Build Stamp : ME Firmware             --> 02.01.05.069
              ME Recovery Boot Loader --> 02.01.05.069

                        ME RECOVERY INSTRUCTIONS
================================================================================
The Recovery process can be initiated by setting the recovery jumper (called ME
FRC UPDT Jumper)

The following steps demonstrate this recovery process:
   1.  Power OFF the system.
   2.  Switch the ME FRC UPDT jumper. Details regarding the jumper ID and
       location can be obtained from the Board EPS for that Platform.
   4.  Power ON the system.
   5.  Enter Setup and verify Error manager displays 83A0 error code
   6.  Boot to EfiShell and update ME if necessary
   7.  AC OFF the system, and revert the ME FRC UPDT jumper position to
       "normal operation".
   8.  Power ON the system.
   9.  Enter setup and verify Error Manager does not display 83A0 error code

Note 1 : ME will continuously monitor recovery jumper. Whenever ME FRC UPDT is
         asserted ME will immediately switch to recovery mode.  AC Power cycle
         is required after de-asserting ME FRC UPDT jumper for ME to function
         normally.
Note 2 : When MC FRC UPDT jumper is asserted with AC OFF, ME will restore to
         factory default settings.

			ME FW Capsule INSTALLATION NOTES
================================================================================
WARNING:  It is very important to follow these instructions as they are written.
Failure to update using the proper procedure may cause damage to your system.

!!!!! AC failure during update may cause damage to your system and be unrecoverable !!!!!

!!!!! If your current BIOS revision is less than x38, then you must update ME  !!!!!
         Update ME with x38 BIOS using a SuperCapsule
!!!!! Failing to follow the above procedure will switch ME into recovery mode  !!!!!    

Please follow the below procedure to update ME using UEFI iFlash32 11.0 Build 6
   1.  Boot the system to EFI Shell
   2.  Download ME release package
   3.  Unzip the ME release package to HD or USB Flash Drive
   3.  Map the respective storage device in system with the command
           Shell> map -r
   4.  Change the Shell to mapped device file system
           Example: Shell> fs0: (or fs1:)
   5.  Run the IFlash32 utility on the prompt.
       Use MEComplete_xx_xx_xx_xxx.cap file when the whole ME Image update is
       required.
           fs0:\> IFlash32 [File Name] /u /ni
   6.  Reboot system after the update is completed.

			KNOWN ISSUES in 02.01.05.069
================================================================================
- On simulated memory throttling PECI register it was observed that Memory
  Throttling Statistics sensor reading value is update too late. Based on 250 ms
  sensor scanning interval sensor value should be updated after 6 seconds,
  actually it was updated later, up to 15 seconds.
- Too few steps in the ramp generated by SMART & CLST.
- No monitoring capability is reported in NM Capabilities sensor if temperature
  reading source is set to OEM command.
- PEC error is not reported for Send Raw PMBus commands of write/read word and
  block write/read type.
- NM Capabilities event is not sent after disabling then re-enabling scanning on
  its sensor.
- ME Power State Change notification is not sent after Set ME Power State
  command (M3 -> MOff).
- Unstable limiting and Correction Time Exceeded event was sometimes observed
  for memory domain (id 2).
- In a system with more than 2 PSU the PSU discovery procedure is done every 3
  seconds while it should be done every 10 seconds. Too much traffic is observed
  on PMBus.
- Sporadically, after about 50 iterations of warm reset flows with ME configured
  for Always On power mode BIOS hangs just after it sends End of POST
  notification to ME. ME remains operational.
- PSU Proxy setting does not affect Send Raw PMBus commands. It was supposed to
  disable these commands.
- Sporadically, once for about 6000 warm resets BIOS hangs in an assertion.
- Throttling statistics in domain 0 and 1 are equal to 0, when power policy is
  active in domain 0.
- There is no ME Health Event when writing to flash is enabled after previous
  flash wear-out.
- Few percent power limit oscillations were observed when limiting in memory
  domain.
- Power limit oscillations were observed after adding 7 NM power limiting
  polices.
- P-state limit lock was observed two times in longevity tests of power
  limiting enable (policy create) and disable (policy destroy) cycles.
- If power threshold is defined in several NM polices and the power consumption
  exceeds the threshold the NM Alert Threshold Exceeded message is sent only
  for the first policy, not for all polices.

===============================================================================
			02.01.05.069
===============================================================================
- Fixed: ME FW Health Event with Event Data 2 = 0 (Recovery GPIO forced) will
         be generated after IPMI command "Force ME Recovery" issuing.
- Fixed: ME FW unexpectedly resets when SMLink clock held low for a long period
         of time
- Fixed: Sometimes system stops responding after Power Cycle.

===============================================================================
			02.01.05.064
===============================================================================
- First production release of ME
