I am having the same problem with the same game. I have read the README and the FAQ's and newbie posts. The problem is the same, it won't recognize the CD and comments "Unable to locate the Advanced Civilization CD."
I have tried all of the following, after mounting C:
mount d d:\ -t cdrom
mount d d:\ -t cdrom -ioctl
mount d d:\ -t cdrom -ioctl -usecd 0 [after having performed "mount -cd" to find out it is 0]
and, all of the respective combinations of order. The only combination that causes the cd to spool up is the latter, but the same error occurs of "Unable to locate ...".
I have tried to copy the entire contents to the HD and then mount the directory I copied the cd to as the cdrom directory.
All of the previous work were on Win2k and Win XP machines. On the XP machine, I also tried to load the game and utilize the right-click->properties->compatibility->open as Win95 option to the same issue.
I saw the game on the list of supported, but for whatever reason I am not able to get it working. Any ideas would be appreciated.
Thanks,
