RE: [Xen-ia64-devel] eepro100 HVM NIC

["Zhang, Xing Z" <xing.z.zhang@xxxxxxxxx>]

I get the wrong re-mapping from windbg(I didn't
see it from driver's debug output before). Your patch resolves
this issue. With it, windows map card's MMIO begin at 
0xC4000000 and I don't see the graphic issue that you 
mentioned.


Good good study,day day up ! ^_^
