Dear all,

I see from previous posts to the list that it is possible to use servers
to run freesurfer.  I'm in the process of selecting a machine, and would
appreciate any input anyone might have on which machine is optimal.
In particular I'm concerned about eventual problems described on the
mailing list earlier this month (see thread pasted below), regarding the
ES1000 chipset that apparently comes with Dell PowerEdge servers (I am no
expert with hardware issues such as these so this is all new to me!).
Does this chipset come with all of these types of servers, or is it
possible to order one with an NVIDIA card installed?  Are there better
alternatives wrt to which machine to purchase?

thanks in advance for any input you might have,
best,
Narly.

Hi all,


FYI, this same problem has been bugging me for several months. Most ATI
chipsets have a nice driver installer bundle that, once installed, will
let you run tksurfer without a problem. However, this particular chipset,
the ES1000, which is the chipset on Dell PowerEdge servers, is unsupported
and seems to have been abandoned by ATI/AMD/whoever they are this week.

If you happen to be unlucky enough to have Dell PowerEdge servers with
this chipset and the need to run tksurfer, you're out of luck, until you
put a slightly "better" graphics card in. I just managed to install an
nVidia 8400GS (the x1 PCI-e version - the poweredge PCI-e bus is x8, which
means it won't work with any of the most recent cards, but will work with
slightly older x1 cards) and tksurfer works fine now. I can provide the
gory details if you're in this boat.

   Hi all,

   Im have an onboard ATI ES1000 515E graphics chip.

   Any ideas??
