How to: Simple Way to add UEFI to alphaOS ISO

[ndrancs]

Hi all

Ok, I'll tell you how i make UEFI ISO.
Here's the steps I did:

- Extract main ISO to, example: /mnt/home/ISO which is ext4 partition
- Delete/rename this file: ldlinux.c32 and syslinux.cfg
- Download and extract my uefi tools to /mnt/home/ISO
- Open Terminal in /mnt/home/
- type it in terminal, i use xorriso to make iso, so if use mkisofs please use latest version that support uefi

Code: Select all

# xorriso -as mkisofs -rock -omit-version-number -disable-deep-relocation -joliet -allow-leading-dots -volid "alphat64" -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot --efi-boot efiboot.img -no-emul-boot -o AlphaT64_14.5.iso ISO

and use isohybrid command to make ISO bootable in uefi machine

Code: Select all

# isohybrid -u AlphaT64_14.5.iso

and done

Note:
Please edit isolinux.cfg and grub.cfg, adjust to alphaOS boot parameters

Thanks for this guide!

I couldn't get mkisofs to work with UEFI, so added xorriso and required dependencies. Packages changed:
-cdrkit-1.1.11-3-x86_64.pkg.tar.xz
+libburn-1.3.2-1-x86_64.pkg.tar.xz
+libisoburn-1.3.2-3-x86_64.pkg.tar.xz
+libisofs-1.3.2-1-x86_64.pkg.tar.xz

I will upload small iso, without extra.sb included so you can test. What I've tried so far iso works in virtualbox and when written to USB.

I have tested this iso, and this is the result:
The iso is fail to boot in uefi machine, then i check the iso, the /EFI/grub2/grub2.efi and /grub.cfg is missing. Maybe you delete this files to save some space.
Ok if you want to save some space, you can try this:
- recompile the kernel with uefi stub config enable, so the kernel can be loaded directly in rEFInd.efi (uefi boot manager), with current kernel this is not possible.
- add this code to /EFI/boot/refind.conf

Code: Select all

menuentry "alphaOS" {
   icon /EFI/boot/icons/os_linux.icns
   loader /alphaos/boot/vmlinuz
   initrd /alphaos/boot/initrfs.img
   options "from=/alphaos"
}
