Thus, my transfers are very slow (both the >"goal" and "current" are listed as 3.30 MB/s according to >/proc/scsi/aic7xxx/0). What about the user settings? If the user settings are higher than the goal, then the driver determined from inquiry data that the device is not capable of faster rates. The driver will never allow a target initiated transfer negotiation to exceed the goal rate. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
