I think this may be wrong. My Fujitsu M2952Q ultra wide drive works perfectly in ultra wide mode at ID=0. It was set to ID=15 when it arrived but I just removed the address four jumpers to set it to ID=0. This is what I get at boot-up (OK, I know it's not FreeBSD!), confirming that it's operating on ID=0 at 20.0 MHz (ultra) with 16-bit (wide) transfers: | scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 3.4/3.2/3.1 | scsi : 1 host. | scsi0: Scanning channel A for devices. | scsi0: Received MSG_WDTR, Target 0, channel A needwdtr(0xffff). | scsi0: Target 0, channel A, using 16 bit transfers. | scsi0: Target 0, channel A, now synchronous at 20.0MHz, offset 8. | Vendor: FUJITSU Model: M2952Q-512 Rev: 0124 | Type: Direct-Access ANSI SCSI revision: 02 | Detected scsi disk sda at scsi0, channel 0, id 0, lun 0 | scsi : detected 1 SCSI disk total. | SCSI device sda: hdwr sector= 512 bytes. Sectors= 4693462 [2291 MB] [2.3 GB] I would be surprised if the M2915Q behaved in a different way, unless there's something up with the driver for the NCR825. -- John Phillips john@linux.demon.co.uk
