Q. What is the PC motherboard AT Bus incompatibility?
A. PC 386 Motherboards that use the SYMPHONY CHIP SET with a chip identified as 461 and marked v073 do not operate properly when doing 16-bit transfers on odd byte boundaries.
This deficiency results in incorrect operation of LAN²LAN when installed in a PC using the chipset and causes the WD diagnostic to fail during the High Speed Ports test.
If you experience a problem when you run LAN²LAN in a 386 clone, run WD. If you get an error code in the 4141-4147 range, inspect your PC to see if it contains the bad chip set.
