Ok. For performance you may want to use md to strip all but the root
partition.

Make sure that mainboard can cache 128Mb - I think it can

180's with 512K cache would be better if you can get them. You want

Set SMP=1 in the makefile and build a kernel

Look for good data rates (head read rate) and seek rates.

That'll work fine. You need no different utils for SMP
