If you have a recent standard kernel, it should detect the cdrom drive and load a driver for it. Mine looks like this: Aug 31 11:03:16 whitewave kernel: scsi 5:0:0:0: CD-ROM PLEXTOR DVDR PX-712A 1.03 PQ: 0 ANSI: 5 Aug 31 11:03:17 whitewave kernel: sr0: scsi3-mmc drive: 125x/125x writer cd/rw xa/form2 cdda tray Aug 31 11:03:17 whitewave kernel: Uniform CD-ROM driver Revision: 3.20 There may be other unrelated lines between these lines in the messages file. Once you've verified that the kernel sees your drive and is loading a driver, you can create inode entry in /dev with something like this: cd /dev ./MAKEDEV sr Then you can create a symlink to /dev/cdrom ln -s ./sr0 cdrom Unless your system is screwed up in some other way, my sense is that this should work. Otherwise you can use mknod to create the device. nataraj -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
