  20.      _bbbb_uuuu_ssss  The type of I/O bus the map is for. Valid I/O bus types are
  21.           ADAP_VME,ADAP_GFX,ADAP_SCSI,ADAP_LOCAL,ADAP_GIO,ADAP_EISA,ADAP_IBUS,
  22.           ADAP_EPC,ADAP_DANG,ADAP_PCI.

  27.           This defines the space on the I/O bus to be mapped. Valid spaces for
  28.           each bus are as follows.

  48.      driver. PIO maps can be _F_I_X_E_D or _U_N_F_I_X_E_D. _F_I_X_E_D maps provide the driver
  49.      with a kernel address which can be used as a normal pointer to access the
  50.      bus space. _U_N_F_I_X_E_D maps require the use of special routines access to the
  51.      bus space.
