ssb-sprom data discrepancy

Tue, 17 Jun 2008 23:03:08 -0700

I was interested in modifying some parameters for a miniPCI card and a PCI card in an attempt to increase transmit power and gain, turn on the second antenna on the minipci card and anthing else that would improve performance but before flashing I thought I'd verify the changes and make sure I had my setting right but instead I'm shocked.
So, either the app is displaying the wrong data or the wrong data is being modified so rather than being destructive and bricking a card I thought I'd ask the masters. 


Something that interest me is that the N-PHY cards have 3 antennas  
and according to Buffalo Technology Technical support the  
characteristics for all 3 antennas are configurable in the sprom  
which is supposed to include an option for the middle antenna to be  
in regular or diversity mode.



Is there a table somewhere that decodes the sprom and denotes what  
each bit represents in a combined byte?




The source used in the ssb-sprom app was taken at 1:15am EST June  
17th so it was the latest available from git 24 hours ago.





Here's my session and it's clear that something is wrong: (two  
examples given, due to size I didn't provide all the tests, had  
issues adjusting gain)
