ATI Mobiliy FireGL T42p and T43p chip differences

[poshgeordie]

At work we urgently need a new ATI Mobility FireGL PCI Express 216ydjaga23hg for a customer's T43p

We do have some T42p boards with good ATI Mobility FireGL T2 216ybfcga16fh chips.

I can't find any information on either chip (though it is possible to buy T2 chips via Taiwan).

Does anyone know if there is any actual difference between these chips?

Unfortunately I don't have either board FRU.

Thanks in advance.

Don't think it's going to work because FireGL V3200 found in T43p is PCI-E, but FireGL T2 is AGP.

Not directly related to T43p, but...Even though pinout is the same on all T40-T42 GPU's (even p-models), I have examined this earlier and p-models have for example more pullup resistors near GPU.

Thanks Raceboy - I thought they were completely different and I've also learned something new too!
