I think the author means his 10/100 Realtek card works, not a gigabit
one:

realtek 8139 is the fast ethernet model.

anyway...

I too am having very bad luck getting gigabit adapters to work with an
Ultra 5.
According to the Ultra 5 specs at Sun:
http://sunsolve.sun.com/handbook_pub...ystems/U5/spec
the PCI interfaces are all 5 volt. What I have been wondering is if
the chipsets
used in these gigabit boards - Marvell 88E8001in the DGE-530T, Realtek
8169S
in the ENLGA-1320 - are limited to 3.3V PCI slots.

The RealTek documentation is kinda cryptic, they claim "3.3V
signaling, 5V
PCI I/O tolerant". I guess that means it works only in 3.3V, but won't
blow up
if you mess things and put it in a 5V slot.

Alas, both D-Link and Marvell offer very poor documentation on their
products (or I am too lazy to search), so I don't know if they are
supposed
to work on 5V or not.

Good luck there, I'll probably just give up running gigabit on the
Ultra 5...
