+ *	This is based on the original LANCE files, as the PCnet-ISA used on
+ *	the Ariadne is a LANCE-descendant optimized for the PC-ISA bus.
+ *	This causes some modifications, all data that is to go into registers
+ *	or to structures (buffer-descriptors, init-block) has to be
+ *	byte-swapped. In addition ALL write accesses to the board have to be
+ *	WORD or LONG, BYTE-access is prohibited!!
