X86 partition tables

Hi,

Couple of questions about partition tables on x86 hardware.

Do most x86 machines (an APUv6 w/ Coreboot in my case, and a Qemu/KVM VM with Bochs as well) support GPT in BIOS (CGM or whatever)?

And what are the steps on a live system to (1) convert the MBR partition table to MBR, and (2) reinstall grub?

Thanks,

-Philip
