Dear list users.

My server detects less memory than it available. 

	Available memory according to the BIOS 4049MB.

	System sees only 3.7GB ???
	Mem:  3799580K av, 1606816K used, 2192764K free, 468K shrd, 376972K buff
	Swap: 8192992K av, 0K used, 8192992K free 1037532K cached

OS RedHat 2.7 standard kernel.
	Linux atlas.es.usyd.edu.au 2.4.7-10smp #1 SMP Mon Dec 10 13:08:57 EST 2001 i686 unknown

Hardware PowerEdge 4400. 
	( supports 4GB )

Additional problem:  
	random crushes, trying to to find out why.

Questions : 	1) Any comments on why top only shows 3.7 Gb are welcome.

Thank you.
