Titolo: Scomparsa di RAM

Salve a tutti,
Server HP PROLIANT 380 G4 (x86_64)  Fedora Core 3 x86_64
feci poco tempo fa un upgrade al server che da 2 GB di memoria fu portato a 
4 GB.
ma fedora ne vedeva solo 3.6 (supporto nel kernel per piu di 2 gb attivo) 
provai aggiornando il tutto all'ultimo kernel
disponibile ma niente da fare.
4 mesi dopo per problemi vari formatto tutto.
Installo CentoOs 4.2 x86_64 vado a controllare la memoria ed ecco di nuovo 
qui la sopresa:
Linux web.xxxxx.xxxx 2.6.9-22.ELsmp #1 SMP Sat Oct 8 21:32:36 BST 2005 
x86_64 x86_64 x86_64 GNU/Linux
 total       used       free     shared    buffers     cached
Mem:       3607080     262640    3344440          0      22572     178776
-/+ buffers/cache:      61292    3545788
Swap:      4063216          0    4063216
Non è possibileeeee mi vede ancora solo 3607080 di memoria!!
il resto che fine ha fatto ?!!
ho fatto da bios tutti i test possibili sulla memora ma non risultano 
esserci errori.

mmmmh.....non e' che per caso che c'e' qualche risorsa hw che te la 
puppa? ad esempio le mobo con scheda video integrata.....anche se 400 MB 
svaniti mi sembrano parecchi, anzi senza il mi sembrano

 svaniti mi sembrano parecchi, anzi senza il mi sembrano
400MB di memoria per la scheda video interna? Mamma mia Nemmeno le 
console di nuova generazione.............
Il problema -spero- non sia li.....

infatti non è li perche il dl dovrebbe avere una scheda da 16 mb.
inoltre prima dell'upgrade erano visibili tutti e 2 gb.
.....

io non scarterei l'ipotesi .. ho guardato adesso nel mio portatile con 
sk video ati 9700, e mappati (non presenti sulla scheda!) come frame 
buffer ho 256+64=320Mb di memoria.
ciao
