Many motherboard manufacturers are replacing BIOS+MBR with UEFI+GPT. UEFI uses a GPT table instead of the MBR"
=== Boot from USB ===
== 1a. Create a FreeDOS USB Stick with RUFUS ==
  *RUFUS 4.9.2256:
    *Drive Properties:
      *Boot selection: "FreeDOS".
      *Partition scheme: "MBR".
      *Target system "BIOS ( or UEFI-CSM ).
      *[x] List USB Hard Drives.
      *[x] add fixes for old BIOSes ( extra partition, align, ect. ).
      *<del>[_] Use Rufus MBR with BIOS ID "0x80 Default"</del>.
    *Format Options:
      *Volume label "FREEDOS".
      *File system "FAT32 ( Default )".
      *[x] Quick format
      *[x] Create extended label and icon files.
  *Update the FreeDOS installation.
    *Copy "HIMEMX.EXE" and "MEM.EXE" from the ISO file of the "LiveCD" download.
  *Modify CONFIG.SYS, add as first line:<code>
DEVICE=HIMEMX.EXE
</code>
=== 1b. Alternatively, create a FreeDOS USB Boot Stick manually ===
  *[[http://superuser.com/questions/1388931/how-to-install-freedos-onto-a-usb-flash-drive|StackExchange "How to install FreeDOS onto a USB flash drive?"]].
=== 2. Configure UEFI / CSM BIOS on Notebook "ASUS K95VB", for FreeDOS Boot ===
  *"Boot / Boot Configuration - Launch CSM [Enabled]".
    *This causes the option "Boot / Boot Configuration - Fast Boot [ Disabled ]" to disappear from the menu screen.
  *"Security / Secure Boot Control [Disabled].
  *After a reboot, a USB stick with FreeDOS might appear as
=== 3. FreeDOS Boot Process Preparation & Boot Process ===
  -Insert the FreeDOS USB Stick.
  -Reboot the computer.
  -Press the key at startup to jump to BIOS ( with ASUS computers, press key "F2" ).
  -Check that there are 2 Items "UEFI: PMAP" and "PMAP". With ASUS UEFI / CSM notebooks there are now two items at:
    -"Boot - Boot Option Prorities" - "UEFI: PMAP", " PMAP".
    -"Save & Exit - Boot Override" - "UEFI: PMAP", " PMAP".
  -Boot selection:
    *Select " PMAP" ( and not "UEFI: PMAP" ) as "Boot Option #1" to start the computer with FreeDOS next time.
    *Or click on "PMAP at "Boot Override" to start FreeDOS immediately.
=== 4. FreeDOS Memory Usage, displayed by the MEM.EXE Command ===
  *Without HIMEMX.EXE: 471K of 629K are free.
  *With HIMEMX.EXE: 546K of 629K are free.

Der Entwickler Hein-Pieter van Braam-Stewart hat solch einen Laptop gekauft und näher untersucht, wie er in seinem Blog berichtet. Demnach läuft auf dem Gerät FreeDOS nicht nativ, weil es kein BIOS von UEFI-CSM gibt. Stattdessen läuft FreeDOS in einer VM und zwar als alleiniges Fenster im Vollbildmodus auf einem extrem rudimentären XFCE-Desktop in Debian".

===== Abandonware =====
  ***FANSI-CONSOLE** by Hersey Micro Consolting, Inc. A special ANSI / VT100 video driver for MSDOS applications. Version 3 is now shareware, version 4 is (still ?) commercial. I own a full license and got both version 3.01k of 04.10.1991 and version 4.00j of 21.11.1991. Are there any newer versions out ?
  ***THE LAST BYTE** by Key Software Products. A special MSDOS "upper memory" manager for 386 / 486 / 586 boards with specially supported chipsets, so it just runs on selected computer mainboards. The shareware version may be turned into commercial versions by entering a serial number. I own a full license key and got version 2.11 of 11.08.1992 and version 2.50 of 30.08.1994. I am still looking for a newer version, there must have been such !
  ***LDEVICE - Load Device Driver** V2.0 by Adlersparre & Associates Inc., 1803 Douglas Street, Victoria, BC, Canada. A special MSDOS tool to load MSDOS device drivers at runtime.
