SerialICE question

[Riko Ho]

Everyone,

I tried to understand :
https://www.serialice.com/Getting_Started

In my case:
I want to see i946 init sequence,

How can I tap it from vendor BIOS ?

I have one debugging system and the other is debugged system,
how SerialICE works between of them ?

When i946 cold boots ....then ??

Cheers
