The drive worked with boot.iso CD where I did an NFS install (see an earlier thread). The Fedora 7 DVD was purchased. I have not run yum update yet. It can take a long time on dialup. GRUB menu shows: Fedora (2.6.20-2925.9.fc7xen) and Fedora-base (2.6.21-1.3194.fc7) This problem happens when booting to either. On our system I would retain the Xen kernel to play with virtualization, but on the system that I'm setting up the base kernel is all that is needed. I have deliberately avoided toying with different kernels, or even updating the kernel for that matter, until my knowledge of Linux grows some more. I still haven't got ftape working with FC6 yet, it needs kernel modules being compiled as I recall. I suppose that I don't need to now with the new DVD burner. I'll have a closer look on Fedora Forum, thanks. -- Regards Simon
