Hi Thorsten and Sven. Just to complete the draw, right now my situation is this one. On my machine with the kernel 2.4.24 compiled with the config that i given to you. I've got on disk0 a primary partition sda2 formatted ext3 with the entire os later i,ve created other primary partitions sda4 and sdb4 and after a raid1 partition with these 2 (md0) formatted the raid partition ext3 and copied all the files from sda2.
Now,if i put as root in my boot files (fstab yaboot.conf) sda2, everything is ok the machine boot and i have access to md0 also ,instead if i select as root md0, i obtain the error that i shown you in the first post. Obviously ,if i try to boot from openfirmware with a diskette or from the disk i have the same result. Thanks again for your help, hoping to reach the solutions cause i can't complete the installation and put the machine online without the raid. [EMAIL PROTECTED] Bye Nicola Paltani
