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