Other devices, particularly 69.Xr ne 4 70or 71.Xr we 4 , 72would then be incorrectly claimed by the 73.Nm 74driver. The driver now only accepts result codes known to indicate 75Mitsumi-compatible CD controllers, but may reject some 76.Nm 77hardware which returns other result codes. 78.Pp 79.Cd "options MCD_PROMISC" 80enables the original promiscuous probe behaviour. Use with extreme caution. 81
