Passing the proper console parameters to the kernel. 2. Configuring the grub menu system to redirect to the proper console. 3. Removing any splash images that would prevent the proper serial-console display. Add the following two lines to the file /etc/grub.conf: serial --unit=1 --speed=9600 terminal serial console Adding these two lines sets up your serial port or your KVM as your grub console so that you can remotely or locally select a boot image from the grub menu. Comment out or remove the following line from the file /etc/grub.conf: splashimage=(hd0,1)/boot/grub/splash.xpm.gz Removing the splashimage line allows for greater compatibility during your serial connection; with this line removed, the splash image will not prevent the proper grub menu from displaying.

As the file changes, the in-core inode is updated usually more often than the on-disk copy. And the in-core inode has a few extra fields that are only needed while the file is opened.
