I dont know if this helps,
but are you sure you let the image finish building, if you are unsure you could allways try the button called rebuild image.

In /usr/share/pluto/diskless you can delete the XX folder which represents the id of you computer, inside the image resides, i deleted the complete folder called 48
then went oni the pluto admin home page and on the Orbiter page i selected Rebuild image.

Hope this helps,

You would need to get the correct module for the driver, precompiled for that kernel,
then it might even autoload, if not you might need to edit a startup script (init script)

The Kernel painc relates to driver problems with ethernet cards. On some motherboards a bios upgrade will fix it, like the Asus M2NPV-VN. On others you may need to add a NIC with onboard PXE boot. Its more of a Linux issue than anything else. And a pain since MB vendors don't put Linux support high on their lists and the software doesn't come from them or get much support from them.

i do have the driver file for one of the motherboard its a Lan_Marvel inside a intel board
as for the other one is a Nvidia lan so the driver is available also.
what i don't have right now is a way to build them to linuxmce, no kernel source and no way to do it so i will pause that for now.
one thing i can allways do is to get two 1GB lan cards that works, but none that i have do.
someone who have instaled from source can compile those and put them online for us
as modules.

thanks

PS: i will post some post in my natural language (portuguese) in my own site

Those are the two NIC's that have been troublesome before. The Marvel is more troublesome in my experience. The nVidia should behave but BIOS issues can't be discounted.

I picked up some IBM NIC's with PXE boot rom on them that work fine off eBay. IBM is pushing Linux hard so they have good drivers in distribution.

Havent had trouble with realtek cards either.
