HIMEM.SYS
HIMEM.SYS is an eXtended Memory Manager (XMM) conforming to eXtended Memory Specifications
(XMS), version 2.0,
HIMEM.SYS uses 64 K byte of the high-memory area (HMA) at the beginning of Extended memory to store a
single TSR program or device driver, or it uses this area for data storage. This effectively increases the size
of conventional memory for use by your main application program. In order to use HMA, you must have at
least 64 K byte of Extended memory.
To install HIMEM.SYS in its simplest form, include the following command line in your CONFIG.SYS file
before any other device commands that use Extended memory:
DEVICE=C:\DOS\HIMEM.SYS
In this form HIMEM.SYS will use default values, and access to HMA will be on a "first come-first served"
basis. The first device driver or TSR under 64 K byte which supports HMA will go into HMA. Other
device drivers will go into conventional memory.
