The 430NX Neptune chipset uses the SIO southbridge which does not have an integrated IDE controller. Most mainboards did not had an additional controller onboard, f.e. GA-586IP.
The 430FX66 uses the PIIX3s first revision FB.

- True about Neptune. But the chipset was sometimes paired with the buggy CMD640 IDE controller. Swaaye (talk) 06:59, 1 March 2013 (EST)
