I guess you checked the entire eepron content ;-)
According to the documentation i have, there is no config byte describing the
assignment of antenna sockets. The document says that this byte is a checksum!!!
I will try to get some information.
I found one discrepancy:
The Tiger uses LINE1 for the audio baseband inputs while the ASUS uses LINE2.
Can you cross check this?

Best regards
