136 #### Disk controllers and disks.
137
138 ## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
139 ## This driver has several flags which may be enabled using
140 ## the "flags" directive. Valid flags are:
141 ##
142 ## 0x0ff Set (1<<target) to disable parity checking
143 ## 0x100 Set this bit to disable DMA interrupts (poll)
144 ## 0x200 Set this bit to disable DMA entirely (use PIO)
145 ##
146 ## For example: "flags 0x10f" would disable DMA interrupts,
147 ## and disable parity for targets 0-3
148
149 sc0 at mbmem0 addr 0x80000 ipl 2 flags 0xff
150 sc0 at vme0 addr 0x200000 irq 2 vect 0x40 flags 0xff
151 sc1 at mbmem0 addr 0x84000 ipl 2 flags 0xff
152
153 ## NCR5380-based "Sun SCSI 3" VME SCSI controller.
154 ## This driver has several flags which may be enabled by OR'ing
155 ## the values and using the "flags" directive.
156 ## Valid flags are:
157 ##
158 ## 0x01 Use DMA (may be polled)
159 ## 0x02 Use DMA completion interrupts
160 ## 0x04 Allow disconnect/reselect
161 ##
162 ## E.g. the following would enable DMA, interrupts, and reselect:
163 ## si0 at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
164 ##
165 ## By default, DMA is enabled in the driver.

169 ## These entries find devices on all SCSI busses and assign
