/initramfs-2.6.32-131.0.15.e16.x86_64.img Which three statements are true about the
behavior and configuration of GRUB on this system?
A.
Each kernel must have an initramfs that matches the version of the kernel.
B.
Because there is an Unbreakable Enterprise Kernel installed, it must be the default
kernel listed as shown by the default=0 directive.
C.
The initrd directive specifies the initamfs, an initial root filesystem in RAM, allowing
access to block device modules to mount the real root filesystem.
D.
(hd0, 0) represents the first partition on the first drive detected by the BIOS.
E.
The root directive specifies an initial root filesystem, allowing access to block device
modules to mount the real root filesystem on disk.
F.
The hiddenmenu directive hides the GRUB menu only for 5 seconds after which it
becomes visible again.
