On my PC164, I have an ATTO SCSI interface, which I'm using with 
three SeaGate Ultra/Wide drives. It probes as follows:

siop0 at pci0 dev 9 function 0: Symbios Logic 53c875 (ultra-wide scsi)
siop0: using on-board RAM
siop0: interrupting at eb164 irq 3
scsibus1 at siop0: 16 targets, 8 luns per target
[...]
scsibus1: waiting 2 seconds for devices to settle...
siop0: target 0 using 16bit transfers
siop0: target 0 now synchronous at 20.0Mhz, offset 15
sd3 at scsibus1 target 0 lun 0: <SEAGATE, ST34371W, 0280> SCSI2 0/direct fixed
sd3: 4148 MB, 5168 cyl, 10 head, 164 sec, 512 bytes/sect x 8496960 sectors
siop0: target 1 using 16bit transfers
siop0: target 1 now synchronous at 20.0Mhz, offset 15
sd4 at scsibus1 target 1 lun 0: <SEAGATE, ST34371W, 0484> SCSI2 0/direct fixed
sd4: 4095 MB, 5172 cyl, 10 head, 162 sec, 512 bytes/sect x 8388314 sectors
siop0: target 2 using 16bit transfers
siop0: target 2 now synchronous at 20.0Mhz, offset 15
sd5 at scsibus1 target 2 lun 0: <SEAGATE, ST34371W, 0860> SCSI2 0/direct fixed
sd5: 4095 MB, 5899 cyl, 10 head, 142 sec, 512 bytes/sect x 8388315 sectors

I note that this looks very similar to the output from "ncr" but not 
quite. I wonder if the "ncr" driver is reporting MHz as MB/s when it 
should not.
