Hi Bart,

Changing focus...

The first error reported in boot.log is:

   ERROR: Port 0xac1c is not available (outw), 
          "save_vga_state" failed.

Since the port number doesn't appear in hwinfo or lspci, it seems that
adding some debug statements to dosemu might help.

The message above comes from ports, notably port_not_avail_outw() which
calls check_crit_section() which spits out the message.  Looks like I
need to trace backwards to see how/why port_not_avail_outw is being
passed address 0xAC1C.  Have you any suggestions of a better approach?

Regards,

David
