TThe 62 MB limit mentioned in boot.rst is unrelated, and only applies to very, very old kernels that used INT 15h, AH=88h to probe memory.


I am 88% sure this was fixed long before setup_data was created, as it was created originally to carry e820 info for more than 128(!) memory segments. However, as we see here, it is never certain that bugs didn't creep in in the meantime...
