There is however one thing you can do. You can make your program such that it doesn't use any DOS services, load it from a bootdisk (having appropriate bootsector of course) and thus skip any crap that can possibly chain to ISRs. If you're doing your program with 32-bit DJGPP, then you have a little problem here... You either need to setup PMode yourself or make the program a 16-bit real-mode one. Perhaps you may use my BootProg bootsectors (they load and run standard .COM/.EXE programs from FAT12/16 disks) or OS for Dummies Loader (which in addition can load and run a compiled .O (COFF) image produced by DJGPP GCC/LD). For more info see my homepage (PMode section). Good Luck -- Alexei A. Frounze alexfru [AT] chat [DOT] ru http://alexfru.chat.ru http://members.xoom.com/alexfru/ http://welcome.to/pmode/
