About 82810e north bridge

[Deepak Kotian]

Hi,
    There seems to be  two devices in Intel 82810e north bridge, one is Memory controller
    Hub and other is Graphical controller HUB.
    Is it OK to just do the initialization for Memory controller HUB
    and forget about Graphical controller HUB.

Also, I saw 82815ep on linuxbios tree, which has support for 
    MCH only and no AGP. This is very much similar to 82810e with
    some address changed.

What would happen if I support MCH for 82810e , will LinuxBIOS
    still come up. Could someone please give an opinon on this.

Thanks and Regards
Deepak

I think so.

I don't think this hardware is at all well tested, so if you can fix it, 
we would be grateful.

OK,
One more question, would the messages come up on the console if I
do not the initialize Graphical Controller HUB.
There is an option in the LinuxBIOS for VGA_CONSOLE or SERIAL_CONSOLE
to display messages on the screen.
Would VGA_CONSOLE be OK without the above initialization.
Could one please elaborate on this.
