In actual code the program will start normally from runtime library (i.e. To print out characters you use DOS interrupt calls (INT 21H).Īctual Os's are 32/64 bits they use a different memory layout, and are normally located at 0x40000, but can be reorganized by linker. Specifically the code you used starting with an ORiGin metainstruction denotes the writing of a binary '.com' executable (by default located at adrress 0x100).
