I just learn about boot sector but, this code doesnt compiles after i changed JNE and JE instructions .....
Help me i dont know may be it compillers bug or something because everythinng worked befor i changed those 2 lines.

1. Please use [code] tags around your code. That puts it into scrollable window, and so your post with long takes less space. Also, your code gets colorized and spaces aren't ignored.

2. You posted in wrong section of forum. "Compiler internals" is supposed to be about compiler internals, this thread is now moved to OS development section.

Hi! that's complie OK in my Conputer.
je <-> jz
jne <-> jnz

2. He's asking about a compiler generated error message.

The error is caused by another process has exclusive write permissions, blocking Fasm from writing to the file.

you not open "boot.bin" at the same time???????????

Oooh, sorry.

Maybe your boot sector was executed somehow (as DOS .com file under Windows) and didn't exit properly. Hit CTRL+ALT+DEL, start Task Manager, and look if you can't find it as running process. If you find it, kill it.

I noticed that you have a lot of bugs. First off, you need to optimize your printing routine

I'm not sure what you're trying to do with the input as all you are doing is converting ascii to decimal and back. Anyways, it's still ridden with bugs. Here is a better way to do it

I based this code off what you have already have done so if it doesn't do what you intended it's not my fault. One last thing, end your code with the following

instead of

Also dont forget to select the display page with BH = page index.
