I actually discovered another thing that might have added to my problems.

It seams that the long list of options under: [Serial ATA (prod) and Parallel ATA (experimental) drivers] ---> [ATA SFF support] dissapears when I disable the [Bus option] --> [PCI support]. I didn't think that the SATA drivers actually should be affected by this. Seams that I shuld do my homework in PC-architecture.

Bye felleas, think its time to close this case.
