NO, it doesn't. EFI is the replacement for the BIOS, not the partition table type. EFI required GPT, but GPT can be used in a BIOS based system.

For now, just let us know your results. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
