Get the os from here:

Unzip the two files MPC2000.EXE and MPC2000.ZIP. Copy them onto a floppy disk that is FAT formatted. Be sure they are the only two files on that floppy.
Boot and enjoy.
BTW, I found this information in one minute by doing a search of this forum. You might want to try that next time.
