Its not possible from the command line. You normally install
a NIC via Device Manager or you could copy the .sys file
to c:\windows\system32\drivers
and the .inf file to:
c:\windows\inf
(instead of default name eg oeminfo.inf or somesuch use a
descriptive name eg 3c905.inf)
and when you boot windows should detect the card and install the
driver. (In theory)
