We have an SST NANDrive chip on our board that supports the simple ATA command set. What's the easiest way to get support for this into our kernel so we can partition and mount the device? Using "da" and "umass" isn't really an option, since it is neither SCSI, nor attached to USB. Pulling in all of "ata" seems like overkill; all we really need is read/write block and some simple sense commands. They are all synchronous, it's low traffic and we are more concerned with simplicity than performance. Is there some subset of "ata" I can use that won't involve pci bus, controllers, etc? We just want to be able to write the LBA, SECT_CNT, and GO command and read the data. -- Andrew Duane Juniper Networks 978-589-0551 10 Technology Park Dr aduane@juniper.net Westford, MA 01886-3418 =20
