I have the same (maybe, mine is 7N2 Delta2 Platinum) motherboard as his
and it does has SATA support. Mine SATA is disabled in BIOS, which I don't
have any SATA HD.

=====================================
? nVIDIA nForce2 Gigabit MCP Chipset
- Integrated Ethernet MAC
- Integrated Hardware Sound Blaster/Direct Sound AC97 audio
- Ultra DMA 66/100/133 master mode PCI EIDE controller
- Supports USB 2.0
- Integrated SATA Interface
=====================================
