+Configuring Ultra-3 DT data transfer support.
+---------------------------------------------
+If you have a board using the SYM53C1010 (only evaluation boards seem to
+be available for now), you may want to give Ultra-3 DT transfer a try.
+For the reasons that FreeBSD-CAM is not yet ready for Ultra-3 and that
+early SYM53C1010 chips need some work-around for DT transfers to work
+reliably, you must apply manually the following additionnal patch to your
+kernel tree:

+
+This change consist in allowing sync factor 9 support to be handled
+by scsi_all.c and a compilation option to be defined in sym_conf.h.
+The driver may only start a PPR negotiation if sync factor is 9.
+This change has been only tested on FreeBSD-3.3 for the moment.
+
+For the PPR negotiation to occur at system startup time, you need to
+configure Ultra3 hard disks in the NVRAM for 80 Mega-transfers per second
+Wide.
+If you prefer to use camcontrol for such a negotiation to be performed after
+system startup, then you have to rebuild either the libcam shareable library
+with the patched version of scsi_all.c, on to rebuild camcontrol using
+the new static version of the libcam library that includes the patched
+version of scsi_all.o.
