Return
With the arrival of expanded memory boards and especially of Intel 80386 processors in the second half of the 1980s, it became possible to use memory above 640 KB to load TSRs. This required complex software solutions, named expanded memory managers, but provided some additional breathing room for several years. Famous memory managers are QRAM and QEMM by Quarterdeck, 386Max by Qualitas, CEMM by Compaq and later EMM386 by Microsoft. The memory areas usable for loading TSRs above 640 KB are called "upper memory blocks" (UMBs) and loading programs into them is called loading high. Later, memory managers started including programs which would try to automatically determine how to best allocate TSRs between low and high memory (Quarterdeck's Optimize or Microsoft's MemMaker) in order to try to maximize the available space in the first 640 KB.

Famous quotes containing the word return:
“We draw our Presidents from the people. It is a wholesome thing for them to return to the people. I came from them. I wish to be one of them again.”
—Calvin Coolidge (1872–1933)
“Each work of art excludes the world, concentrates attention on itself. For the time it is the only thing worth doing—to do just that; be it a sonnet, a statue, a landscape, an outline head of Caesar, or an oration. Presently we return to the sight of another that globes itself into a whole as did the first, for example, a beautiful garden; and nothing seems worth doing in life but laying out a garden.”
—Ralph Waldo Emerson (1803–1882)
“Retirement requires the invention of a new hedonism, not a return to the hedonism of youth.”
—Mason Cooley (b. 1927)
