Actually, my 2514 has 2 slots and I have single 16mb PARTITION. When u do a sh ver, u'd see 2 8mb partitions, what you need to do is go into the configuration mode, and issue a router#(config)partition flash:1 16 command (check to see if your IOS supports the command). This will erase everything on the flash, or will ask you to wipe the contents of the flash, I can't remember now. In any case, that will give you a single 16MB partition.
