Adding a 32-bit GRUB bootloader to boot and install ISOs

by
2y ago
  Many distros no longer include both 32-bit and 64-bit bootloader support. Unfortunately some hardware including most based on the relatively recent Intel Atom processor architecture won't boot 'OOTB'. Whilst I wrote 'isorespin.sh' and 'isorespinner.sh' in part to address this issue I restricted their functionality to the Ubuntu 'family' of ISOs for support purposes. One of the most frequest questions I have been asked is 'can you add support for <insert distro> ISOs?'. Unfortunately distros, even those based on or derived from Ubuntu, are often built with different directory stru ..read more

Customizing Ubuntu ISOs: Documentation and examples of how to use 'isorespinner.sh'

  isorespinner.sh This script is a ​progression of 'isorespin.sh'. Whilst 'isorespin' was created to support Ubuntu and similar Linux distributions on mini PCs, some of the functionality that was developed is now unused. Additionally with ​Canonical now trialling a new ​Ubuntu ​desktop installer and the ISO using a new multi-layer filesystem, rather than hack the ​earlier code to coerce compatibility I'​ve​ developed a new script ​which I've called ​'isorespinner.sh' ​which provides the most useful features and ​addresses the functionality that is ​now relevant to​ ​r ..read more

Canonical have announced the release of Ubuntu 22.04 LTS (Jammy Jellyfish)

For the last few years I've respun various ISOs to support running Ubuntu, Ubuntu flavours and Ubuntu-based distros on mini PCs by specifically addressing the issue of those devices that use restrictive bootloaders including 32-bit GRUB. I've relied on donations to support my work and cover development and storage costs. Recently these have been few and far between indicating that the demand for such ISOs is not there. As a result I'm reducing the number of ISOs I provide and only offer some examples of how my 'isorespinner.sh' script works. With Canonical announcing the latest release o ..read more

If things don't change, things will stay as they are.

  The 'canary' ISO for Ubuntu 22.04 (Jammy Jellyfish) introduces the new Ubuntu Desktop installer which uses 'subiquity' as a backend and 'Flutter' for the UI. Rather than hack 'isorespin.sh' to coerce compatibility I'm developing a new script which takes the most useful features and targets functionality that is more relevent to current usage. Despite plus ça change, plus c'est la même chose (the more things change, the more they stay the same) I thought it best to give the script a new name: 'isorespinner.sh'. More to come. “If things don't change, things will stay as they are ..read more

First look at SteamOS 3

  Having downloaded the Steam Deck recovery image and written to a USB using 'Rufus', I was surprised that booting on various AMD mini PCs has so far been unsuccessful whereas after just a few tweaks it successfully booted on a couple of different Intel NUCs.  Installation was easy however rebooting again needed tweaks to get to a SteamOS 3 desktop. Package installation was hindered by trust issues related to signatures but eventually I was able to install 'neofetch' as an example. However 'gaming' is limited as most games baulk at the lack of a suitable graphics capability an ..read more

Following news of the GRUB2 Secure Boot Bypass 2021 and as a result of Google's security changes on Google Drive together with the first daily build's from Canonical of Ubuntu 21.10 (impish) and point releases for 20.04.3 and 18.04.6 I've updated my ‘isorespin.sh‘ script and respun some ISOs suitable for Intel Atom and Intel Apollo Lake devices. Note that support for 21.10 (impish) is not finalized as the release is still under development so respinning will be experimental at this stage. However due to a new compression tool being used an additional package 'zstd' will need to be i ..read more

I've previously looked at Windows and Linux performance on the NUC11PHKi7C Enthusiast Phantom Canyon which is Intel’s latest NUC 11 flagship product specifically targeting gamers as it includes an NVIDIA RTX 2060 GPU. One usage aspect I didn't test was virtualization and this brief article looks at the performance running VirtualBox and WSL2 on the NUC11PHKi7C and comparing it to Intel’s previous NUC with a discrete GPU: the NUC 9 Extreme Ghost Canyon. Hardware Overview For the NUC 9 Extreme I’ve using a NUC9i7QNX model and I purchased both the NUC11PHKi7C and NUC9i7QNX as barebon ..read more
