I have a Digital PWS 500au with an on board Qlogic 1040B Ultra Wide SCSI Controller. I used to have an IBM Fast wide SCSI hard drive that was correctly probed with the following message in dmesg. da0 at isp0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-2 device da0: 20.000MB/s transfers (10.000MHz, offset 8, 16 bit), Tagged Queueing Enabled I recently replaced this hard drive with a new Seagate ST336706LW - 36ES. I notice the following dmesg. da0 at isp0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-3 device da0: 20.000MB/s transfers (10.000MHz, offset 8, 16 bit), Tagged Queueing Enabled My question is: Why doesn't this drive operate at 40.000MB/s since it is backwards compatible with Ultra Wide SCSI? Do I need to set something up in the SRM before booting FreeBSD? Here is the SCSI controller detection lines from dmesg: isp0: port 0x8000-0x80ff mem 0x81080000-0x81080fff irq 3 at device 4.0 on pci1 isp0: interrupting at CIA irq 3 Thanks for your help. Chris.
