i've got a MS-DOS Assembly programming book. its has a massive appendix with nice documentation of interrupts and the functions they have. some of these are BIOS and some are MS-DOS. i know some are BIOS as i've used them while playing around making my own OS. what i really want to know which interrupts belong to the BIOS and which to MS-DOS. i know there is a certain range of interrupts which can be customizable by the OS or program on the OS. could anyone give me an idea which interrupts are dependant on MS-DOS and which aren't?

BIOS's ones are 10h - 1Ch, 4Ch, and following are used as tables: 1D, 1E, 1F, 41h 46h.

Note that all these can be "overloaded" by DOS routine

Also if you need to sign a agreement form, before using them they are Dos Laughing .
