MZ

DOS-MZ was introduced with MS-DOS (not DOS v1 though) as a companion to the simplified DOS COM file format. DOS-MZ was designed to be run in real mode and reflects this, having a relocation table of SEGMENT:OFFSET pairings. A very simple format that can be run at any offset, it does not distinguish between TEXT, DATA and BSS. Since it was designed to run in real mode, its maximum filesize of code + data + bss is 1mb in size.

Operating Systems that use it: DOS, Win*, Linux DOS Emu, Amiga DOS Emu
