What does a socket 479 Pentium M pinout look like?

[ikeo]

I'm trying to figure out if the Banias Pentium M's can be upgraded to a Dothan Pentium M.
I imagine Dothan Pentium M's are socket 479's and Banias is socket 478?
Does anyone have any pictures of the two (the pins)?
Will a Socket 478 Pentium M work in a Pentium 4-M socket?

Thanks guys.

Dothan and Banias use the same socket. Some of the chips have 479 pins, some have 478, but they all use the same socket. It will depend some on the chipset. The 855 chipset should support 400mhz FSB Dothans. The 915 based chipset will support 400mhz FSB banias and dothan, and also 533mhz FSB Dothan.

A 478 pentium-m will not work in a pentium 4-m socket. They have the same number of pins, but they are not electricly compatible.

Thanks for the quick response. This explains a lot.
All I need now are pictures ...
I buy and sell processors ... and I have been presented with the opportunity to buy some Pentium M's. I want to know what I'm getting and I want to know what laptop to buy to test them.

Thanks again

You are the man!
Thanks for getting that for me ... I was getting ready to wade through the Intel website later today to find it ... whew!
