	Expanded memory - Wikipedia, the free encyclopedia
		Expanded memory was a common term for several incompatible technology variants.
		EEMS, a competing expanded memory management standard, was developed by AST Research, Quadram and Ashton-Tate.
		A 64 KB block of memory called a page frame could be set to "point" to any block of expanded memory.

	MS-DOS Memory Issues
		Expanded memory is divided into 16KB pages, which are mapped into a predetermined area in the first megabytes of address space (the page frame) as the application requests.
		Upper memory blocks are not connected with conventional memory, and cannot be directly used by applications which have not been made aware of its existence.
		Software that will convert extended memory to expanded memory on an 80286 machine is not written to use the special hardware built into the 80386 chip, so the same type of performance penalty may apply.

	Extended memory - Wikipedia, the free encyclopedia
		Extended memory refers to memory above the first megabyte of address space in an IBM PC with an 80286 or later processor.
		In this case, the extended memory is provided by a supervising protected-mode operating system such as Microsoft Windows.
		The memory is "protected" in the sense that memory segments assigned a local descriptor cannot be accessed by another program because that program uses a different LDT, and memory segments assigned a global descriptor can have their access rights restricted, causing a hardware trap (typically a General Protection Fault) on violation.

	Memory management in PCs: the eighteen most misunderstood acronyms. (The CPA & the Computer)
		For example, the difference between expanded memory and extended memory should be highlighted by emphasizing the "PA" of exPAnded or "TE" of exTEnded--otherwise the words are identical.
		Random Access Memory (RAM) in a PC starts with the first megabyte (1024k) of RAM divided into lower (conventional) memory, which is the base 640k found in most machines, while the remaining 384k of the first megabyte is known as High Memory.
		ExPAnded memory is any memory that can be mapped- into the base 640k; that is, DOS can be tricked into accepting exPAnded memory as if it were conventional 640k memory.

	expanded memory definition - isp.webopedia.com - The Glossary for Internet Service Providers
		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.

		Conventional Memory is the memory range between 0 and 640KB, which is directly accessible to DOS applications.
		On a 286 system, an expanded memory board can be installed, which installs physically addressable memory into this range of upper memory.
		Memory managers for the 80386 can map memory into the upper memory area so that TSRs can be loaded outside of the standard 640KB.

	msdos memory types
		Expanded memory is available for all processor types from the 8086 PC to the 486DX PC.
		Peripheral cards often have memory on board, like video cards which have memory which hold the screen image, and a small ROM which hooks itself into the ROM BIOS to provide support for special displays (VGA display cards are a good example).
		As memory chips expanded in size, it became common for 2MB or 4MB of memory to be fitted to motherboards.

		Expanded memory is one way DOS can be fooled into using memory beyond the 640KB system memory.
		Memory is the most common cause of frustration for PC users, probably because it is so vital to a PC's operation and performance.
		By setting memory as drive space, you may be able to detect and isolate a memory problem to a specific chip.

		EXPANDED MEMORY SERVICES FUNCTIONS DEFINED IN EMS 3.2 SPECIFICATION Interrupt 67h Function 40h Get Manager Status LIM Function Call 1 Returns a status code indicating whether the memory manager is present and the hardware is working correctly.
		It appears that the intended use for this function is to return the version of the vendor implementation of the expanded memory manager instead of the specification version.
		Functions 10 and 11 are specific to the hardware on Intel expanded memory boards and may not work correctly on all vendors' expanded memory boards.

	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.

		EXPANDED MEMORY: memory which conforms to LIM EMS (Lotus-Intel-Microsoft Expanded-Memory-Standard) which currently is at 4.0 and is unlikely to change much more.
		Expanded memory is divided into 16Kb pages, which are mapped into some predetermined area in the first megabytes of address space called the page frame, as the application requests.
		UPPER MEMORY BLOCKS: term for memory found between A0000-FFFFFh (640Kb to 1024Kb) in the CPU address space which are NOT connected with conventional memory, and cannot be directly used by applications which have not been made aware of UMB's.

		Values for memory are in the range 64 through the lesser of either 32768 or the amount of extended memory available when EMM386 is loaded.
		When it is loaded, EMM386 reserves the amount of memory specified by the MIN switch for use as EMS/VCPI memory (the default value is 256K).

	Beating the 640 KByte Squeeze
		The first such technique is known as Expanded Memory System, Version 3.2, and was jointly developed by Lotus, Intel and Microsoft, with the primary goal of allowing 1-2-3 access to bigger spreadsheets.
		Because the memory is paged, special code has to be provided (in the form of a device driver) to select and enable the appropriate pages.
		Furthermore, because this memory is outside the User Memory area, the DOS operating system is unaware of it, and it cannot be used to contain program code such as co-resident utilities (e.g Sidekick, Lotus Metro).

	Running Both Extended and Expanded Memory on Your Computer
		For example, you may want to run MS-DOS in the high memory area (which is part of extended memory) while also running applications in expanded memory.
		If your memory board can be configured as expanded or extended memory, configure the board so that it provides only extended memory.
		If your 80286 computer has an add-in memory board, you might be able to configure the memory board so that it provides both expanded and extended memory.

	UMB-Upper Memory Blocks (Site not responding. Last check: 2007-10-22)
		But, a lot of LIM 4.0 compatible expanded memory boards (such as Intel memory boards) automatically try to provide as large a page frame as possible, up to 128K (if there are no ROM's within this range also using some of this space), within the C000-DFFF range.
		These additional pages of expanded memory in the page frame can be used to create Upper Memory Blocks, which are blocks of memory that can be used to load device drivers and TSR's into them in order to free up more conventional memory for your applications.
		These memory managers require that the available Upper Memory Blocks first be made mappable by the combination of a LIM 4.0 Expanded Memory Manager and a memory card such as Intel's EMM.SYS device driver and an Intel Above Board.

	Expanded Memory Manager - EMM
		Short for Expanded Memory Manager, EMM is a device driver that allows MS-DOS computers to use expanded memory.

	Adding Extended or Expanded Memory to CONFIG.SYS
		If your particular problem is not enough memory in an application, to say that "you need more memory", is not quite true as the application that you use requires memory to be formatted differently (extended, expanded, etc.).
		Well, this could be a result of many things, but most likely it is because you are either not allocating the proper type of memory to the program (expanded instead of extended, etc.), or you don't have any/enough drivers loaded into high memory.
		To free up the base memory, a "Memory Manager" needs to be loaded so that devices and executable's can be loaded "High" (i.e.

		Ajnin, yes I have done what you said, in the memory it says that "this computer is not configured for expanded memory in ms-dos mode" (I have mentioned this in a previous comment also).
		I still think it's something stuck in upper memory from a BIOS setting that is reserving the space on one machine that is needed for Win98 to manage expanded memory without help.

	The PC Guide Discussion Forums - View Single Post - What is expanded memory?
		On those old 8088 type machines you had to use a tool (QEMM comes to mind) that would allow you to configure blocks of upper memory or expanded memory addresses above the "real memory" 64KB line contiguously.
		By setting your upper memory blocks this way programs like Framework, DBase and Lotus 1-2-3 could run spreadsheets and perform database operations by accessing upper memory and avoided running out of memory as fast.
		The problem back then was the software resource demand on the PC was always way ahead of the hardware technology for running business applications we take for granted now such as Word or Excel.
