Many changes were made since the last update. Logical drives now show up as luns to upper layer, so Probe Multiple Luns must be enabled to detect more than one array. Previously, issuing multiple commands simultaneously was not fully implemented... there is now a #define MULTI_IO which can be set to 1 to enable fully parallel io which may improve performance (I haven't done any benchmarks yet). I still set MULTI_IO to 0 by default because even though it worked stably on one system I tested under, another one was having problems (locks after about 20 minutes of heavy io with no error messages). Some other minor performance/stability enhancements were also made. Any testing or benchmarks done with MULTI_IO enabled especially appreciated.
Also, there will very soon be a megamgr utility released for dynamically configuration of the drives. This will use the slang library and look similar to the Ctrl-M utility from startup.
