Adds the ability to use the FMS image size greater than 2.1Gb. This
limitation is due to the maximum number of available frames on the
CD-ROM media.
An incoming implementation of additional media formats (DVD-ROM, BD-ROM)
should support both formats' possible capacity.
End-user-impact: Now, the FMS able to use a medium-image backend file,
which size is more significant than 2.1Gb
