Take Control of Your OS at DOS Level

WinDOwS

Take control of your Windows 95/98/ME machine at DOS level!
After all Windows 95/98/ME is a MIXED (read "partially enabled") 32-bit AND 16-bit [for backward compatibility with MS-DOS (DOS16 and DOS32) and older 16-bit Windows/WfWG 3.xx (Win16) programs] Graphical User Interface (GUI) protected mode virtual environment [... sorry, Operating System ;)], which still depends on the good ol' MS-DOS 7.xx TSR modules (IO.SYS + COMMAND.COM), MS-DOS mode memory manager (HIMEM.SYS) and compatibility (legacy) drivers (IFSHLP.SYS) to load on top of the plain DOS command line based layer!
The good news is Microsoft released Windows XP (eXPerience)/2003/Vista/2008/7/8/2012, true 32-bit/64-bit multitasking, multithreading and Symmetrical MultiProcessing (SMP) graphical OSes, which do away once for all with the "ancient" 16-bit MS-DOS command line.
NOTE: Unfortunately Microsoft removed 16-bit application support from all Windows 64-bit (x64) OSes. ;-(
But the bad news is these advanced OSes do NOT support native/real/true/pure MS-DOS mode, necessary for some old DOS based programs/games that require exclusive access to memory/video/audio/network hardware resources, and most of which are still memory "hungry", especially the ones that canNOT run from a DOS session/box/window inside Windows.
Therefore master your CONFIG.SYS + AUTOEXEC.BAT command lines and your MSDOS.SYS + SYSTEM.INI parameters to BOOT into your system the way YOU want!
