Thanks for your reply, I've managed to create my new rtl8139.zrom.
And it works like a charm!

Nearly like a charm. Well, the PXE part does work now, but the BTX
part is not good.

It doesn't matter if I use an pxeboot from an 6.3 system or an 7.0
system. This happens with both emulators/qemu as with emulators/qemu-devel.

Any idea where to look now?
