The serial ports (and other stuff) are handled by a Winbond W83977TF chip, which I suppose is connected to the PIIX4E's ISA bus...
the 83977ef is supported already.
What's the diff between a TF and EF?
Looking at the data sheets...
- The TF suppports 13 IRQs, the EF only 12.
- The TF has "23 programmable general purpose I/O ports; 3 dedicate, 20 optional", while the EF has only "14 programmable general purpose I/O ports; 6 dedicate, 8 optional".
Oh, and the TF is compliant wih the Microsoft PC97 Hardware Design Guide; the EF with the PC98 version of same. Big Deal.
Other than that, they look identical.
