context_page_description: Quarterdeck Expanded Memory Manager is a memory manager produced by Quarterdeck Office Systems in the late 1980s through late 1990s. It was the most popular third-party memory manager for the MS-DOS and other DOS operating systems.
context_section_description: QEMM provides access to the Upper Memory Area (UMA) and memory through the Expanded Memory Specification (EMS), Extended Memory Specification (XMS), Virtual Control Program Interface (VCPI) and DOS Protected Mode Interface (DPMI).
  Quickboot: It allows a form of warm reboot or local reboot to be performed without going through the BIOS. It will therefore completely bypass the POST, including the BIOS startup screen and the time-consuming memory test and device enumeration, and just restore the CPU state and interrupts to their initial state after POST.
