That's megabit, not megabyte ;) so 32mbit would make 4 megabyte.
That chip is connected to the mainboard's remote management features.

No, there most likely are subtle differences like page/sector size,
environment friendlyness, etcetera.

This is where you subject the flash chip to a visual exam.

Here, the flash chip is located to the right of the middle PCI slot.
