4TiB?!

The article [A] that's referenced by the "[2]" right after "2^32*512 +
2^32*512" doesn't mention 4GiB and it later says "Therefore, the
maximum disk size supported on disks using 512-byte sectors (whether
real or emulated) by the MBR partitioning scheme (without using
non-standard methods) is limited to 2 TiB."

"non-standard methods"?
