It appears that Debian have the same problem. In the installation of
both Debian Lenny and CentOS 5.5, I had no problems, but appear later
using 'setup' and 'root':

But invoking GRUB with this file, it does recognize the disk:

debian-test8:~# grub --device-map=/boot/grub/device.map

Done.

However, in installations made on IDE disks, it is not necessary to do
this. What could be causing this difference?
Thanks for your replies.
