[Etherboot-developers] Boot LynxOS with etherboot

[Armin S. <ac...@sy...>]

Hi all,

with the following patch it is possible to boot
a LynxOS KDI image with etherboot. The patch is
against 5.0.4, maybe you like to implement this feature.
In case of response, please CC me, I'm not on the list.

Regards,
