I was given a HP Stream 7 tablet yesterday, Originally it ran Windows 8 - Which must have been highly optimized for this. It only has 1gb ram, and 32gb storage. With an #Intel #Atom Z3235G quad core. So I tried to install #linux on it. The biggest frustration I'm having with it thou, is the #EFI only supports #32bit boot. And I've only found #Antix to actually install, but I can't get wifi to work, or sound. I think #Lubuntu might work but it fails at installing grub i386.

Во времена #EFI & #UEFI этот самый #GRUB уже и не нужен.
Во-первых, полно и других разнообразных UEFI boot manager'ов.

Во-вторых, не особо то они и нужны вообще как класс. Компьютер можно загружать и напрямую через EFI-stub ядра ОС, образы которых давно собираются как EFI-приложения (раз и два).
Т.е. надо идти в настройки UEFI материнской платы и смотреть загрузочные записи, хранящиеся в #NVRAM — дописывать туда все те параметры\аргументы, которые UEFI при старте компа будет подставлять в качестве аргументов командной строки. Так же как и GRUB или другой boot manager грузящий vmlinuz-файл.

Цивилизованный старт
Использовать то, что было известно как #gummiboot, а теперь стало называться #systemd-boot. Там вполне удобные текстовые файлы в /boot/loader/entries/... через которые можно передать нужные значения и аргументы в переменные. Например такие как используются для #LUKS разделов:

options	rd.luks.options=password-echo=no
options	rd.luks.data=UUID=/dev/disk/by-id/nvme-VENDOR-partN
options	rd.luks.name=UUID=my-enc-swap
options	resume=/dev/mapper/my-enc-swap
options	rd.luks.data=UUID2=/dev/disk/by-id/nvme-VENDOR-partY
options	rd.luks.name=UUID2=my-enc-root
options	root=/dev/mapper/my-enc-root

Не обязательно задавать таким образом по одной опции на строке, можно устраивать свалку пихая всё в одну большую строку.

Комментарий №1
В данном примере, это когда swap идёт не файлом, а отдельным разделом на диске, такое размещение упрощает использование swap для hibernate.

Комментарий №2
Все эти LUKS-опции не обязательно указывать при каждом запуске системы в /boot/loader/entries/... файлах или через загрузочные записи UEFI внутри #NVRAM
Можно прописать всё это сопоставление и через файл /etc/crypttab.initramfs перед генерацией\созданием #initramfs образа.

When you have workflows like mine it's unreasonable to have dozens of slow usb sticks ready to dd distributions on. It's cumbersome to index / manage so many slow devices. USB sticks also live much shorter than 2.5" SSD's here. I've had some working for years (mostly reads) And some fail in weeks after many writes, for me unreliable storage devices

Ventoy has become a vital tool ISO mangagement and booting for me, since I can dump bootable ISO''s of most OS's on SATA SSD's, structure the ISO's in logical directory flows and have a librarian oversight of them

I can mount the SSD via an USB3 tray and thus move hundreds of ISO's around without a fuzz. I use 2.5" SATA SSD's because they are large enough in physical dimensions to be handled easily and I can write and ID on them with a marker. They can also live for years of R/W operations without failing.

Ventoy can easily boot a variety ISO/WIM/IMG/VHD(x)/EFI of OS's which are of various origin.
>> Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files

When a ISO++ fails to boot, you need to make the coder(s) of Ventoy aware of it, and chances are that in the next update, scripts have been finetuned so Ventoy can handle that family of files also.

Ventoy is easy to use update run & maintain for the end user.

Try Ventoy

For days I've been trying to get the integrated #GPU on my #MacBook working on #Linux. But it doesn't show up anywhere in the system. It's like it is not there at all.

Turns out: it in fact isn't. If you boot anything other than #macOS the #EFI itself turns the integrated GPU off leaving only the dedicated GPU.

This little EFI program turns it back on again:

Photograph of MiniPC bios recovery POST screen

#EFI #UEFI #BIOS #recovery #POST #Asus #MiniPC #hardware #NUC #technology #BLKNUC7i3DNH2E

For me the method described on the Asus NUC support section worked

The miniPC refused to boot after a BIOS settings regarding display / power were modified.

Contrary to my logical thinking, miniPC's made by Intel, refuse to follow standard BIOS UEFI reset methods, of normal motherboards, which involve setting a cmos jumper then clearing the faulty settings, after default setting boot

This machine wanted me to
* download it's (current) UEFI (BIOS)
* create a fat32 partition on a USB drive (I used SATA USB SSD)
* unzip the package setting the encapsulated file (.bio) in the root dir of the partition
* remove the security jumper (yellow)
* connect & power the USB SATA SSD
* power up the miniPC (NUC)
* wait for the machine to read the encapsulated BIOS stop the flash sequence / countdown (30 secs)
* choose theBIOS entry option
* after reboot cycle reset the BIOS to default settings
* disable TPM and Intel platfor rubbish
* reboot then reconfigure the BIOS
* check all settings

Without my Android & later my SBC I would have been stuck

New blog post from me: I Stubbed My Bootloader And Lived To Tell The Tale

https://martinh.net/hacks/zero-boot/

It all started when a man with a gun sent my laptop flying, while we were travelling at over 100 miles per hour…

#MildPeril #Linux #GRUB #EFI #UEFI #EFIBootStub #Arch #btw

Say goodbye to complex #boot #configs. #Tumbleweed’s new default, #GRUB2-BLS, means no config generation, easier encryption with #systemd tools, and a streamlined #EFI setup. Full-disk encryption with #TPM2? Now just a few clicks. #openSUSE https://news.opensuse.org/2025/11/13/tw-grub2-bls/

I think what the #OpenBSD installer does was simply create the openbsd directory in #EFI partition and copy boot.efi files there. Additionally it probably also copy these files to the boot dierectory there, which makes openbsd the default #UEFI boot entry. However, if you want to change boot entry orders, for example for your four different systems, you will have to go to BIOS settings. OpenBSD is not able to handle that, #efibootmgr in #Linux and #FreeBSD is for this task.

These always crack me up. #itfailsusa #efi #Airports

I should find the picture that I took of one of the ordering terminals in #Argos the other day that was stuck at the EFI Shell prompt.

Recently started having rEFInd (actually, I think the EFI BTRFS driver) fail to load the kernel ("Not Found"). Infuriating since the kernel works in other filesystems (even BTRFS ones!) and some kernels work fine.

Not sure how to debug.
