To arxeio lilo.conf poy xrhsimopoiw gia na egkatasthsw to Lilo moiazei

5. Xrhsimopoiwntas to Lilo otan to BIOS den mporei na dei to Root

H lush egkeitai sthn apo8hkeysh toy pyrhna, toy arxeioy apeikonishs

6. Prosbash se terastias xwrhtikothtas diskoys otan den mporei to

To susthma sto xwro ergasias moy exei IDE disko xwrhtikothtas 1GB. To
BIOS mporei na 'dei' mono ta prwta 504 MB toy IDE. (opoy MB shmainei
