It's an open source clone of MS-DOS, which is a 16 bit real mode OS.
It can see up to one megabyte of RAM as usable memory.  Beyond that,
you must load HIMEM.SYS and possible EMM386.EXE to get access to XMS
or EMS.

I have FreeDOS on an old notebook with 256MB RAM, and use XMS memory
to support a ramdisk and a cache.

No, and doesn't really need one.  It's not a virtual memory OS.
