Perform the following procedure. Procedure 1 Use the following command to check which kernel is being used. # uname -r 2 Backup the existing initial RAM disk image file, then create a new initial RAM disk image file. Example: For kernel version el5 # cp /boot/initrd el5.img /boot/initrd e15.img.bak # mkinitrd -f /boot/initrd e15_new.img el5 New initial RAM disk image file name 3 Set the boot loader.
