 #      Sample kernel config for PS/2 with MCA bus

-#      BEWARE: do NOT use MCA-enabled kernel on non-MCA machine
+#      WARNING: DO NOT USE UNLESS YOU ARE PREPARED TO DEAL WITH PROBLEMS.
+#
+#      BEWARE:
+#       MCA support in NetBSD is still very experimental at this
+#       stage and should be used with extreme caution. MCA-enabled
+#       kernels won't currently work on non-MCA machines and it's
+#       not wise to try even try it unless you are prepared to deal
+#       wish strange hardware failures. Please note that MCA
+#       support doesn't yet reach standard NetBSD quality,
+#       should be really used only for experimentation and is provided
+#       specially and only to make access to the code easier for people
+#       who wish to help with PS/2 development.
+#       See also sys/dev/mca/TODO for list of problems and current list of
+#       projects. If you try this out and encounter any problems, please
+#       let us know via send-pr(1) or ask on port-i386%NetBSD.org@localhost.
