DFI nf4: SATA drive won't show up in bios ???

[ryoanji]

I just moved from A8N-SLI to DFI nf4 Ultra-D. Everything posted fine, but for some unexplicable reasons I cannot find any of my SATA drives in bios. They are just not there. Niether two raptors nor 250G diamondmax 10. However, I do not have this problem with my Plextor DVD-RW and WD IDE drives.

Tried flashing to 3/10 bios, using different cables, clearing cmos a dozen of times, loaded optimized defaults, tried different SATA ports, tried booting with all 4 power connectors in. Nothing.

All SATA drives worked perfectly on A8N. What could it be?

Thanks a lot
