Technical Advisory TA-550-1 (Addendum)
				Utility Use Instructions
				April 26, 2002


The utilites mentioned in this instruction sheet are referenced in the SCB2 Technical Advisory TA550-1. They should only be used on SCB2 server boards that are suspect of having the issue described in the TA. SCB2 boards that are suspect will meet all of the following criteria:

- SCB2 (SCSI) Server boards
- SCB2 (SCSI) Server boards with the following PBA - A46044-607
- SCB2 (SCSI) Server boards that fall within the following range of serial numbers: KRC2209xxxxx - KRC2215xxxxx

Note: Not all of the SCB2 server boards that meet these criteria are affected by the issue described in TA550-1.  All the SCB2 (SCSI) Server Boards that are found to have the rev 7 ADM1026 sensor chip and show symptoms as described in the TA will meet all the above criteria.

If after using one of the system scan utilities you find that you have a board with the rev 7 ADM1026 sensor chip and it meets all of the above criteria, please refer back to the technical advisory for Intel recommendations.

-------------------------------------------------------------------------------------------------------------------

If a visual scan of the SCB2 Server Board is not immediately possible or is inconvenient, Intel has provided 3 utilities to help determine if an operational SCB2 Server Board is affected by the issue referenced in TA-550-1. 


Scan Utility #1) Hecver.exe: This is a DOS based utility to determine if a system is at risk. This is the recommended option, as it requires that no additional drivers or system manamgnet software be installed.

- Boot the system using a DOS boot disk (Not provided) or to the SCB2 Resource CDROM that came with your system. 
- At the DOS prompt type HECVER

---------------------------------------------------------------------

Scan Utility #2) Hecwin2k.exe: This file is a Self-extracting zip file which contains all the necessary files to scan your system run under the Microsoft* Windows2000 operating environment.  

- Copy this file to a temporary directory in windows (C:\HEC)
- Run this program to unzip the components. 
- Open a DOS window in that same directory (C:\HEC). 
- Type INSTALL to install the IMB driver (provided). This step is NOT needed if you are already running ISC on the system. 
- Type HECETAID to determine if the system is at risk. 
- When complete, simply delete the temporary directory C:\HEC.
----------------------------------------------------------------------

Scan Utility #3) HecetaID: This is a Red Hat* Linux 7.2 based utility. To run this scan utility, Intel Server Control (ISC) must be installed, or a compatible IMB driver must be installed. Information for creating a compatible IMB driver can be downloaded form the following Intel websites:

http://support.intel.com/support/motherboards/server/isc/linux.htm
http://www.intel.com/design/servers/ipmi/ipmi_driver.htm

- load the appropriate IMB driver
- type HECETAID

----------------------------------------------------------------------

For those SCB2 server boards found to have the rev 7 ADM1026 sensor chip and the server board meets the criteria described above, Intel recommends disabling the onboard thermal sensors if the server board is installed into an Intel SR1200 or SR2200 server chassis and is using Intel server managment. In this environment, no system thermal monitoring is lost, as the BMC controller uses the thermal sensor located on the system front panel board as the primary data source for system thermal monitoring.

TA550.exe: A DOS utility used to disable the onboard temperature sensors. 
- Boot the system using a DOS boot disk (Not provided) or to the SCB2 Resource CDROM that came with your system. 
- At the DOS prompt type TA550

Note 1: The Utility will disable the onboard thermal sensors if the SCB2 server board has a PBA number of A46044-607 and it has a rev 7 ADM1026 sensor chip installed. It will also disable the onboard thermal sensors if it is unable to determine either the boad PBA number or the revision of the ADM1026.

Note 2: This utility must be re-run if the system FRUSDR utility is run.  The FRUSDR utility will restore the factory defaults for all onboard sensors.
