merci pour a tous ceux qui m'ont repondu. (juste pour info, mon bios m'indique bien 2Go au d�marrage.)
je recompile.... merci Luc A 16:59 07/05/2003 +0000, Fran�ois Boisson a �crit : >Option de compilation du noyau 2.2.x: > >Ca devrait r�pondre � ta question (2�me paragraphe et suivant) > >Fran�ois Boisson > >CONFIG_NOHIGHMEM: > >Linux can use up to 64 Gigabytes of physical memory on x86 systems. >However, the address space of 32-bit x86 processors is only 4 >Gigabytes large.
