MS-DOS (any version from 3.0 & up)
Modify your CONFIG.SYS file to allow a boot-up configuration in which EMM386.EXE, HIMEM.SYS, RAMDRIVE.SYS, and any disk caching programs are not present.
Alternately, create a boot disk with the FORMAT /S command to boot up in a minimal environment.
Disable DOUBLESPACE if it is enabled.
Change to the directory with turbocnc.exe and execute the program.
Windows 3.1
Edit the WIN line and any drivers from your autoexec.bat and config.sys files in order to present a clean boot to DOS.
Run TurboCNC from the DOS prompt. If you're still using Win3.1 this far into the 21st century, we assume that you know what you're doing here. Generally, the instructions are the same as for MS-DOS above.
Windows 95/98
From the desktop, pick Start | Shut-down | Restart in MS-DOS mode
Change to the directory with turbocnc.exe and execute the program using the DOS commands
CD \TCNC or similar for your system, then TURBOCNC
Alternately, you can hold down the CTRL key (or sometimes F8) while your computer boots up. A short text menu will appear with some boot options. Pick Command Prompt Only, and run as above. If TurboCNC gives you an EMS/XMS driver warning, do it over and pick Command Prompt Safe Mode instead.
Windows NT / 2000
TurboCNC will not drive your CNC system reliably as direct access to the hardware is not allowed under these operating systems. You can, however run TurboCNC under the command prompt to familiarize yourself with it, and to 'Dry Verify' parts files. All of the screen shots in this document were gathered by running Turbo CNC on a Windows 2000 system and performing a 'Print Window'.
TurboCNC can run on a dual boot system with DOS. Consider formatting a disk partition with FAT16 rather than running solely from a floppy disk. On some systems using floppy drives only TurboCNC has had problems due to drive access times.
Windows XP
You'll need to create a real-mode boot disk for TurboCNC Get a blank floppy disk out.
• From the desktop hit Start | My Computer | Floppy (A) [or other letter as appropriate for your system]
• Insert the disk, then hit File | Format
• Check the box that says "Create MS-DOS boot disk" and hit OK to format

Expand and copy the TurboCNC files to the floppy.
Reboot the computer with the floppy in drive A
Execute TurboCNC at the A:\> prompt.
