Here is my situation: I am running Windows XP, and would like to build _and_ run _most_ of my DJGPP applications in XP. However, I also want to build (in XP, if possible, for convenience) a "production" application that will run in pure MS-DOS (probably via a boot disk). (I need DOS for easy access to hardware interrupts, and for more precise timing that multi-tasking Windows can't provide.) Having read the FAQ, I am not sure I "need" long filename support, if that simplifies things. At any rate, my questions are these: 1. When I build a DJGPP application, will it run, as is, in either XP or MS-DOS? I ask because the zip picker gives a different set of files to install for the two environments (namely, long filename support or DPMI server). For example, does unpacking csdpmi5b.zip result in executables being built which will _not_ run in XP? 2. To get to a pure MS-DOS environment, I plan to use the boot disk created by Windows Explorer in XP. Have others had success with this, or should I look elsewhere (bootdisk.com, etc.)? I am still trying to get smart on the differences between Windows and DOS, so any comments are appreciated. Thanks, Eric Farmer
