I am trying to mount an .img file (rootfs.img) so I can modify the features of the firmware for a derivitive of the 4fff N618 (Pandigital Novel).
I have flashed it with the firmware of the bqAvant and it is fully operational, but I cannot find a way to do a loopback mount with OSX 10.5, neither do I have a cd with a linux distro. The efi won't even let me boot from a usb device using rEFIt.
Using:
mount -o loop rootfs.img /mnt/rootfs
replies that loop is not supported.

You can mount a CD image without having to burn an actual CD or manipulate a floppy boot image. Of course, different platforms call it different things and use different tools. Mounting file images on Linux uses the loop device and is called a loop mount or a loopback mount.
A loopback device is a device that can be used as a block device to access files. The loopback file can contain an ISO image, a disk image, a file system, or a logical volume image.
Look here https://serverfault.com/questions/174909/mount-block-file-on-osx. Here are the correct parameters for hdiutil:
$ hdiutil attach -imagekey diskimage-class=CRawDiskImage -nomount <filename>
Example:
$ hdiutil attach -imagekey diskimage-class=CRawDiskImage -nomount /Users/me/backup.rdisk4s2.dd
Example Output:
/dev/disk6
