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:
“Then came the Lord Chamberlain with his white staff,
And all the people began to laugh;
And then the Queen began to speak,
‘You’re welcome home, Sir Francis Drake.’”

“At twelve, the disintegration of afternoon
Began, the return to phantomerei, if not
To phantoms. Till then, it had been the other way:
One imagined the violet trees but the trees stood green,
At twelve, as green as ever they would be.
The sky was blue beyond the vaultiest phrase.”
—Wallace Stevens (1879–1955)
“We must return optimism to our parenting. To focus on the joys, not the hassles; the love, not the disappointments; the common sense, not the complexities.”
—Fred G. Gosman (20th century)
