What makes you say the card should have vector 300?

Yes, both PTB and TXA uses a floating vector. PTB also have a higher 
"priority" in the configuration scheme, so it comes first. Which means 
the vector of TXA becomes 310.

Note that this is the vectors the OS is assuming the device will be 
using. It does not mean that the actual hardware is using those vectors. 
That is what the switches are for. But they should match what the OS 
expect... Or else things will not work well.
