Yeah I thought something similar, but I switched out with an adapter that
is from Sun (it's actually a very
short cable....it was one we got with either an E250 or E450 we ordered at
a previous job). No luck so far.
I'm going to check out the prom here in a sec, and see if there is any
settings that might make a difference.
I'll post if I have any luck.
