in the [dos] section of the conf file, change xms to false and ems to true. xms is "extended" and ems is "expanded". Dumb hey. I used to be hired by people to get games workint for their kids, so I made these boot disks with multiple configs on them inc. mouse/no mouse/cd-rom/no cdrom/sound/no-sound etc. Years ago I was really enjoying playing Ultimate VII Part II - Serpent Isle which was really kooky with it's RAM requirements, then I upgraded to an SBLive soundcard and it didn't work cos the soundblaster driver was too big! Anyway over the years I kept trying to get it to work and failed then about 2 years ago got DOSbox and it finally worked again and I completed the game - lush! I was so happy.
