I got 2.4.34 compiled now using gcc-2.95.3 and glibc-2.2.5.

kernel.1000 also boots. Great!

What does this mean to me? Is there a "practial" difference in the gcc
version used for building the kernel? Does it limit me in any way using
the compiled kernel?

That sounds to me like a kernel with an initrd.

I got now a kernel that should be ltsp-compatible together with a
ltsp-initrd.

However, mkelf-linux does not accept the kernel.1000 for creating the
tagged kernel image and complains about the format:

> mkelf-linux kernel.1000 initrd-ppc-monolithic-ltsp-1.gz >vmlinuz-2.4.34-l=
tsp-1.1000

kernel.1000: not a Linux kernel image

(I did try this on i686 though - is this a problem?)

What do I do now, to build the boot-image with initrd?

The fw-loader seems to be picky. That's probably the reason for the
special "kernel.1000" format and also the cause, why so few people
managed to get a Netstation 1000 up under linux so far (before I came
accross this project I found none. - On ltsp.org it is documented as not
working).

What is this? Never heard of and didn't use it.

Did a Google search and found some posts by you that make me believe,
that's the tool I need for building the image with the initrd.

Can you point me to a ncdcs download-location?

Thanks

Stefan.
