You have several "int 0x21" calls in your code. These are DOS calls: [url]http://www.ctyme.com/intr/int-21.htm[/url] Since DOS is not loaded (indeed, you are writing your own OS), then you cannot use these functions. You must restrict yourself to just the BIOS calls. Nathan.

Your best bet would probably be to look at existing (hopefully *working*) example code which you can find stored away all over the Internet.

If you insist on learning the obsolete DOS-style 16-bit code, then you need to get a 16-bit linker. One is available ( Lnk563.exe ) here: [url]http://website.masm32.com/microsft.htm[/url] Nathan.

[QUOTE=PieSquared;416853]I'm writing a compiler, but if I want it to be on more than one platform, it seems I have to learn every assembly language for the different platforms. I've seen a number of languages which try to be 'portable assembly languages' such as Linolium and C--, but they all …

Since Mac OS X is based on BSD, you will have better luck making BSD-style calls instead of those Linux syscalls. BSD looks for the function parameters on the stack instead of in the registers.
