Yupp. This looks like the problem. A reboot of the portmaster and the
MAC shows up as 00:80:ad:05:7c:a5 but after a few minutes/hours/days it
sets itself to 0D:0A:57:41:52:4E. My Hex to ACSII is a little rusty but
that looks like what you got too. A quick check shows Boot ROM version B.

Fortunatly I have a spare PM for the moment and I will swap the boot ROMs
to fix the problem until I can get a new one from Livingston.

Thanks for the suggestion!
