144 #### Disk controllers and disks.
145
146 ## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
147 ## This driver has several flags which may be enabled using
148 ## the "flags" directive. Valid flags are:
149 ##
150 ## 0x0ff Set (1<<target) to disable parity checking
151 ## 0x100 Set this bit to disable DMA interrupts (poll)
152 ## 0x200 Set this bit to disable DMA entirely (use PIO)
153 ##
154 ## For example: "flags 0x10f" would disable DMA interrupts,
155 ## and disable parity for targets 0-3
156
157 sc0 at mbmem0 addr 0x80000 ipl 2 flags 0xff
158 sc0 at vme0 addr 0x200000 irq 2 vect 0x40 flags 0xff
159 sc1 at mbmem0 addr 0x84000 ipl 2 flags 0xff
160
161 ## NCR5380-based "Sun SCSI 3" VME SCSI controller.
162 ## This driver has several flags which may be enabled by OR'ing
163 ## the values and using the "flags" directive.
164 ## Valid flags are:
165 ##
166 ## 0x01 Use DMA (may be polled)
167 ## 0x02 Use DMA completion interrupts
168 ## 0x04 Allow disconnect/reselect
169 ##
170 ## E.g. the following would enable DMA, interrupts, and reselect:
171 ## si0 at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
172 ##
173 ## By default, DMA is enabled in the driver.
