If you have hardware which requires newer a kernel version for booting FAI, you can use the grml kernels. I've just put versions 2.6.33 and 2.6.35 into the squeeze repository of the FAI project.
If you add the line below to your /etc/fai/apt/sources.list file, you can replace linux-image-486 with linux-image-2.6.35-grml in your /etc/fai/NFSROOT and after calling make-fai-nfsroot you will have the 2.6.35 grml kernel inside your nfsroot. Don't forget to call fai-chboot(1) otherwise, you may boot the old kernel. The amd64 version is called linux-image-2.6.35-grml64. deb http://fai-project.org/download squeeze koeln This works using FAI 3.4.4 with squeeze and lenny. -- regards Thomas
