Idea... Before the "grand NMBCLUSTERS reorg", the default number of clusters was 256 (or 512 if GATEWAY). Now, it's 512 + 16 * MAXUSERS (ie: 672 in GENERIC and BOOTMFS). How big is a cluster? I'm not familiar with this area very well, but if it is dynamically allocated does the fixed size of the control structure (mb_map?) take up space? If so, perhaps it might be an idea to put ``options "NMBCLUSTERS=256"'' into the generated BOOTMFS config file? If course, I am not familiar with this area of the kernel, so I may be _way_ off course.. :-) (How much of the VM system is configured before the lower 640K of ram is reclaimed? Could this be a problem?) -Peter
