My understanding about that jumper is that you DO NOT WANT THE JUMPER ON. Without the jumper, sector 0 is 4KB aligned, as is any sector multiple of 4. But WITH the jumper, sector 0 is no longer 4KB aligned.. everything shifts by one (or seven) such that sector 63 ends up being the start of a 4KB low-level sector, instead of the more sensible sector 64.
