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