Hello Andreas,
I hate to say it but, I don't think coreboot would be the right solution
for you. The SIS 5598 is not supported by coreboot and would take some time
to develope it. With it being an oolldd chipset it may not be worth it.

On the other hand I have had some recient experiances with Intel LAN's and
could probibly offer some help. Etherboot or the Intel Boot Agent are
probibly the solutions that would work for you. Most propritary bios's are
made up of modules. There are utilities out there that will extract the
modules from the bios image. You simpley replace the exsisting network
module with one of the two mentioned above, use the utility to put it back
into a bios image and flash the bios.

The first thing you need to figure out is what kind of bios it is: AMI,
Award, or Phoenix.
Hope that helps.
