[Qemu-devel] RE: eepro100.c

[Michal Filka]

Hi

Earlier post was one big mistake. Everything is compiled now (from kvm-88 
sources).

I don't want to corrupt present kvm installation, or better to say, I want to 
modify it as small as possible. Could you suggest me what should I replace or 
how to run new compilation instead of old one without installing?

Thanks
Michal Filka
