please add the directives SectionAligment and FileAligment for FORMAT PE

What do you need non-standard section and file alignment for?

Is there a reason for doing this? What is wrong with the current settings?

If you just want to experiment with different values you can search this forum for any of the various custom PE generators already posted here.

I modify the source code fasm, but would like to have them in standard assembly

Moved to "Compiler Internals"

Yeah, but what for?

I am sure you realize how many similar options are there, that someone might sometime want to experiment with. That would overload FASM with zounds options barely ever used, pretty much conflicting with its minimalistic design. Unless there is a real-world reason for supporting such option, I don't see it coming.

VID, didn't any of those EFI drivers / executables you looked at a while back use 32byte section and file alignment?

Most of the ones I've looked at seem to although it doesn't stop there. There is in some cases Terse Executable headers (TE) too (a cut down PE format MZ-->VZ).

But I would have to say for the number of times I've used it, it is fairly quick and easy just to change FASM source and have a separate compiled FASM for EFI so can very well understand and agree with your comment.

I'm not really sure, it is quite possible for Pre-EFI (PEI) modules. Those were mostly TEs (Terse Executable format that you mentioned), but not exclusively. My guess would be TEs ignore these alignments completely, but there were several "full blown" PEs in PEI last time I checked, where they probably too strived to save precious bytes. We'd need to check all that. If true, this would be a good point, even though still quite a minor one.
