First off make sure you've enabled Ultra speeds in the Adaptec's BIOS (ctrl-a at boot time when the message comes up), secondly make sure you're using ultra devices. Probing for devices on PCI bus 0: chip0: rev 0x03 on pci0.0.0 chip1: rev 0x01 on pci0.7.0 ahc0: rev 0x00 int a irq 11 on pci0.11.0 ahc0: aic7880 Wide Channel, SCSI Id=2, 16 SCBs ^^^^^^^^^^^^ This should probably be changed to identify ultra channels. The aic7880 and ahc2940UW are Ultra Wide controllers. scbus0 at ahc0 bus 0 sd1 at scbus0 target 0 lun 0 sd1: type 0 fixed SCSI 2 sd1: Direct-Access 3067MB (6281856 512 byte sectors) ^^^ This is a Ultra-Narrow drive. Speeds above 10mhz (I think) are Ultra speeds. The speed is shown if you boot -v sd0 at scbus0 target 1 lun 0 sd0: type 0 fixed SCSI 2 sd0: Direct-Access 699MB (1431760 512 byte sectors) cd0 at scbus0 target 4 lun 0 cd0: type 5 removable SCSI 2 cd0: CD-ROM can't get the size If you boot -v you'll see something like this for Ultra devices: ahc0: target 0 synchronous at 20.0MHz, offset = 0xf Linux: The Microsoft Windows(tm) of the Unix(tm) world. - alex
