The later WD100n-xx[n] (alphanumeric suffix) controllers for IBM PC and AT buses use the WD1010 or WD2010 controller chips rather than an 8x300/305 processor, so they don't really have the same kind of firmware to be dumped as the earlier controllers. Some of them do use a mask-programmed 8052, numbered WD1017.
