How to get disc based games working in DOSbox

[retronoobie3000]

I'm trying to get a couple old games working in DOSbox and I know that they were disk based originally. Each game is giving me the same message, that I need the driver to run the disc drive. The games are Ultima 7 complete, Ultima 8 Pagan, and Legend of Kyrandia Malcom's Revenge.
I've checked the compatibility list and both Ultimas are supposed to work just fine. Malcom's Revenge is not on the list but hopefully will work.
Anyone have any ideas, or maybe some config file configuration that might work? I'm a bit of a noobie, and while I'm learning how to configure these things, I have no idea how to get this driver thing working.

I'm running Retropie 4.3 on a Pi 3 B. DOSbox is updated as of yesterday.

Any help would be appreciated.

I assume you mean the games needs to find the disc in the drive to start, otherwise it won't work ? Check this recent topic on how to set-up a .conf file that will start the game and also mount an .iso image so it appears as a disc drive in dosbox.

@retronoobie3000 I know this does not help DosBox but malcolm's Revenge runs flawlessly in scummvm.
