My understanding is that "syslinux.efi" should work on devices with 4k 
bytes per sector on a FAT volume recognized as the ESP on a GPT scheme.

Using tools, for partitioning and for formatting, that also support 4K 
devices should also be a factor.

I would like to assume that "all" UEFI firmware correctly supports 
booting to such "4k" devices, but any assumption about UEFI 
implementations might be too much to expect in some cases.

I am not sure how/what "virtual" devices can actually be used as "4k" 
storage.

My _*guess*_ is that no developer of Syslinux has actually tested this 
scenario (i.e. booting syslinux.efi on "4k" devices), but I could be 
wrong.

Ady.
