(Modified because it is userspace and plugs into other modules - but the device access specific parts are not modified). I wanted to know which chipset exactly does Qemu emulate? Does it make a difference if it is different from the 82547? I see that 82547 is in the e1000 family, so should my driver work for a variant of the e1000 family which Qemu or vmware supports, for eg, vmware supports 82545EM, so can I us= e my driver for 82547(maybe I will need some modifications) and will it work with the emulated e1000 nic in vmware? Which chipset does Qemu's e1000 emulate? Thanks! Anjali
