When compiling a Javastation kernel with netbooting capabilities, one should take care of the following things:
Please take a look at the
KernelStatus page.

compiling
instead of building a bzImage (which is typically for i386 kernels), we are going to build a vmlinux:
<![CDATA[# make dep
# make clean
# make vmlinux
# make modules
# make modules_install]]>
do not forget to convert the image to
a.out format, if you are going to netboot:
<![CDATA[# elftoaout -o /tfpboot/krups-kernel-nfsroot-2.4.20 /export/magnesium/usr/src/linux-2.4.20/vmlinux]]>
host system
Building the first Javastation kernel is a bit of a chicken-and-egg problem; you have to boot a Javastation to build a kernel on the Javatstation, to boot a Javastation etc....
Therefore, it's very easy to have a Sun-4/linux box around as a compile host.
When you've made a filesysem (
NFSRoot), you can chroot in it:
<![CDATA[# chroot /export/magnesium
#]]>
In this chroot-ed environment, you can build the kernel to boot the Javastation. It is of course also possible to download a precompiled kernel. See
