+.It empb: linear space mapping might not work
+PCI card driver is trying map memory space with BUS_SPACE_MAP_LINEAR flag.
+Due to windowed design of Medaitor, it is expected to fail miserably if
+normal memory space access methods (e.g. pointer dereference) are used
+instead of

+methods.
+.It empb%d: couldn't find memory space, check your WINDOW jumper
+PCI memory space access is disabled on a hardware level. The
+.Nm
+driver will work anyway, but only PCI I/O space will be accessible. To enable
+memory space set WINDOW jumper to 4MB or 8MB.
