You guess right. Most recent cards have a firmware eeprom and the tda10046
will boot automatically from it.
The handling of the eeprom seems to be a bit odd on the T200, but if you
don't have problems...
Adding a firmware file should not give you any improvement. I recently
found that the tda10046 doesn't honour the boot flag if there is a eeprom.
By the way: about a month ago, i updated the driver. Do you use the
recent version?
