Installation of Fedora 21 on clean APM Mustang

Last week I wrote a blog post about installing Fedora 21 on APM Mustang with use of already existing GRUB. But let’s consider it cheating ;D

This time I am going to write how to install on fresh clean APM Mustang. I am assuming UEFI firmware not U-Boot so it you use latter then follow Updating to UEFI page on Fedora wiki.


  • DVD drive
  • DVD disk with Fedora 21 AArch64 DVD image written to it
  • PCI Express SATA controller
  • USB thumb drive (128MB is enough)
  • APM Mustang with UEFI
  • serial cable connected to Mustang and other computer
  • Ethernet cable to get network on Mustang
  • VNC viewer to control installation (not needed but recommended)

First step is preparing USB thumbdrive. Create GPT partition type ‘ef00’ (EFI System), format it as FAT and copy “/EFI” and “/images” directories from DVD. Then plug it into one of USB ports on back of Mustang. Why only those files instead of whole image? Reason is simple: UEFI knows how to handle USB but Linux kernel does not ;(

Put PCI Express SATA controller into PCIe slot and connect DVD drive to it. This is needed cause X-Gene SATA controller is unable to handle DVD drive — see bug #1150676. Put Fedora installation disk into drive.

Now reboot Mustang and wait for UEFI prompt (you may press a key before it goes for PXE boot):

[b] Shell
[c] Reboot
[d] Shutdown
Start: ?

Select “Shell” option. After few seconds UEFI will present you list of recognized filesystems and block devices (I have one clean hard drive connected):

UEFI Interactive Shell v2.0
UEFI v2.40 (X-Gene Mustang Board EFI Aug 21 2014 13:43:15, 0x00000000)

     BLK6: Alias(s):
     BLK5: Alias(s):
     BLK0: Alias(s):
     BLK1: Alias(s):

Enter shell and then enter one command (you can use key for completion): “fs0:\EFI\BOOT\BOOTAA64.efi” to boot Grub from USB:

Install Fedora-Server 21_Alpha
Test this media & install Fedora-Server 21_Alpha
Troubleshooting -->

Use the  and  keys to change the selection.
Press 'e' to edit the selected item, or 'c' for a command prompt.

Select first option and then it is standard Fedora installation. Anaconda starts and suggests using VNC to control installation as serial line interface lacks many options.

Fedora installer

Installation takes several minutes. But there is another bug there: unable to add bootloader entry into EFI so we have to fix it before final release.


But bootloader itself is loaded so after reboot we land in UEFI shell again. This time need to run “fs0:\EFI\fedora\grubaa64.efi” and there it goes: fresh Fedora 21 installation.

  1. This is much like how I did my install – but I didn’t think of a sata card (I didn’t know about the bug!) – I created an sda disk image of the installer and booted off that drive to do the install. I’ll share the tar file to extract to a fat32 partition if it seems useful.

    Thanks for your posts – they have helped me quite a bit!


    1. Doing installation with extracting install image to hard drive is popular method. But in such case I would rather take thumb drive from my article and do network install like described in my previous post.
