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.

Famous quotes containing the words huge, big, real and/or mode:
“Only one ship is seeking us a black- Sailed unfamiliar, towing at her back
A huge and birdless silence. In her wake
No waters breed or break.”
—Philip Larkin (1922–1986)
“The final key to the way I promote is bravado. I play to people’s fantasies. People may not always think big themselves, but they can still get very excited by those who do. That’s why a little hyperbole never hurts.”
—Donald Trump (b. 1946)
“We must have a real living determination to reach holiness. “I will be a saint” means I will despoil myself of all that is not God; I will strip my heart of all created things; I will live in poverty and detachment; I will renounce my will, my inclinations, my whims and fancies, and make myself a willing slave to the will of God.”
—Mother Teresa (b. 1910)
“The body sins once, and has done with its sin, for action is a mode of purification. Nothing remains then but the recollection of a pleasure, or the luxury of a regret.”
—Oscar Wilde (1854–1900)
