NASM

The Netwide Assembler (NASM) is an open source, multi-platform 80x86 and x86-64 assembler that mostly follows Intel assembler syntax. It supports a range of object file formats including Linux a.out and ELF, COFF, LX, Microsoft 16-bit OBJ and Win32.

It contains some quirks relative to other OS/2 assemblers, or any assemblers on any other platform for that matter. Also available in versions for DOS, MacOS X, Linux x86 and MS Windows. There have also been a number of forks of NASM through the years, most notably YASM but most of them drop support for old Microsoft and IBM assembly formats.
