+== Logging ==
+
+The 32-bit drivers do some interal logging.  The extract this data
+
+{{{
+copy alsa32$ alsa32.log
+copy alsahlp$ alsahlp.log
+}}}
+
+It appears that the logs are clears by the copy.
+
+
+== Trap Dumps ==
+
+If you are getting kernel or driver exceptions, a trap dump volume can often get you the data to figure out where and why it is happening.  See
+[http://home.earthlink.net/~steve53/os2diags/TrapDumpRef.txt]
+for a setup guide.
+
+== The Kernel Debugger ==
+
+There are times when you just has to watch the code execute to understand the issue.  The kernel debugger can help here.  You and second system and either a serial port to or a supported NIC to use the debugger.  You can not use a NIC for debugging driver initialization and such.  Not enough to the OS is loaded.  However, NIC debugging can make working other areas of driver operation go faster.
+
+The kernel debugger comes in two flavors.  There's the traditional command line debugger.  There's the ICAT source level GUI debugger.  Which is best depends on which part of the driver code you are working on.  The source level debugging is handy, but it can be slow over a serial port.

+More to come...
