Noted. I will proceed after having the OS fixed. HELP My OS crashed while playing around to install the burner. Last modification made /etc/devfsd.conf umcomment following line Create /dev/cdrw for the first cdrom on the scsi bus (remark : /dev/scsi found) type `sync;halt' and then hit reset It looks like you messed up your devfs, Hopefully your single usermode is still working. if you couldn't find your grub.conf, that means your probably using lilo! So assuming that this might work -- To get into single user mode - When you boot your computer you should see the lilo prompt and then after a preset time your computer should boot linux(if no prompt hold shift while booting). when you see the lilo: prompt hit tab it will give you a list of OS's to boot. usually Linux is called 'linux' then type 'linux 1' this tells lilo to boot linux in init level 1, which is single user mode. 3 is multi user, and 5 is usually XDM Once your in, try to undo your changes. If that doesn't work use the gentoo basic CD to boot into rescue mode. then at a prompt mount your root fs into a new directory then do the changes. i.e mkdir /mnt/linux mount -t (ext2/3/reiserfs) /dev/hda1 /mnt/linux vi /mnt/linux/etc/devfs.conf let me know if this helps.

Re: [gentoo-user] (URGENT) Installing CD Burner question
Second thought /boot doesn't get mounted automatically so you might find the grub.conf . So you might be using grub. Easy way to tell is grub is usually graphical which lilo is text based. If you are using grub highlight the OS, then hit 'e' as in edit then select the line beginning with kernel= hit 'e' as in edit again. Add a one '1' to the end of the line. then hit 'b' as in boot, to boot the changes -- [EMAIL PROTECTED] mailing list
