You'll need the appropriate SCSI modules built > in (if you say =y), i.e. SCSI disk and SCSI CDROM should be built in. yes, that worked... after booting with root=/dev/sda2 and s/hda/sda/ /etc/fstab /etc/lilo.conf + lilo. didn't mount a /dev/sr0 for a loong time. So, are /dev/hd* going to disappear in a few years? iow, does it make sense to _slowly_ start to migrate to /dev/sd*? The problem is there's no plan B in case of any troubles except rename everything back again to boot an old kernel. -- Frank
