In this case, we are talking about a serial eeprom. I would not expect the values in the eeprom to change unless the user enters SCSI-Select again. Unfortunately, since I do not have a serial eeprom dump with the state of the eeprom before and after this change, I cannot determine exactly what was wrong initially. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
