\fB\-load\fR entity id
Load a particular (possibly outdated) ISO image from a -dev or -indev which
hosts more than one session. Usually all available sessions are shown with
option -toc.
.br
entity depicts the kind of addressing. id depicts the particular
address. The following entities are defined:
.br
"auto" with any id addresses the last session in -toc. This is the default.
.br
"session" with id being a number as of a line "ISO session", column "Idx".
.br
"track" with id being a number as of a line "ISO track", column "Idx".
.br
"lba" or "sbsector" with a number as of a line "ISO ...", column "sbsector".
.br
"volid" with a text as of a line "ISO ...", column "Volume Id".
.br
Adressing a non-existing entity or one which does not represent an ISO
image will either abandon -indev or at least lead to a blank image.
.br
If an input drive is set at the moment when -load is executed, then the
addressed ISO image is loaded immediately. Else, the setting will be pending
until the next -dev or -indev. After the image has been loaded once, the
setting is valid for -rollback until next -dev or -indev, where it
will be reset to "auto".
