At least on the boards I checked this, the sensors give very inaccurate data - e.g. temperature accurate to 0.5degC. You can't really use that for random data. I guess Intel's RNG has many more digits. -- Didi ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
