Need help with retrieving data from a DOS 2.11 formated floppy disk

Hi everyone: I need help to solve a problem. Could anyone lends a hand? The company I work for has a machine that runs on DOS 2.11 There are some data on that machine that we need to retrieve. The information is transfered from that old machine to a 1.44mb floppy. When we put the floppy into our pentium winNT4 computer , we can not read the information on the floppy. The NT os simply says it does not know what format the files are at. Now do I need to install a dos 2.11 or is there anyway around it ? What is the format the dos2.11 writing its files in? Are there any program that reads in that type of format? Does any one here have DOS 2.11 that I can download? Even if I do have DOS 2.11, will I be able to install it or do I need very old hardware as well? Jimmy Tsai SFU engineering 3rd year
