The 2nd chip isnt just for decoration Its actually there so that the dbox overheats more and causes more sticking and freezing problems for us users... without those, a dbox just wouldnt be the same
On a box with 1x flash chip the intel flash chip hold 8 megs datas and on a box with 2x flash chip each flash chip holds 4 megs datas. The sum is the same, 8 meg flash memory.
