DosBox is meant for games, other than that, I assume you mean .diff patches, you need to patch the source and compile it.

Thanks for the reply.

I'm hoping to use DosBox to get my old, automated Lotus 3.4 spreadsheets running for business, until I can program either Excel or OpenOffice to replace them. And it would make a big difference if I could get Ctrl-Break to work.

Nikolay Nikolov's webpage for his Ctrl-Break fix is:

http://sourceforge.net/tracker/?func=detail&a … 551&atid=467234

And the two downloaded files from that page are:

dosbox-bios-ctrlbreak-v2.patch
dosbox-bios-ctrlbreak-v3.patch

Windows doesn't know how to open them, and the Copy/Paste suggestion on Yahoo! Answers India didn't seem to work, either.

Does anyone know how to install the above two patches?

Thanks again for any help!

Patches are text files that you will need a patch or diff program (command line progranm) to apply it to the source of dosbox and the you will need to COMPILE dosbox yourself.

As I already said...those patches need to be applied to the source...Windows will never know how to open them unless you install something that handles diff patches like...say...TortoiseSVN; after succesfully patching the DosBox sources you will need to compile it into an executable program using MinGW, Visual C++ or some other compiler, so, in other words if you want to "install" them or open them with DosBox or have something magically precompiled...you're SOL; unless you find some giving soul willing to devote the time to patch the sources and compile the thing(s, as DosBox needs several libraries) for you.
Maybe read this...

Got it .. will get to work on that, and will let the forum know how it worked.
