The FreeDOS kernel and most programs are fully compatible with 8086* and higher computers, so if the embedded system is similar enough standard IBM compatibles (generally AT class or modern systems are used for development and testing, but older PC/XT systems should work) then yes FreeDOS can be installed* and used on an embedded system. * The kernel can be compiled with 8086, 80186, or 80386 specific optimizations (mostly just effect file size); same for FreeCom (our command.com replacement), though the latest FreeCom is usually compiled with 80186 optimizations due to size/features issues. * It might be easier to do a manual install for embedded systems than the CD [or diskettes] based install; that is download the latest kernel, FreeCOM, format, fdisk, and manually do the fdisk/format/sys sequence, then copy over any other programs (mode, keyb, diskcopy, ...) you need. > possible that freeDOS work on an embedded system without BIOS? > Not really. Currently the kernel and many of the utilities make extensive use of both BIOS interrupts and the BIOS data area (equipment flags, etc). It is possible to remove/alter the need for BIOS, but it would probably be a lot of work (but full source is there if you wish to look through and see for yourself and/or do the changes needed). I'm always open to accept patches that make FreeDOS more friendly for embedded use. Though most things would need to be compile time selected (#ifdef SOME_FEATURE #endif), such as FAT32 support and WIN3 support currently are. If you have any other questions feel free to ask. If you can provide more specific details about the operating environment others may be able to provide better information.
