How to boot kernel and bypass the BIOS
Kexec is a fastboot mechanism which allows botting linux from the context of already running kernel without going to BIOS
Check if kexec tools installed
rpm -q kexec-tools
To load a kernel, the syntax is as follows:
# kexec -l kernel-image --append="any command-line-options" --initrd=initrd-image
Easy way to boot current kernel is:
# krnl=`uname -r` ; kexec -l /boot/vmlinuz-$krnl \
--initrd=/boot/initramfs-"$krnl".img --reuse-cmdline
