HIMEM is a DOS device driver which allows DOS programs to store data in extended memory via the Extended Memory Specification (XMS). This device driver is of particular importance because various versions of Microsoft Windows that ran on top of the DOS operating system required HIMEM.SYS to be loaded to be able to run.
As of MS-DOS 5.0, HIMEM.SYS was introduced and could be used to load the DOS kernel code into the High Memory Area (HMA) to increase the amount of available conventional memory by specifying DOS=HIGH in CONFIG.SYS.
HIMEM.SYS provides access to the memory beyond the first 1 MB of space and thus is required by Windows 9x/Me in order to load the graphical portions of the operating systems. In FreeDOS, the matching file is named HIMEM.EXE and can be loaded from the FreeDOS configuration file named FDCONFIG.SYS or CONFIG.SYS.
