I am in a similar position, except I recently upgraded my server (Compaq ProLiant 6400R) by adding two more Xeon 500/100 Mhz L2 1 Mb and added 4 Gb dram to the original 1512 Mb .. now I am in the same sort of position with FreeBSD telling me that it will be ignoring the top 1512 Mb or there abouts > There is no other option, since this is a hardware limitation. My Xeons are the 32 bit versions so I suppose that in my case I get to use PAE ?? or do I loose the "top" 1512 Mb, or does my machine loose that memory completely and I would be better moving it to another machine ?? thanks in advance most kind regards jonathan -- ================================================================ powered by ..
