# Sun3 "si" SCSI controller (NCR 5380)
# This driver has several flags which may be enabled by OR'ing
# the values and using the "flags" directive.  (PR#1929)
# Valid flags are:
#
#	0x01		Use DMA (may be polled)
#	0x02		Use DMA completion interrupts
#	0x04		Allow disconnect/reselect
#
# E.g. "flags 0x07" would enable DMA, interrupts, and reselect.
# Note: these values are quite a bit paranoid...
