4GB pamet, vidim vsak jen 3,5 GB

[Bc. Radek Krejca]

Dobry den,

  mam nasledujici problem, poridil jsem server HP ProLiant a nechal si
  do nej dat 4GB pameti. Kontroloval jsem to, BIOS ukazuje 4GB, kdyz
  startuje server, tak take kontroluje 4096 MB, nicmene jakmile
  nastartuje system, tak dmesg, top a spol. ukazuje pouze 3,5 GB cca.

real memory  = 3758043136 (3583 MB)
avail memory = 3678674944 (3508 MB)

  Koukal jsem po netu a FreeBSD 6.1 (o kterem v tuto chvili mluvime)
  by nemelo mit problem s upto 4GB, pokud jsem tedy cetl spravnou
  stranku. :)

  Zatim mam generic default instalaci, vzhledem k tomuto problemu jsem
  se jeste nepoustel dale, dokud se to nevyresi. Je tu sice moznost,
  kterou bych dost nerad, ze proste 1GB vytahnu, jenze to mi server
  zase pojede na doraz a to se mi moc nechce. Bohuzel zkusenost s
  tolika pameti zatim nemam a nic kloudneho jsem nenasel. Diky za
  radu.

  Jeste na zaver pripojuji kompletni dmesg.
