    handbook: The freebsd-boot 512KB limit is for legacy BIOS
    
    A question[1] on Reddit asked about the 512KB freebsd-boot limit due to
    "current boot code limitations" in the context of EFI booting.  Be clear
    that this is aobut legacy BIOS booting.
    
    This section should have a larger rework for EFI, but this is at least
    an improvement for the existing text.

 Proper sector alignment provides the best performance, and making partition sizes even multiples of 4K bytes helps to ensure alignment on drives with either 512-byte or 4K-byte sectors.
 Generally, using partition sizes that are even multiples of 1M or 1G is the easiest way to make sure every partition starts at an even multiple of 4K.
