Re: [solved] Boot GPT disk in UEFI mode (Phoenix SecureCore Tiano)

Ok, just adding this here for anyone else who might wind up here looking for information like I did....
On a ThinkPad T520 UEFI version 8AET46 (1.26), I wrote a GPT partition table and set up the directories for EFISTUB as documented on the wiki ( https://wiki.archlinux.org/index.php/UE … up_EFISTUB ) and changed my UEFI/BIOS to boot only UEFI.
I used a flash drive formatted to FAT32 with the Shell_Full.efi linked above ( https://edk2.svn.sourceforge.net/svnroo … l_Full.efi ) to boot my arch install under UEFI
after I booted, I ran

 # echo "root=/dev/disk/by-label/zyanya-root ro rootfstype=ext4 add_efi_memmap init=/bin/systemd initrd=\\EFI\\arch\\initramfs-linux.img" | iconv -f ascii -t ucs2 | efibootmgr --create --gpt --disk /dev/sda --part 4 --label "Archlinux (EFISTUB systemd)" --loader "\\EFI\\arch\\vmlinuz-linux.efi" --append-binary-args - 

and proceeded to boot my system.  (Note, I had configured systemd before starting this.  Make sure to modify the code above before you run it! Your disk label, partition number, etc are very likely to be different!)

Took me a good 3-4 hours to read all the documentation and figure out what I did wrong a couple times, but I can boot from full-off to login prompt in 12 seconds now.

Just to say: most of what's said about Arch in this thread is no longer true; the problem with which the thread is concerned is (probably) not the real problem and what is (probably) the real problem is now covered in the wiki (although the solution described here also works).

Moreover, this thread was concerned with a fairly specific firmware which differs from the one in ArcherSeven's post so it is unclear either that the problem described in this thread would apply in ArcherSeven's case or that ArcherSeven's suggested solution would work in mine (even now that it is available).

Okay, I'll go with that.

Anyone who needs to, please start a new thread specific to your situation.  If you feel it is relevant, link back to this thread.

Thanks.
