However, unlike our existing PowerEdge 2650 machines, they're only recognising about 3.25 GB. The machines are pretty much standard, with no extra cards (just the built-in MegaRAID). As a last resort, I've tried rebuilding the kernel with MAXMEM=(4*1024*1024), which produces some really fun crashes (which I can supply if necessary). The BIOS seems to be devoid of anything remotely useful to tweak. Any ideas? Here's a dmesg from the non-crashing kernel: [note, the first line is from memory and might be incorrect] 786426K of memory above 4GB ignored Copyright (c) 1992-2004 The FreeBSD Project.
