The table is located in the block immediately following the Superblock. So if the block size (determined from a field in the superblock) is 1024 bytes per block, the Block Group Descriptor Table will begin at block 2. For any other block size, it will begin at block 1. Remember that blocks are numbered starting at 0, and that block numbers don't usually correspond to physical block addresses.
