    7.5.*Installing from DVD/CD-ROM
    That's a good suggestion, definitely try that first. I remember having to do that, back in the day.

    the system doesn't detect the DVD writer.
    In CentOS 5 the dvd writer is
    Code:
    /dev/hdb
    . if i undestrand correctly the file suggest to boot with a "link" on /dev/hd* (/dev/hdb in my case) but i don't have any hd*. This said, will i try to boot "linking" on /dev/hdb though i don't have any /dev/hd* device?

    I might not have understood, in this case can you explain me in a simpler way? Thanks

    EDIT: i see in the configuration menu before compile the kernel ( make menuconfig) that it's possible to use old configurations. It's possible to extract the configuration of the Centos 5 2.6.18 kernel and load it on the new kernel? How can i extract the configuration of the centos' kernel?

    The udev daemon is supposed to take care of creating block devices for you "on the fly"...but if that is not the case, you can create it yourself (as root):
    Code:
    mknod /dev/hdb b 3 64
    Some distros come with a script, /sbin/MAKEDEV. You would cd into /dev and do:
    Code:
    /sbin/MAKEDEV hdb
    but the first command should be all you need.

    You can get it from the source RPM as in my previous instructions, or get it from the binary RPM, too, e.g.:
    Code:
    wget http://vault.centos.org/5.6/os/i386/CentOS/kernel-2.6.18-238.el5.i686.rpm
    rpm2cpio < kernel-2.6.18-238.el5.i686.rpm > kernel-2.6.18-238.el5.i686.cpio
    mkdir kernel-2.6.18
    cd kernel-2.6.18
    cpio -idv < ../kernel-2.6.18-238.el5.i686.cpio
    ls -l boot/config-2.6.18-238.el5
    cp boot/config-2.6.18-238.el5 /path/to/new/kernel-2.6.18/.config
