In this post I discuss the differences between how UEFI hands off memory to the Linux Kernel and how old-fashioned BIOSes handled off memory via E820.

This post discusses the requirement for a GPT BIOS Boot Partition by GRUB2 in order to boot a BIOS-based system. This post discusses how to upgrade your Fedora 16 system from a MBR partitioned boot disk booted using GRUB Legacy to a GPT partitioned disk booted using GRUB2. With the release of Fedora 15, I decided to have another look at the state of UEFI booting Fedora using GRUB2. In this post I show you how to build and install an UEFI version of GRUB2 which can be used to boot Fedora 15 instead of using the UEFI-enabled version of Legacy GRUB that comes with Fedora 15. This post demonstrates how to build a simple bootable image containing GRUB Legacy and run it in QEMU in either graphical or non-graphical mode. |
