What is DOS Protected Mode? / DOS Extenders [Byte Size] | Nostalgia Nerd
DOS Extenders! Most of us are familiar with seeing DOS/4GW upon starting our favourite DOS games, but many of us didn't stop to think what this little "Dos Extender" did, or how it opened up a wealth of games for our protected mode systems. Of course many of us did, myself included, and like other Protected Mode Interfaces, DOS/4GW operated under the DPMI specification designed to allow the *new* 286 and 386 machines to make use of memory over 1MB. Before that Real Mode DOS applications could only make use of memory in the PC up to 1,024KB. This video explores the makeup of a PC memory, conventional memory, extended memory and the reasons behind the DOS Protected Mode Interface.
