Jul 09, 2015  Ubuntu 32/64-bit 18.04 ISO Desktop and Server Free Download is the latest version for Linux. It is the full offline installer standalone setup direct single click download of Ubuntu OS. Ubuntu developer Phillip Susi has proposed adding 32-bit UEFI support to the main Ubuntu Linux image. While this has been proposed in the past and then to do a separate spin with only legacy BIOS support, what he added is then to do only a simple net-install image of Ubuntu 32-bit for users of these older systems. The 2007 and 2008 'Macbooks' have 64 bit core2 duo processors in them, but still had a 32 bit EFI which is sorta like bios and is what is needed for the OS to boot for installation.

I have a Intel BayTrial Z3735D tablet which comes with a 32bit UEFI BIOS.After some search I've found that most linux distro don't come with a 32bit efi file.

How can I insert one (or build a new ISO)

According tohttps://wiki.archlinux.org/index.php/HCL/Firmwares/UEFI#Intel_Atom_SoC_Bay_Trail, this should be possible.

The Baytrail tablets run a 64b processor and a 32b EFI, for reasons best known to Intel.

Grub2 (compiled for 32b EFI) will start a 64b UEFI operating system from a 32b EFI.

Just like a 64b or 32b CPU processor calling into a traditional 16b BIOS, a thunk is needed in the operating system to marshal the arguments from 64b to 32b, change the processor mode, call the firmware, and then restore the processor mode and marshal the arguments from 32b to 64b. A x86-64 Linux kernel built with the option CONFIG_EFI_MIXED=y includes such a thunk to allow the x86-64 kernel to call to a i686 EFI.

At this point in time there is no thunk for AMD's AtomBIOS, and thus the 'radeon' module fails. This isn't an issue for the Baytrail tablets, as they use the Intel GPU.

I would look at the Ubuntu operating system when considering Baytrail, as Fedora is yet to build their stock kernels with CONFIG_EFI_MIXED=y. Use a USB stick like Super Grub2 Disk to get to the Grub2 (32b) command line and then load and run the x86-64 installer kernel from the Grub2 command line. Once you have installed Ubuntu go back and install Grub2 32b bootloader to the EFI partition by hand and remove the Grub2 64b bootloader.

The lack of advanced video driver is a showstopper for the MacBookPro2,2 as it uses the AMD Radeon X1600. Linux can boot using the EFI 'UGA' driver (roughly equivalent to using the VESA option in BIOS-land). But the result is so much overhead that then fans run at full rate continually. Note that the 'radeon' module copies the AtomBIOS contents into RAM, and thus a small change to the driver to allow the AtomBIOS to be loaded from disk is a path to solving this issue. Probably the best approach on a early Mac is to run a 32b operating system, although most of the popular distributions do not support EFI in their i686 32b builds.

This page might be of help, titled: Linux on UEFI:A Quick Installation Guide. Specifically this section:

Ensure that you're using a distribution that's the right bit depth — EFI runs boot loaders that are the same bit depth as the EFI itself. This is normally 64-bit for modern computers, although the first couple generations of Intel-based Macs and a handful of obscure computers use 32-bit EFIs. I have yet to encounter a 32-bit Linux distribution that officially supports EFI, although it is possible to add a 32-bit EFI boot loader to 32-bit distributions. (My Managing EFI Boot Loaders for Linux covers boot loaders generally, and understanding those principles may enable you to modify a 32-bit distribution's installer, although that's not a task for a beginner.) Installing a 32-bit Linux distribution on a computer with a 64-bit EFI is difficult at best, and I don't describe the process here; you should use a 64-bit distribution on a computer with a 64-bit EFI.

So given this I'd probably shy away from attempting to use a 64-bit distro and adding my own 32-bit UEFI loader to start. I'd find a 32-bit distro. There are options here, mainly in the embedded space.

If you're determined and want to do this @RodSmith has provided details in this AskUbuntu Q&A titled: 32-Bit UEFI Boot Support.

I had this problem with a Packard Bell Easynote, after a lot of research I have discovered that Sparky Linux 32bit does actually support 32bit efi. Any of the 586 versions seem to work. I have successfully installed the LDXE version.

Not stable enough to survive certain updates

I expected that it could be installed into a USB pendrive as a good alternative to a persistent live system, possible to update and upgrade without limits. But unfortunately a current update involving a new kernel and updating grub will make it fail to boot. So this system is not stable enough to survive certain updates. It is good only as an illustration of a method to make a bootable drive in UEFI as well as BIOS mode.

If you want a stable portable system, that boots in UEFI mode as well as BIOS/CSM mode, and in 64-bit as well as 32-bit computers, you can try One pendrive for all PC (Intel/AMD) computers. If you want a pendrive with a live and an installed system, you can try A new and so far successful attempt to create a stable portable system, that works in UEFI and BIOS mode.

Detailed instructions

Stable alternative 1

There are links to instructions how to make an installed system (typically in a USB pendrive) that works with UEFI and BIOS, and is small enough to work in an undersized 16 GB pendrive. This system is created from Ubuntu 16.04 LTS 'Xenial' amd64 ('gamma' because it is beyond beta), and was simplified compared to the previous methods to make a stable installed system for UEFI and BIOS mode.

See this link to the sub-page: /stable-alternative

This link shows the post in an Ubuntu Forums tutorial, where the method was published:

Compressed image file

It is straight-forward to install from a compressed image file from with mkusb or mkusb-nox. Some tools may not work with compressed images of such large files. I tried in Lubuntu Xenial daily to restore disk image with gnome-disks alias Disks, but it considered the size to be 3.5 GB, when it was 12 GB, so the image was truncated, Bug #1571255

After this cloning operation you should run gpt-fix in order to match the gpt data to the current drive size.

Description of the short-cut to make an installed system (typically in a USB pendrive) that works with UEFI and BIOS from a compressed image file:

Download source 1

Download the following compressed image files from

https://phillw.net/isos/linux-tools/uefi-n-bios

Remember to check with md5sum, that the download of the compressed image file was successful.

Download source 2

Download the following compressed image files from

https://drive.google.com/open?id=0BzX-18u3W1sQUXI2YV95dHJxVlE

Torrent file

You can download a torrent file in order to get a compressed image file.

The dd_text_16.04-UEFI-n-BIOS compressed image file was made up to date, and a torrent file was uploaded in January 2017. This is the main choice, if you want to start with a light-weight system and install your own selection of program packages - desktop packages, server packages and application packages.

dd_text_16.04-UEFI-n-BIOS_2017-01-15_intel-4-pendrive-7.8GB.img.xz.torrent

There is a special version of the UEFI-n-BIOS system with the new dus installer. It can be used as a general purpose installed system too, in USB pendrives, memory cards (and also in SSDs and HDDs). Download the following torrent file, and use it to get the compressed image file.

dd_dus-lxde_16.04-UEFI-n-BIOS_2016-12-12_intel-4-pendrive-7.8GB.img.xz.torrent

User and password

in Linux

The target drive will be overwritten. Double-check which is the target drive, the drive you want to install into!

Use mkusb to install the system from the compressed image file.

See https://help.ubuntu.com/community/mkusb

gpt_fix in mkusb

The GUID partition table, GPT, is fixed automatically, if you use mkusb 10.6.6 or a newer version to install from these compressed image files. The functions gpt_zap and gpt_fix are built into mkusb.

If you use other tools, you need gpt-fix or to fix the GPT manually with gdisk.

in Windows

Check the download and clone the image in Windows according to the following page

Win32DiskImager/compressed-image_2_USB-or-SD

or according to this summary:

Download the following help programs

http://www.md5summer.org

https://www.7-zip.org

https://sourceforge.net/projects/win32diskimager

First check that the download was successful with md5summer according to the file md5sums.txt.asc.

Ubuntu Server 32 Bit Iso

Next extract the image file with 7-zip (It is also possible with winzip)

from dd_Ubuntu_16.04-gamma-UEFI-n-BIOS-4-pendrive-12GB.img.xz

to dd_Ubuntu_16.04-gamma-UEFI-n-BIOS-4-pendrive-12GB.img

The target drive will be overwritten. Double-check which is the target drive, the drive you want to install into!

Then write the extracted image file (without the ending gz) with win32diskimager

Win32diskimager looks for img files.

gpt-fix

After this cloning operation you should run gpt-fix in order to match the gpt data to the current drive size (unless you are using mkusb version 10.6.6 or newer versions of mkusb).

See more details at /stable-alternative#gpt-fix

Final system tweaks

Decrease wear for a pendrive

Add the mount option noatime in /etc/fstab

Do not copy this line. Use your own data, only add noatime,

Turn off journaling

where x is the drive letter and y is the partition number of the root partition, for example /dev/sda3.

Maybe remove swap

It is also possible to remove the swap partition and the swap entry in /etc/fstab in order to avoid wear due to swapping.

Move swap and grow root partitions

Move the swap partition and grow the root partition to use the whole drive. See this link

Login and password

When you have installed these systems from a compressed image file, and you reboot, you log in with the following user and password

It is a good idea to change the password.

If you want a stable portable system, that boots in UEFI mode as well as BIOS/CSM mode, and in 64-bit as well as 32-bit computers, you can try One pendrive for all PC (Intel/AMD) computers. If you want a pendrive with a live and an installed system, you can try A new and so far successful attempt to create a stable portable system, that works in UEFI and BIOS mode

It might be a good idea to try various systems and methods before deciding what to install. Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, ..) before installing it
