It's SCSI U320, not SATA. There is no (S)ATA on the motherboard at all.

By the way, thinking a bit more about what you said earlier about host raid. I am now certain it isn't host raid because it works by utilising the on-board AIC-7902 chip (adding the card switches out the 7902 BIOS and replaces it with the 2010 I2O bios). The 7902 bios already supports host raid so there would be no point at in in the 2010 also working via host raid.

According to the datasheet, it's based on an "Adaptec AIC-7930W microprocessor with hardware XOR". Is the 7930 supported at all ? Maybe that's the problem - I didn't think it would matter if it was I2O. Yes / No ?

I will try again with what you have suggested and report back. Thanks for the pointers.

I still don't understand though - why does it still use the aac driver if it's an I2O device ? Does the aac driver provide some glue or something ?

Thank you - I seem to be a bit short on that of late.
