Hi,

I'm able to boot Linux 2.6 on ML403 board (with a ramdisk file system).

However, during the kernel booting, it complains that "No network devices
available," So I figured I probably didn't enable the ethernet driver in the
kernel.

>From doing "make menuconfig", under "Device Drivers" --> "Network device
support" --> "Ethernet(10 or 100Mbit)", I checked the box of both "Ethernet
(10 or 100Mbit)" and "PowerPC 4xx on-chip Ethernet support." I then
save/exit the menuconfig to compile the kernel again. I've attached the
error output at the bottom.


The virtex eth device is not the same as 4xx on-chip Ethernet, so
CONFIG_IBM_EMAC will not work.  You need the xilinx_enet driver (which
is not in mainline).  It might be in MontaVista's 2.6 tree.

I think people have posted patches for it to this list, so try
searching the archives.  (I don't have a link off the top of my head.)

    The MV 2.6 Xilinx_edk based TEMAC driver has been posted to this list several times.

    As of the last incarnation I tried it had no MII/PHY support and you had to manully change the speed of the driver 10/100/1000 by editing the code.
