This device is essentially a small processor that sits on the PCI bus as a device and has access to a private ATA host adapter. It can act on the PCI bus as a sort of proxy for the ATA host adapter, but it doesn't do that very seamlessly. I hacked it into the FreeBSD 4.10 ATA driver by defining its PCI vendor and device IDs and got it to do non-DMA I/O with an ancient hard disk that did not support DMA. When I connected it to a modern CD drive that did support DMA (no modern hard drive was available), it locked up. There were other glitches. I eventually gave up. I exchanged some email with a Mark Lu at ITE who was working on a FreeBSD driver that plugged into the SCSI CAM subsystem. If you feel ambitious, you might try to contact him at Mark.Lu@ite.com.tw. He was able to give me a technical document describing parts of the PCI interface to the ITE 8212. (Unfortunately it left far to much undescribed.) Dan Strick
