I assume "geometry" is this in isohybrid.in
# Use this fake geometry (zipdrive-style...)
$h = 64; $s = 32;
It would influence
$psize = $c*$h*$s;
$ehead = $h-1;
$esect = $s + ((($cc-1) & 0x300) >> 2);
$ecyl = ($cc-1) & 0xff;
Again my non-expert questions:
- Can it do harm ?
(What parameter combinations are ok ?)
- What is it good for ?
(How to describe this in libisofs API and in
xorriso man page ?)
- Does it influence the need for 1 MB image
size alignment ?
Have a nice day :)
Thomas
