Did you check this video on mounting?
also,
If you are having an issue starting the game because you get an error saying the wrong CD is inserted:Solution: Go to the BFME2 installation folder (Program Files\Electronic Arts\The Battle for Middle-earth™ II) Right click lotrbfme2.exe, Properties -> compatibility -> Change Settings for all users -> tick out the compatibility mode.
I feel quite stupid now.
I totally overlooked the SCSI mount.
It works now thank you!
Sorry for all the trouble I've caused you.
