I had a lot of problems with a ASUS M2N (also with MCP51 SATA). 
Particularly with oldish PCI cards scrambling the embedded devices' IRQ: 
try moving PCI cards to different slots, or booting without any PCI card.
I suppose you upgraded your BIOS to the latest version available? Also 
the setting about Plug-n-play OS is of course important.
