The title of this issue seems confusing. But I see the error message you highlight. Have you tried it in regular DOSBox?
Operation AirStorm
I think that Dosbox Daum fork has this feature
https://github.com/dosbox-staging/dosbox-staging/issues/2915
It looks like this game requires booting into real MS-DOS not being run from the DOSBox DOS environment to get that feature. Booting into DOS should be supported by this core, it just needs to be set up correctly. But when running from DOSBox DOS the error you have appears which I think is expected in all DOSBox variants.
