Don't use a 32 or 64-bit compiler if you expect 16-bit code.

Actually, it should be fine with GCC, if DS = ES and the code fits one segment. Isn't that what they do with GRUB?

Not without doing the hack that makes it emit 16-bit code.Love4Boobies wrote:Actually, it should be fine with GCC, if DS = ES and the code fits one segment. Isn't that what they do with GRUB?
The OP is executing 32-bit opcodes in 16-bit mode and wonders why the compiler is "broken". The problem gets ever more interesting when you end up using a mingw32 (educated guess) compiler to make a DOS .COM binary in a "bootloader" folder. Add to that that the OP can't even formulate a proper question chances are likely he doesn't even understand what he's doing - in which case guessing the right fix is rather dangerous.

Well, you just wasted both your hands on one stupidity. There might be more to come. 
That is, unless the OP finally gets the hint and stops posting symptoms of an unmentioned problem.

Both hands? Those were two one-handed facepalms
