I need an ASSEMBLER tool.

I need to switch processor from protected mode to real mode.

I need to copy the first 512 bytes of First Sector of first drive (it's an SSD now) to 0000:07c0 and JMP to that location.

In effect I need to boot Grub2 from Linux by-passing BIOS POST to save a few seconds in sudo reboot.

Any ideas?
