I'm trying to get DosBox to work with a dos/windows cdrom of Sid Mier's Colonization. My problem is mounting the cdrom. In Windows I'd tell it the drive letter, but Mac OS X doesn't use drive letters.

Using DosBox Launcher I could mount the cdrom, but then it asks me what directory I want to install the software to, and nothing I put in works since I only have a cdrom mounted and no destination drive mounted.

Egads!!! Any suggestions?
