Depends on your OS.
Android 2.x.x: "mount c /sdcard/DOSGames" (or "mount c /sdcard/external_sd/DOSGames" if you store your games on an external SD-card)
Not quite sure about Android 3 and 4; I know that ICS mounts the sd-card differently, but I didn't like ICS, so I went back to Gingerbread again after a few days. Something like "mount c /emmc/DOSGames" should do the trick.
Just download a free file manager like ES File explorer to see the mountings.
And I'd suggest you install the game through windows and copy all the stuff to your tablet afterwards. Just make sure you mount the same DOS directory (e.g. "mount c c:\tri" in Windows and "mount c /sdcard/tri" on your tablet).
