Huge Versus Big Real Mode
As described above, unreal mode usually involves using one or more data selectors to address data in memory more efficiently. This has been common practice and often referred to as "big" real mode. "Huge" real mode is attained by, in addition, loading the code selector (CS) from a descriptor allowing access to the whole memory and having the 32-bit attribute ("D" bit) set to one. This rarely used "mode" presents some advantages but it is more difficult to set up, since real mode interrupts do not automatically preserve the high sixteen bits of the extended instruction pointer, EIP.

“Perchance the time will come when we shall not be content to go back and forth upon a raft to some huge Homeric or Shakespearean Indiaman that lies upon the reef, but build a bark out of that wreck and others that are buried in the sands of this desolate island, and such new timber as may be required, in which to sail away to whole new worlds of light and life, where our friends are.”
