Hi, We try to use mylex 150 with 2X18Go (piii550/256RAM) to make hard raid 1. I guest the hardware setup is badly done, because linux does not want to boot: SYSLINUX 1.45 low ("DOS") RAM. Linux needs 608Ko !? thx for help Octave Amicalement, oCtAvE "J'aime trop la vie pour ne vouloir être qu'heureux."
