Re: [Libreboot-dev] [Libreboot] new T400 beta ROMs for testing

[Persmule]

Hi Marcel and Leah,

My image was patched properly with a gbe section for my t400s' original
mac address. The possible fault is that the gbe section I used to patch
the image was generated by an older version of ich9gen, but the
difference between it and the product of the newest ich9gen is only one
byte (the 17th byte is 0x24 in the older but 0x44 in the newer).

Could the one-byte difference be the cause?

I cannot access my t400s now, but I can give the report for the newest
image patched with the new gbe section once I get home tonight.

that I could see my wifi-networks but not connect to them.
Ethernet-connection didn't work neither. But anyway: now with the
correct mac both (ethernet and wifi) work. > Another thing that changed
