It would be worth suggesting here
D.O.G for DOSBox
awesome configurating package, you create a game profile, and in the profile you configure memories / irq's / sound cards / graphics cards / directorys etc... amazing bit of kit!
seems to have an issue with DOSBox 0.73 but I managed to get it to work using one of the Live D.O.G. Beta Candidates

it would be an absolute loss if you didn't try it.... (its free
)
