This post demonstrates how to use both the new efivarfs filesystem and older efivars mechanism to create, read, write and delete (U)EFI variables. The (U)EFI Shell has been around one form or another for nearly 15 years. Recenly I looked at Shell startup options and found that the relevant code in the Shell was badly broken and could never have worked. This post details my findings and solutions. In this post, I examine how to directly boot Fedora 17 from UEFI firmware. I also discuss a number of non volatile variables which the Linux kernel can create during an kernel crash. 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. |
