Thanks for the reply; I booted the server (running with a previous install) with a regular CD in the usb cdrom. the OS recognizes the cdrom as /dev/scd0. It is in /etc/fstab as /dev/scd0 /media/cdrecorder auto pamconsole,exec,noauto,managed 0 0 Yet if I use "ks=/dev/scd0" I get; "loading USB storage driver" So it got that part correct... Then I get "Error opening kickstart file (null): Bad Address" It seems as though the BIOS is possibly not releasing the connection to the usb cdrom, so it is busy? Which might explain why pulling the plug and reinserting it works? Gerald
