+Troubleshooting:
+----------------
+
+It has been reported that the MMU.library marked the LAN part
+of the card as invalid in at least one Zorro-III configuration
+such that the respective I/O space got inaccessible to the driver.
+Should "muscan" report "I/O space Invalid" for the slot assigned
+to the card (compare with "showConfig" or "Scout->Expansions"),then
+an additional line in the MMU configuration file might help. Add
+the following to the MMU-Configuration:

+For 2588 123 SetCacheMode {base} 0x10000 Valid CacheInhibit IOSpace
 
 Changelog:
 ----------
 
+2.15  - fixed multicast mapping code
+      - added recent Microchip OUIs to MAC address validation list
+        (2020 and later)
+      - disabled automatic MMU configuration as commonly redundant
+
+2.13  - explicit MMU parameters for LAN address space, if mmu.library
+        is present in the system
+
+2.11  - try to finish up auto neg and duplex setup when going online 
+      - improved startup/shutdown of the server process
+
+2.10  - option to set MAC address for first board explicitly
+
 2.9   - better support for Envoy: automatically select a higher
         task priority in presence of Envoy services
