nized by the operating system. The vendor typically releases a Driver Update Disk
with the xed or updated version of the required driver.
In both cases you need to access the installed system in the rescue mode and x
the kernel related problem, otherwise the system may fail to boot correctly:
1 Boot from the openSUSE installation media.
2 If you are recovering after a faulty kernel update, skip this step. If you need
to use a driver update disk (DUD), press [F6] to load the driver update after
the boot menu appears, and choose the path or URL to the driver update and
conrm with Yes.
3 Choose Rescue System from the boot menu and press [Enter]. If you chose
to use DUD, you will be asked to specify where the driver update is stored.
4
Enter root at the Rescue: prompt. A password is not required.
5 Manually mount the target system and “change root” into the new environ-
ment. For more information, see Section “Accessing the Installed System”
(page 263).
6 If using DUD, install/reinstall/update the faulty device driver package. Always
make sure the installed kernel version exactly matches the version of the
driver you are installing.
If xing faulty kernel update installation, you can install the original kernel
from the installation media with the following procedure.
6a
Identify your DVD device with hwinfo --cdrom and mount it with
mount /dev/sr0 /mnt.
6b Navigate to the directory where your kernel les are stored on the
DVD, for example cd /mnt/suse/x86_64/.
6c
Install required kernel-*, kernel-*-base, and kernel-*-extra pack-
ages of your avor with the rpm -i command.
6d After the installation nishes, check that a new menu entry relevant
for the newly installed kernel was added to the boot loader congu-
ration le (/boot/grub/menu.lst for grub).
7 Update conguration les and reinitialize the boot loader if needed. For more
information, see Section “Modifying and Reinstalling the Boot Loader”
(page 264)
8 Remove any bootable media from the system drive and reboot.
