If you install the IBM MWave Dolphin sound/modem card using Add New Hardware/Other Devices/IBM, the basic drivers will be installed for the modem and sound card. However, MIDI can not be used until MIDI samples are installed. This file is the MIDIMED sample set which is what the basic install above looks for. So MIDI will sound awful until these MIDI samples are installed. Look in MWAVE.INI in C:\MWW for more info and the README.TXT in C:\MWAVE\SAMPLES\MIDIMED after installing this file. Good luck.
