PRODUCT_LINE: BCM
============================================

Software Update Name: BCM360.331-BIOS

Applicable H/W Platforms: BCM200, BCM400, SRG200 1.0, SRG400 1.0

Applicable S/W Platforms:  BCM 3.6, SRG 1.0 based on BCM 3.6 

Category: GEN 

Installation Recommendations: This patch should be applied to all new 
installs of BCM 3.6 and SRG 1.0 based on 3.6. Existing installations 
should have this update applied if they are experiencing any of the issues 
that are corrected. There is no need to schedule specific maintenance 
to apply this upgrade if there are no reported issues. In those cases, 
systems should be updated at the next regular service opportunity.

Component & Version: BIOS 02.03.50 R2
                     SSMTest Utility 37.00.10.01

Dependencies: Required patches - None
  
Product Dependencies - None

Size: 14 MB

System Impact: time to apply approximately  25 minutes

Does patch application force reboot: Yes, 2 reboots

Other impacts: All services are unavailable during the patch process.

Limitations: During the first step of the patch (BIOS Upgrade Validation), we check 
   that the hard drive has factory-compliant partition sizes.  If the partition sizes 
   do not match those of a factory hard drive, the patch will fail to apply.
   If this occurs you must re-image the hard drive with the "BCM Imaging tool" or
   install a Factory hard drive FRU.

Patch Removable: No

Description:
-----------

Note: If you have BCM360.303-BIOS installed on your BCM, or if this BIOS was installed
   in the factory, this patch is not required and will fail to apply.  

IMPORTANT: Because this patch reflashes the BIOS, it is essential that the process 
  be allowed to run to completion. The BIOS update process takes approximately 30 
  seconds. If interrupted, the BCM could be left in an unbootable state. In the 
  unlikely event that the BCM is left in an unbootable state, please contact NETS.
  The probable remedy will be to replace the Base Function Tray.

The following issues are addressed:

1. Very rare system lockup
   Very high levels of IP traffic have very rarely been seen to cause system 
   lockups. This problem was traced to a register setting in the BIOS that sets 
   the buffer memory drive strength.
   CR ID Q01282131

2. Three consecutive incomplete BIOS boots causes wrong CMOS settings
   Some wrong settings could cause BCM to run with reduced efficiency.
   No CR 

3. Hard disk drive S.M.A.R.T. monitoring can cause system lockup
   S.M.A.R.T. require a keyboard response when it detects minor degradations in 
   the hard drive. These are not fatal errors in themselves, but the BCM is 
   headless and will lockup, as there is no keyboard to respond with.
   No CR

4. BIOS version information stored in system inventory and registry of BCM 200/400 
   does not necessarily reflect the real BIOS version. The system inventory file is 
   stored under "F:\Program Files\Nortel Networks\VoicePlatform\wwwroot\inventory.xml".
   The BIOS version is stored in the registry under
   "Software\Nortel Networks\Platform Services\BIOS Version". 

   The Actual BIOS version can be verified by rebooting to CMOS and looking in 
        "Advanced version information" under "Advanced" Tab.
   CR ID Q01340408

5. Patch wrapper is modified to correctly report issues and errors found before and 
   while patch is being applied to the system.
