ReBar modded bios with Runtime module patches. Paddings are preserved.
I used a method from 2014. It was proposed for phoenix legacy bios mods to deal with insufficent space to manipulate modules.
The problem with paddings occurs when one or another module changes in size. UEFI compression can be compared to the way .png images are compressed. A sequence of FF FF FF FF is much easier to compress than 01 02 03 04. If we can’t grow or duplicate paddings in order to achieve proper alignment, why not to edit the module?
