3.2.3 Bootable information
|
||||
--------------------------
|
||||
|
||||
[TODO]
|
||||
- Addition of a boot image to a volume.
|
||||
- In most cases, the catalog and the boot image itself is added to the
|
||||
iso tree.
|
||||
- Alternatively, user can select to add a hidden images, i.e., images
|
||||
that don't appear in the iso tree.
|
||||
- Modification of boot image attributes:
|
||||
- bootable flag
|
||||
- load segment
|
||||
- load size
|
||||
- Automatic patching of isolinux images. User needs to set whether to apply
|
||||
this.
|
||||
- Reading of El-Torito info from multisession images. Modification of its
|
||||
attributes.
|
||||
- Removing of El-Torito images
