can i use it in real mode, if not, which int and how can i use it to run a file on the disk
well what i want is
the int
how to use it
if you could give me the info, that would be amazing, please no linksto other cites, i know there are alot of realy smart assembly people on here who can answer my question so please no links.

Of course, a file system can be implemented and work in real mode, but it will have some limitations caused by real mode itself.


For the most basic setup, you need to implement:
1) functions to read/write raw sectors (using BIOS int 0x13)
2) file system functions that use those in part 1

First learn what a file system is
http://en.wikipedia.org/wiki/File_system

and take a look at MiniDOS

oh gee, thanks i will look at those links

You can't expect too much. People here have limited time and explaining in detail the things you ask is very time consuming. Please try to receive links also as part of the deal. Often the links can give very detailed and relevant answers to your questions and allows the responders to give you the info you want without spending hours of their own time to say exactly the same things without links.

oh sorry, i did not see this response.
