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