Maybe you need some parameters more when mounting cd-rom like supplying a valid label or input-output control.

E.G. mount d d:\ -t cdrom -label 7thg -ioctl -usecd 0

Type mount -cd to see some options.

You should try the CVS, some CD fixes have been implemented. Not sure where your going to find a precompiled OSX binary tho.

you might have to supply a label

try "intro cdrom" inside dosbox

Well, I've found that I can get the farthest with mounting /Volumes/cdblah with no flags. (It's a symbolic link (I think) to the mounted cd drive that acts as a directory on your hard drive and not a cd) It will at least launch things from the cd and spin up and read the cd. It inevitably freezes up at some point, but that might just be my extremely scratched cd.

I have this exact same problem with 7th Guest and I haven't figured out how to get around it. Anybody got a definitive answer as to why you can access the CD to run the install, but then get a message saying that the CD is not loaded?

Same problem with 7th Guest.

Dosbox cdrom support seems still a bit weak. I wanted to get The 7th Guest working with Dosbox. I also wanted to play Fantasy General for DOS and be able to hear the CD Audio. So far no luck. I am using Ubuntu Linux 5.04.

I did intro cdrom in Dosbox and tried the best mount command I could come up with:
mount d /cdrom -t cdrom -label T7G_DISC2 -usecd 0 -ioctl
I run D:\INSTALL.BAT and it says that "The second disk of The 7th Guest is not in my CD-ROM drive..."

The second idea I had was to setup cdrom support in config.sys and autoexec.bat. I found autoexec.bat section in my .dosboxrc, but I have no clue where is the config.sys? I would throw in something like:
[config.sys]
DEVICE=C:\CDROM.SYS /D:123
[autoexec.bat]
C:\MSCDEX.EXE /D:123

I also tried to use an old dos program called FAKECD. When I tried to use it, FAKECD said that I need to increase number of drive letters in config.sys. Well, since I don't know where is the config.sys in dosbox, I did not know what to do. I tried "SET LASTDRIVE=Z" with no luck.

Bottom line:
1) original 7th guest cd says there is no install disk in my cdrom drive.
2) I do not hear CD Audio playing with original Fantasy General CD.

banasw01: for reference, what version of DOSBox are you using and under which OS? You might try a recent CVS build (see the development forum), as numerous CD-ROM and filesystem fixes have been made since 0.63 (the latest official version).

Also, DOSBox doesn't have any native support for config.sys stuff. There are tools that let you load .sys drivers from the DOS prompt, or you can install a real copy of DOS inside of DOSBox to get config.sys support.

Sounds good, I will try the newest CVS build.

I am using Ubuntu Linux 5.04 and Dosbox 0.63.
I might try to install MS-DOS if I can find my old disks 😜

This may be fixed in CVS as mentioned above. I did get around this problem in 0.63 using a couple tricks. I think the problem has to do with the program/batch files changing the working directory but I could be wrong.

Anyway, I have my cdrom mounted pretty much the standard way:

mount d /cdrom -t cdrom -usecd 0 ioctl

I see the problem if I just run the install.bat file on the root of the cd. If I change into the actual install directory and run the install.exe with the cdrom drive letter as an argument the install goes through.

d:
cd t7g\install
install d:

The install goes through but hung on me for the last file (xmi.rl I believe). I checked the install directory and all the files including the last one seem to be there and the correct sizes. When you try and run the game you get the same kind of error, asking for disc one even though it is in there. I found to get around this you must first make sure you are in the root of the cdrom, and then run the v.exe program in the install directory.

d:
c:\id\t7g\v !

Using this way the game starts up and seems to play fine. The big unknown in this method right now is what will happen when disc 2 is needed. I guess I will have to play through it now to find out. But this may be a good workaround for people too lazy to install CVS.
