	Expanded memory - Wikipedia, the free encyclopedia
		Expanded Memory is memory on an IBM PC compatible computer that is used through the Expanded Memory Specification ("EMS") memory paging scheme, enabling access to extra RAM above the 1MB conventional memory area while the processor is in real mode.
		A 64K block of memory called a page frame could be set to "point" to any block of memory above the 1 megabyte mark; software would utilize this 64K block as desired, and then when a different block was desired, the EMS driver would point the page frame to a different 64K block.
		The technique of expanded memory access continued to be used by software through the early 1990s, when DOS extenders became mature and allowed the far simpler XMS scheme to be used.

		EMS or Expanded Memory Specification is an IBM PC memory paging scheme enabling access to memory other than conventional memory in real mode, through the use of an add-on peripheral holding the additional memory.
		Expanded memory is provided through a page frame of at least 64 kilobytes in the reserved memory address region.
		Accordingly, this specification is sometimes referred to as LIM EMS.

		So memory expansion boards appeared which utilised bank switching but different developers implemented them in different ways and no-one could agree on how they should be used.
		When the 80386 was released, yet another memory management method, known as extended memory specification, was introduced to use the memory above 1Mb.
		Memory can be used in either way depending on the contents of the startup files.

	EMS-Expanded Memory Specification (Site not responding. Last check: 2007-10-22)
		Expanded memory works by using some of the DOS reserved memory address space to access memory on the Intel memory board.
		The area of reserved address space used to access expanded memory is made up of 16Kb sections called pages.
		Having expanded memory requires that you have an Expanded Memory Manager (EMM.SYS for Intel memory boards), to "manage" the expanded memory.

	Computer Science and Networking Glossary-E
		The Expanded Memory Specification LIM 4.0 is the standard method of accessing expanded memory, and lets programs running on any of the Intel 8086 family of processors access as much as 32MB of expanded memory.
		The expanded memory manager creates a block of addresses into which data (held in memory above the 1 MB limit) is swapped in and out as needed by the program.
		Memory beyond 1MB on computers using the Intel 80386 and later processors, not configured for expanded memory.

		Also known as EMS (Expanded Memory Specification), expanded memory is a technique for utilizing more than 1MB of main memory in DOS -based computers.
		Until the release of Microsoft Windows 3.0 in 1990, expanded memory was the preferred way to add memory to a PC.
		The alternative method, called extended memory, was less flexible and could be used only by special programs such as RAM disks.

	Expanded Memory (EMS)
		When the contents of a particular part of expanded memory is needed by the PC, it is switched into one of these areas, where it can be accessed by programs supporting the LIM specification.
		This concept is called bank-switched memory, and in a way is not all that different from virtual memory, except here the swapping isn't being done to disk but rather to other areas of memory.
		In addition to being slow and cumbersome, using extended memory for EMS makes it unavailable for use as extended memory by other applications, and the page frame wastes 64 KB of the upper memory area that could be used for drivers.

		Bottom-up memory allocation works by checking for a header at the start of extended memory stating that K of RAM is in use.
		After a program actually asks for XMS memory, HIMEM.SYS uses its Interrupt 15h hook to notify programs that only the amount of extended memory specified by /INT15=xxxx, minus the HMA (64K), is available for use.
		In MS-DOS versions 4.x, you can place the disk buffers in expanded memory by using the /X switch; however, this is not recommended because of problems that may arise.

		The Expanded Memory Specification LIM 4.0 let programs running on the Intel family of processors access as much as 32MB of expanded memory.
		The expanded memory manager (EMM) creates a block of addresses into which data (held in memory above the 1MB limit) is swapped in and out as needed by the program.
		In other words, a 64KB segment of addressable memory creates a small window through which segments of expanded memory can be seen, but only one segment at a time.

	EMS
		Expanded Memory Specification, EMS is a specification that allows IBM compatible computers to access more than the 1MB.
		However, because of out of memory issues still being encountered by users LIM EMS was created.
		Developed by AST, Intel, Lotus and Microsoft, XMS is short for eXtended Memory Specification and allows software access to more then one 1MB.

		QEMM, the Quarterdeck Expanded Memory Manager by Quarterdeck, was a popular memory manager for the DOS operating system.
		Many DOS programs required a high amount of conventional memory, and QEMM helped to increase the amount of free conventional memory by loading programs to the UMBs.
		Microsoft released comparable but simpler memory managers of its own - HIMEM.SYS for XMS and EMM386.EXE for EMS with Windows 3.0 in 1990 as well; they could be used outside of Windows sessions; earlier Windows/386 2.1 included a built-in EMM which offered EMS to DOS windows during Windows sessions only.

		(Expanded Memory Specification) A bank-switched memory management scheme developed by Intel, Lotus, and Microsoft that allows MS-DOS applications (normally limited to 640K of memory) to access vast quantities of memory.
		Memory that conforms to this standard is often referred to as expanded memory.
		EMS memory has been all but made obsolete by protected-mode operating systems such as Windows.

		This must be available within the upper memory block (UMB) between 640 KB and 1 MB.
		To disable the memory in a DOS session, you need to find the address of the 3270 adapter, by using the PS/2 Reference diskettes.
		This allows EMS to use this memory, if there is enough of it near this range.
