Mentore 2007-09-05 06:03:23 UTC "Not to note that DOSBox has a complete sound blaster emulation, while the Dos virtual Machine on OS/2 relies on OS/2 drivers and VDD - not always available, until Martin Kiewitz (heil, heil) completes his VSOUND." Peter Brown, 2007-09-05 10:56:27 UTC "I have a mainboard with an nForce CK804/ALC850 sound/mixer chipset which uses the uniaud driver for sound in eCS. There is no DOS support in uniaud but DOSBox provides a choice of Soundblaster or Gravis UltraSound emulation which works fairly well for a lot of games that have either of those cards in their setup list."
