Hi - we use several different hardware flavours of 64-bit linux desktop / cluster nodes and have had pretty much NO problems installing linux and getting FSL to work. If you'd like a list of the exact linux flavours we used we can send this info. Cheers. On 10 Sep 2007, at 09:10, Wen, Wei wrote: > Thanks Steve. > > You are right on getting a 64-bit machine.
