Hi guys! 😀

I need to write some .asm code for school. Unfortunately I am running OS X Lion so I can't test if it works. I found DOSBox to be the best solution.

I downloaded necessary files here

http://dl.dropbox.com/u/5593269/aio2011.zip

I moved these files to my desired location.

Then I ran DOSBOx.

Then I "wrote mount c ~/Documents/School/IAS/allinone2011/"

Folder was mounted successfully.

Then I tried "run hello" but it didn't work. Can you tell me guys what am I doing wrong?

You're not doing anything wrong per se, but your package is missing something, so not quite "all-in-one". The linker you're using requires the Microsoft DOSXNT MS-DOS Extender when running in plain DOS (and DOSBox), which it doesn't need when running under the Windows Command Shell. You should be able to find a DOSXNT.EXE that works with a Google search.

Hi ryowa,

Not sure what you mean with 'it doesn't work'. When I try, I get an error message as shown below, about a missing DOSXNT.EXE. I think your school should provide the full ASM package, although this file can also be found here.

Thanks guys! 😀

@rcblanke yes, I am sorry. By 'it doesn't work' I meant I couldn't use command 'run'. It said 'Illegal command: run.'

But thanks to your picture I realized that I mounted C but i didn't moved into the folder using C:

Thanks again for your help. I am sorry for this unnecessary topic.

edit: First time using DOSBox 😒
