I got most of the way thro' your instructions (including mounting d as c\games) but fell at the last hurdle "type cd dgate". It said "unable to change to dgate"
Anyway I foxed it. At the c prompt I typed D (colon) & it changed to D so then I could type cd dgate & then dgate AND THE GAME STARTED!
In DOSBox config, following the article I had mounted d as the cd rom drive but have now changed that to mount d c\games3 so it will always do that otherwise it had to be mounted every time
Bit worried about not having it reading the cd rom drive BUT thought if I made this separate folder c\games3 for deathgate, any games on cd rom could be loaded into there if they needed to be run from D. Don't know whether that makes sense.
Also, do you change the Sound config. in install.com? I changed it to SoundBlaster16 as in article. Have you found that the best for this game?
Anyway, thanks so much for your help, Sebatianos
