    CD/DVD drives not listed


    I had Windows XP and Suse 9.2 running in a 486 Optima MyPC.
    A toggle switch connected to the master pins of 2 40GB hard drives allowed
    either operating system to be selected for boot up.
    The Optima recently died, the 2 hard drives and selector switch have been
    located in a Dell Dimensions 8300 Bios Rev A04.
    Needless to say Windows will not start but Suse does and the data on both
    drives is viewable and Open Office 1.1 useable.
    Problem. The 2 DVD/CD drives in the Dell unit are not detected.
    How do make these drives operational?
    You will appreciate I am not too familiar with Suse Linux, having tried several
    methods I often get "You don't have permission" or similar.
    How do I change to the Top Level Permission?

    Hi and Welcome !

    You can root privileges ( top level permissions ) through su command in Terminal. But that will limit you to Terminal commands only.
    Do you know the root password? Have you tried to log in as user name root and its password? Its not recommended to log in as root in Graphical Interface though.

    Regarding CD/DVD detection problem, execute this code in Terminal :
    Code:
    su -
    hdparm -I /dev/cdrom
    hdparm -I /dev/dvd
    su command will ask for root password and note that nothing will appear on screen while typing password, not even *****. Just type correct password and hit Enter key.
    It is amazing what you can accomplish if you do not care who gets the credit.

    I presume each line is followed by a CR. Is that correct?
    Amazing that I remembered the password but
    when I enter the text specified I get
    " No such device or address"
    Both drives pop in and out and lights flash.

    Suggestions please.

    9.2 is very old. Maybe it does not support the newer hardware/BIOS?

    The above commands gave me the following responce

    "inappropriate ioctl for device"

    very puzzled
