The chipset probably handles 2 diskettes just fine, as does the BIOS.
What's probably missing are the traces to connect the chipset to the
connector. As Ray will tell you laying out complex boards with lots of
interconnects is hard. Fewer traces makes it easier. There's also the
costs savings of less copper and gold per board. It's not much for one
board, but when you are working in the millions the difference is
significant.
