@kindex -displacment compensate altered image start address
@cindex Session, altered start address, -displacement
Compensate an eventual displacement of the image versus the start address
for which the image was prepared. This affects only loading of ISO images
and reading of their files.
Examples:
@*
If a track of a CD starts at block 123456 and gets copied to a disk file
where it begins at block 0, then this copy can be loaded with
-displacement -123456.
@*
If an ISO image was written onto a partition with offset of 640000 blocks of
512 bytes, then it can be loaded from the base device by -displacement 160000.
@*
In both cases, the ISO sessions should be self contained, i.e. not add-on
sessions to an ISO image outside their track resp. partition.
