1-8 1756-MVI Module Overview
See chapter 6 for more information.
Operating System
The 1756-MVI module contains a General Software Embedded DOS
6-XL operating system. This provides DOS compatibility along with
real-time multitasking functionality. The operating system is stored in
Flash ROM and is loaded by the BIOS when the module boots.
DOS compatibility allows development of applications using standard
DOS tools, such as Borland™ or Microsoft™ C/C++ compilers. User
programs may be executed automatically on powerup by loading
them from either the CONFIG.SYS file or an AUTOEXEC.BAT file.
See the General Software Embedded DOS 6-XL Developer's Guide for
more information.
IMPORTANT
DOS programs that try to access the video or
keyboard hardware directly will not function
correctly on the 1756-MVI module. Only programs
that use the standard DOS and BIOS functions to
perform console I/O are compatible.
