ATA device numbering (that is to say, the X of an "adX" device) has always been a little odd in my experiences. Turning on or off a ATA interface (PATA or SATA) seems to adjust the numbering, regardless of ATA_STATIC_ID or not. It's likely that I do not understand what the kernel option does. > > 1) Have you verified that the SATA150-limiting jumper on your Seagate > > drive has been removed?

I didn't see any jumpers when I installed it The jumper is very tiny, usually gray, and on the back of the drive next to the SATA interface port. It's documented both on the drive itself, and in the product manual for the Barracuda 7200.10 -- see Section 3.2: http://www.seagate.com/staticfiles/support/disc/manuals/desktop/Barracuda%207200.10/100402371h.pdf The default (SATA150) is chosen because of known issues with SATA300 on older nForce chipsets. Seagate chose to limit the drives to SATA150 via a jumper, so that they would work on all machines, regardless of buggy or incompatible chipsets. > > 2) Do you happen to be using a PATA-to-SATA adapter on the DVD drive? > > > > It is native SATA (300) > > 3) If No to #2, are you sure that the ICH9 does SATA300 with ATAPI > > devices?

My motherboard also has SATA ATAPI support -- but my DVD drives are SATA150. I have never seen a SATA300 ATAPI drive. Now, that said -- I *have* seen Fujitsu hard disks which claimed to be SATA300 capable but weren't. It turned out to be false advertising; the SATA chip they used on their drives did not support SATA300, yet their product manual and ads said it did. This may be the case with your DVD drive as well. I would not put it past a manufacturer to put incorrect information in their product specs. Also, you do realise that having a SATA150 drive on your SATA bus does not mean that the entire bus runs at 150MB/sec, correct? It's not like SCSI. So there should be no performance hit having a single SATA150 drive on SATA controller also filled with SATA300 devices. In the future, take proper time to thoroughly read about the hardware you purchase, or at a bare minimum, read the labels manufacturers put on their products. :-) However: your PATA ports becoming unusable/disabled when you enable SATA in the BIOS could be either a BIOS bug (or "feature") or a FreeBSD bug. I would not put it past Gigabyte to have a BIOS bug (they are very well-known for having such, but are also pretty good about fixing such problems). Have you tried a BIOS upgrade on your P35 since you got it, or looked at the BIOS changelog? I do not have an ICH9 board to help confirm or deny -- I can purchase one if needed, and/or send it to Xin Li free of cost. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
