141 ## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
142 ## This driver has several flags which may be enabled using
143 ## the "flags" directive. Valid flags are:
144 ##
145 ## 0x0ff Set (1<<target) to disable parity checking
146 ## 0x100 Set this bit to disable DMA interrupts (poll)
147 ## 0x200 Set this bit to disable DMA entirely (use PIO)
148 ##
149 ## For example: "flags 0x10f" would disable DMA interrupts,
150 ## and disable parity for targets 0-3
151
152 sc0 at mbmem0 addr 0x80000 ipl 2 flags 0xff
153 sc0 at vme0 addr 0x200000 irq 2 vect 0x40 flags 0xff
154 sc1 at mbmem0 addr 0x84000 ipl 2 flags 0xff
155
156 ## NCR5380-based "Sun SCSI 3" VME SCSI controller.
157 ## This driver has several flags which may be enabled by OR'ing
158 ## the values and using the "flags" directive.
159 ## Valid flags are:
160 ##
161 ## 0x01 Use DMA (may be polled)
162 ## 0x02 Use DMA completion interrupts
163 ## 0x04 Allow disconnect/reselect
164 ##
165 ## E.g. the following would enable DMA, interrupts, and reselect:
166 ## si0 at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
167 ##
168 ## By default, DMA is enabled in the driver.
