Firmware HUB (ICH7) programming support/modes.

Firmware HUB (ICH7) programming support/modes.


I have looked throught the ICH7R spec and can find no defination of what programming (write) Modes are supported on the ICH7.

The LPC section iof ICH7 indicates that the bus does not support memory writes. But yet I can write the FWH using memory write.

I am currently writing the Firmware hub single byte memory writes at a time. This is to slow for my needs.

The LPC spec says that the Firmware should support multibyte writes (1,2,4,16,128 Bytes)

What I need to know is how are these mode supported on the ICH7R ?

Is there any documentation supporting this functionality ?
