Didn't find any info on configuring the mbus speed. But I did
see you'll need PROM rev 2.8v2 for SM41's and PROM rev 2.10 to
run SM51, SM520, and SM521's. Don't know the what the latest
revision is, but your 2.5 is looking a little old. If you want
new proms, better hurry, support for these things ends completely
around June 2000.
