BUGS

     The mcd hardware is  difficult to probe accurately.  Historically, the mcd probe would accept any return values as indicating that an mcd
     drive was present.  Other devices, particularly ne(4) or we(4), would then be incorrectly claimed by the mcd driver.  The driver now only
     accepts result codes known to indicate Mitsumi-compatible CD controllers, but may reject some mcd hardware which  returns other result codes.

     options MCD_PROMISC enables the  original promiscuous probe behaviour. Use with extreme caution.
