Short answer: you can't. Use DOSBox.

Long answer: The XNU kernel (the one used by Mac OS X) doesn't support
virtual-8086 mode, which is needed for Wine to be able to run DOS
executables. It might be possible to add this support, but Apple will
never get to that anytime soon.

Another possibility is to integrate support for DOSBox straight into
Wine. This has been discussed on wine-devel, but to date no one has
implemented it.
