SB16PCI

I have developted a little driver on QNX4 to use SB16PCI.
At first this card used an ES1371.
Now I buyed other SB16PCI (same name and same model) that use a CT5880.
Has someone information about this chip-change? And someone has the
documentation of CT5880 to know the diffence betwen ES1371?

Thank’s in advance.
