Since our PCs cannot address extended memory
0 protocol, while others are written to use extended memory
via XMS protocol.
For the most part, exTEnded memory
can the used only for RAM disks, disk caching software, and certain Windows uses, unless it is converted to exPAnded memory.
If a dedicated power program such as Algor is being run, however, running with a little cache and the maximum amount of extended memory
should be considered.
It uses the computer's conventional memory and any available expanded or extended memory
For example, for the T1000, the battery capacity is 1300 mA Hours; the average total drain for a system with extended memory
and a modem is 328 mA, and the Floppy disk consumes 389 mA; based on these assumptions, a fully charged battery should last just under four hours.
What makes extended memory
work is the chips that plug into the board.
Other features of the M29DW640D include 25ns or 30ns page-read access times, optional 12V fast programming, five fast-program commands, and a 256-Byte extended memory
block for storing security or other information.
SYS, Microsoft's extended memory
manager, cannot be loaded using DEVICEHIGH or LOADHIGH because, until it is loaded, DOS does not even know extended memory
OPT-NET Lite's CD-ROM data caching enables network users to store recently and frequently-used applications and data in high-speed extended memory
(XMS), for almost instant retrieval.
A number of memory management programs will allow extended memory
to simulate expanded memory.
