real_root=/dev/sda3 deve stare sulla stessa riga di kernel

>> Block device /dev/sda3 is not a valid root device...
The root block device is unspecified or not detected.
Please specify a device to boot, or "shell" fora a shell..

Mai il kernel é partito?
Se si, riesci a vedere in mezzo alle varie scritte quella che identifica il disco?

come promesso.. sono tornato il giorno dopo.:roll:

root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda3

non ho mai visto quella sintassi.
sul manuale del mio grub (0.94) non esiste proprio il tag real_root

fai una prova, metti root=/dev/sda3 e togli real_root

------------------------

bene.. adesso cambia totalmente il messaggio:

kernel panic...

Quello serve per chi usa il framebuffer gentoo, e quindi ha una prima root su ramdisk...

Non c'é nel manuale di grub perché é un parametro da passare al kernel (che poi lo farà "galleggiare" fino all'initi )
