cd-images with custom kernels
Teemu Ikonen
I'd like to test debian-installer on a brand new PC with an ASUS A7V600
motherboard. This motherboard contains a 3Com 3C940 ethernet controller,
which is not supported even in the mainstream stable kernels and thus my
attempt at installing sarge with the Beta 1 debian-installer images
(netinstall) stalled on the network device detection.
I've now successfully built a kernel-image .deb with a patched 2.4.22 kernel
source, which should support the 3C940. Is there a howto or some other
documentation on building d-i cdrom images with a custom kernel and modules?
I tried to decipher the documentation on d-i CVS, but must have missed the
necessary information, if it was there in the first place.
Thanks and best wishes,
Teemu

I suppose you could just continue past that and do a CD install. Of
course you'd then have to get a fixed kernel onto the installed machine
somehow before it could be put on the net.

We're not at the point of having a HOWTO for this yet. What you need to
look at is the linux-kernel-di package (kernel/linux-kernel-di in CVS),
whose README describes how to make it generate udebs from a kernel-image
.deb. Then you'll want to look at the debian-installer source package
(AKA the build/ directory in CVS), whose README describes how to put
udebs in localudebs, and how to build it. You'll probably have to edit
something in its config/ directory to make it use your new kernel
version.
People have gotten custom kernels to work I know, but I'm still waiting
for a real HOWTO from someone who knows how to do it.

Thanks for the reply,
I actually got this far, I built the kernel udebs and put them into
localdebs, the D-I build ("make image") also finished successfully and
produced an iso image to build/dest.
But, this image is only about 5 MB in size and doesn't contain the driver
image files (e.g. net_drivers-image.img), only the cdrom-image, initrd and
the kernel. Any idea on how to make the additional drivers?
Next I took a look on the debian-cd scripts, but found that they'd need a
writable mirror of the Debian archive. This was a bit discouraging :) Maybe
I could copy the contents of the Beta 1 cdrom and replace the driver images
with the ones I've made myself, assuming I can actually make them?
Best wishes,
