Congratulations, your kernel is in good shape. Now you're dealing with userspace issues. You can try bypassing most of the init process to see if you can get a prompt. Add init=/bin/sh to the kernel command line. > > - do the devices need to be created in the FS before building the ramdisk > and subsequent ACE file ? Yes, you can statically create the device files. MAKEDEV will do this for you.

That depends on your rootfs.

Easiest way: copy from the /dev tree in a running Linux machine. Cheers, g. -- Grant Likely, B.Sc., P.Eng.
