DOS/4GW was a limited version of DOS/4G. Early versions had trouble with secondary DMA channels on the ISA bus (wreaking havoc with certain 16 bit soundcards). The 4GW version especially was also considered slow and bloated, and allows only up to 64MB of memory to be used. DOS/32A allowed allocation of up to 2GB, and has better performance and a smaller binary.
