C'e' appena stata una discussione su grub riguardante il parametro
root. Qualcuno ha gia' postato dal manuale di grub:


root 
 - Command: root device [hdbias]
      Set the current "root device" to the device DEVICE, then attempt
      to mount it to get the partition size (for passing the partition
      descriptor in ES:ESI', used by some chain-loaded boot loaders),
      the BSD drive-type (for booting BSD kernels using their native
      boot format), and correctly determine the PC partition where a BSD
      sub-partition is located. The optional HDBIAS parameter is a
      number to tell a BSD kernel how many BIOS drive numbers are on
      controllers before the current one. For example, if there is an
      IDE disk and a SCSI disk, and your FreeBSD root partition is on
     the SCSI disk, then use a 1' for HDBIAS.

Che abbia qualcosa a che vedere col tuo problema?

ciao
