Supervivi and Qtopia

What is the difference between Supervivi 128MB and 64MB?
Also,  What is the difference between Qtopia 2.2.0 128M+ and Qtopia 2.2.0
64M?

The 64M version is for boards with 64MB NAND flash and the 128M+ version is
for 128MB/256MB/1GB NAND flash.

how do i know that the NAND flash of my board is 64MB or 128MB?

Check the flash chip on your board.
