[Solved] Sata 1 - atapi incompatible

i have 2 sata wd 500 mb set up in raid 0 and a sata optical drive attached to my asus p6t v2 deluxe.
its a brand new build btw. Anyways on post it says "sata 1 - atapi incompatible press f1 to resume"
however i have nothing connected to sata 1 slot. any ideas would help thanks.

I think the error message you see is generated by the early boot process of the Operating system trying to load (probably Windows). Windows has certain drivers "built in" to be able to use devices without external add-on drivers, and a way to handle ATAPI devices is among those. That way you can set your system to boot from an optical device as long as it conforms to the ATAPI standard. It looks like Windows went to the SATA_1 port expecting to find there an ATAPI-compliant device to try booting from, but failed to find such a thing. So it is telling you what it "found" was not ATAPI-compliant. It is alerting you and offering its standard alternative. You press the "F1" key and it will continue, probably by abandoning its try on SATA_1 and proceeding to the next possible device in your Boot Priority Sequence.

Check the Boot Priority Sequence in your BIOS Setup screens. Does it include trying to use something on SATA_1? Maybe you can fix this in two stages. First, set the Boot Priority to use only your HDD, and no later options. Save and boot from there. Then reboot into BIOS Setup and set your sequence again, this time inserting your real optical drive, wherever it is, before the HDD. Save and boot that way. See if that gets rid of your problem.
