ok here's a part from the DOSbox helpfile on how to mount it:
Q: My CD-ROM doesn't work.
A: To mount your cdrom in DOSBox you have to specify some additional options
when mounting the cdrom.
To enable the most basic cdrom support:
- mount d f:\ -t cdrom
To enable low-level SDL-support:
- mount d f:\ -t cdrom -usecd 0
To enable low-level ioctl-support(win2k/xp/linux):
- mount d f:\ -t cdrom -usecd 0 -ioctl
To enable low-level aspi-support (win98 with aspi-layer installed):
- mount d f:\ -t cdrom -usecd 0 -apsi
In the commands: - d driveletter you in DOSBox
- f:\ location of cdrom on your PC.
- 0 The number of the cdrom drive, reported by mount -cd
