One: -f coff.
The NASM package also comes with working example assembler and C source code
for DJGPP. 
From the Nasm documentation NASM.DOC:

=======================================================================================
Running NASM
============

To assemble a file, you issue a command of the form

	nasm -f <format> <filename> [-o <output>]

For example,

	nasm -f elf myfile.asm

will assemble `myfile.asm' into an ELF object file `myfile.o'. And

	nasm -f bin myfile.asm -o myfile.com

will assemble `myfile.asm' into a raw binary program `myfile.com'.

To get usage instructions from NASM, try typing `nasm -h'. This will
also list the available output file formats, and what they are.


`coff' and `win32': Common Object File Format
---------------------------------------------

The `coff' format generates standard Unix COFF object files, which
can be fed to (for example) the DJGPP linker. Its default output
filename, like the other Unix formats, is `filename.o'.

The `win32' format generates Win32 (Windows 95 or Intel-platform
Windows NT) object files, which nominally use the COFF standard, but
in fact are not compatible. Its default output filename is
`filename.obj'.
