Or a Forth script in the > firmware... hmm.. that sounds pretty easy actually. The programming interface. http://t13.org/Documents/UploadedDocuments/project/d1510r1-Host-Adapter.pdf explains it all. The only other gotcha is that if you want to change the class bits to indicate the device is in legacy mode you must do that in an "early" fixup so that it occurs before pci_setup_device makes decisions based upon the programming interface. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
