It's worth noting that there's a scale to all this.  The driver
comments imply that the card will push 100Mb if you have enough power
in the CPU ... defined as 400Mhz.  Given the price of this card
... and the fact that less-than-400Mhz CPU's are rather rare, and that
this is only an issue for high bandwidth applications ... the rl cards
might fit for you.

We use them extensively in workstations... even diskless.  The reason
being that with modern processors, they perform adequately ... and
although they take up extra CPU ... CPUs are rather under-utilized
resources in most workstations.

Dave.
