    126 ## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
    127 ## This driver has several flags which may be enabled using
    128 ## the "flags" directive.  Valid flags are:
    129 ##
    130 ## 0x0ff		Set (1<<target) to disable parity checking
    131 ## 0x100		Set this bit to disable DMA interrupts (poll)
    132 ## 0x200		Set this bit to disable DMA entirely (use PIO)
    133 ##
    134 ## For example: "flags 0x10f" would disable DMA interrupts,
    135 ## and disable parity for targets 0-3
    136 
    137 #sc0	at mbmem0 addr 0x80000 ipl 2 flags 0xff

    139 #sc1	at mbmem0 addr 0x84000 ipl 2 flags 0xff
    140 
    141 ## NCR5380-based "Sun SCSI 3" VME SCSI controller.
    142 ## This driver has several flags which may be enabled by OR'ing
    143 ## the values and using the "flags" directive.
    144 ## Valid flags are:
    145 ##
    146 ##	0x01		Use DMA (may be polled)
    147 ##	0x02		Use DMA completion interrupts
    148 ##	0x04		Allow disconnect/reselect
    149 ##
    150 ## E.g. the following would enable DMA, interrupts, and reselect:
    151 ## si0	at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
    152 ##
    153 ## By default, DMA is enabled in the driver.
