I suppose LINT is out of date in that respect. The best place to look to see if something is supported is in the actual driver. In this case it would be src/sys/pci/ahc_pci.c. (That's the PCI attach code for the ahc driver.) > The only reference line, points me: > > # The `ahc' device provides support for the Adaptec 29/3940(U)(W) > # and motherboard based AIC7870/AIC7880 adapters. > > So, which kernel device(s)/options should i enable to use adaptec > 3950U2W You should use the 'ahc' device for support for the 3950U2W. > 2) > > Does any body here use 3960U2W ? Does it runs well? > Which hard disks delivers 160Mb/s on U2 interface? Adaptec's web page doesn't mention a 3960U2W, although it does mention a 39160 card. In any case, none of the Adaptec Ultra160 boards are supported by 3.4. They are currently only supported in FreeBSD-current, although I expect that support will be merged into -stable before too long. Also, at the moment, the Ultra160 boards will only run at Ultra2 speeds. That should also change before too long. > 3) > If adaptec 3950U2W is not supported by FreeBSD 3.4Stable, i am > considering using 2940U2W. Both the 3950U2W and 2940U2W are supported in 3.4, and 3.4-stable. > I would like to hear from you, what options on hard disk i have (Ones > that delivers 80MB/s) and how success you have gotten using them. If you're looking for disks, I would recommend high end IBM and Seagate drives. i.e., the Seagate Barracuda and Cheetah drives, and IBM Ultrastar drives.
