63 hardware is difficult to probe accurately.
66 probe would accept any return values as indicating that an
68 drive was present. Other devices, particularly
72 would then be incorrectly claimed by the
74 driver. The driver now only accepts result codes known to indicate
75 Mitsumi-compatible CD controllers, but may reject some
77 hardware which returns other result codes.
79 .Cd "options MCD_PROMISC"
80 enables the original promiscuous probe behaviour. Use with extreme caution.
