1441.1Sfredette## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
1451.1Sfredette## This driver has several flags which may be enabled using
1461.1Sfredette## the "flags" directive.  Valid flags are:
1471.1Sfredette##
1481.1Sfredette## 0x0ff		Set (1<<target) to disable parity checking
1491.1Sfredette## 0x100		Set this bit to disable DMA interrupts (poll)
1501.1Sfredette## 0x200		Set this bit to disable DMA entirely (use PIO)
1511.1Sfredette##
1521.1Sfredette## For example: "flags 0x10f" would disable DMA interrupts,
1531.1Sfredette## and disable parity for targets 0-3

1581.1Sfredette
1591.1Sfredette## NCR5380-based "Sun SCSI 3" VME SCSI controller.
1601.1Sfredette## This driver has several flags which may be enabled by OR'ing
1611.1Sfredette## the values and using the "flags" directive.
1621.1Sfredette## Valid flags are:
1631.1Sfredette##
1641.1Sfredette##	0x01		Use DMA (may be polled)
1651.1Sfredette##	0x02		Use DMA completion interrupts
1661.1Sfredette##	0x04		Allow disconnect/reselect
1671.1Sfredette##
1681.1Sfredette## E.g. the following would enable DMA, interrupts, and reselect:
1691.1Sfredette## si0	at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
1701.1Sfredette##
1711.1Sfredette## By default, DMA is enabled in the driver.
