34 * BAH (SMC 8bit ARCnet chipset) k/dpi
35 *
36 * The SMC 8bit ARCnet chip family uses a register and a memory window, which
37 * we get passed via bus_space_tags and bus_space_handles.
38 *
39 * As the reset functionality differs between the Amiga boards (using the
40 * 90c26 chip) and middle-aged ISA boards (using the 90c56 chip), we have
41 * a sc_reset callback function in the softc, which does a stop function
42 * (reset and leave dead) or a reset function depending on wether the 2nd
43 * parameter is 0 or 1.
