector on mapping address and name
it msel )
   movedata(msel,0,screenSelector,0,640*480);
   this code crashed, but if i set mapping.address smaller ie.
640*480,640*480*2 etc. it's ok
   why ?   Thanks!
