There is a 'builtin' method of mouting ISO images, but sadly not BIN/CUE images.
In order to mount an ISO image of a data disc, you need to...
(enter root's password)
#mount /path/to/isofile.iso -o loop /path/to/mountpoint
For me, that would consist of something like:
#mount Mandrake-9.1.disc1.iso -o loop /mnt/iso
Do not forget, however, that when umounting it to use the -d option:
umount -d /path/to/mountpoint
This way you free up the /dev/loopX devices aswell.
