It definatly works in 5.0. I was using this up till about a month ago:
hint.scbus.0.at="ahc0"
hint.scbus.0.bus="0"
hint.scbus.1.at="ahc1"
hint.scbus.1.bus="0"
hint.da.4.at="scbus1"
hint.da.4.target="0"
hint.da.5.at="scbus1"
hint.da.5.target="1"
However, cam_periph.c on -current has a bugfix that doesn't appear
to have been MFC'ed:
revision 1.40
date: 2002/08/24 02:47:01; author: peter; state: Exp; lines: +9 -11
Fix unit wiring. Also, change the variable "hit" to "wired" so that it
is more obvious.
ie: wiring works better in -current than -stable. :-(
Cheers,
-Peter
