What would be the recommended way of upgrading from the /dev/hd to /dev/sd then? I have held back doing this because I didn't have the time to mess about with it. If I were to configure a new kernel without legacy ATA drivers, how would I know what my devices will be seen as in advance, so that I can change my /etc/fstab before I reboot? -- Regards, Mick
