Hi Nicolas,
Thank you for reply! The "only" trouble is that I need to descrive it as a
pci device. Taking the parallel port as an example is  very usefull for
simple  hardware  as you  made.  But I need some info for write my device
into qemu, in particular the init function for pci device as the ne2000 (In
init function of network card it set pci_conf, should I need to set up? And
what arguments should I put in pci_register_io_region function?).
My emulated device for the moment need to run in i386 architeture so I have
not to be completeness about cpu target etc...
Anyway I appreciate if you can send me your written device so I can see if
it can help me!

Thanks

Ale
