Hi guys

I have a problem with cdrom mount under dosbox.
I would like to access the CDROM (mount dir or ISO file) after booting from .img file of HDisk where DOS6.22 is installed.
I installed the MSCDEX driver with the correct configurations in the autoexec.bat and congig.sys files.

Here are the rows of the dosbox conf file, but after booting if I write d: I receive the error message; "invalid unit specification"

# mount hard-drive
imgmount 2 "C:\HardDiskImage\Dos6.22-eng.img" -size 512,63,16,507 -fs none

# mount ISO DOESENT WORKS
# imgmount d "C:\myDir\myISO.iso" -t iso

# mount CDROM from real cdrom drive DOESENT WORKS
# mount D D:\ -t cdrom

# boot from harddrive c
boot -l c

Help me thanks
