/ALIGN (Section Alignment)
The /ALIGN option specifies the alignment of each section within the linear address space of the program. The number argument is in bytes and must be a power of two. The default is 4K (4096). The linker issues a warning if the alignment produces an invalid image.
Unless you are writing an application such as a device driver, you should not need to modify the alignment.
It is possible to modify the alignment of a particular section with the align parameter to the /SECTION option.
The alignment value that you specify cannot be smaller than the largest section alignment.
