Bug#788532: grub-efi-ia32-bin should be shipped on install DVD
So, after a weekend of playing with this device[1], I conclude: - Debian 8 multiarch DVD includes everything necessary for a working OS installation. - To install a full Desktop environment (i.e. Gnome), an internet connection is still required. - Installing a 64bit OS with 32bit Grub is possible, but will not boot most of the time. It usually hangs after Grub's "Loading initrd..." message. I did get it to boot once or twice, but why remains a mystery. - 32bit Debian works like a charm on this device, not a single hang at boot, Gnome desktop is usable. - A lot of hardware in the device does not work: the touchscreen, wireless and Bluetooth, power management, the battery indicator, the SD card reader (internal flash is fine), both cameras, sound, volume rockers and power button - The device has a combined USB and charging port. I managed to find a suitable Y cable, so I can inject power into the device and an external USB hub while connecting keyboard, mouse, ethernet and pen drive via the hub. - I tried kernel 4.0.0-2 from sid, it works equally well, but with the same driver limitations. - A friend of mine who is familiar with Bay Trail devices suggested that the ACPI tables are most likely incomplete, making the kernel simply not see certain components, and thus failing to enumerate devices. Tough luck. - I imaged the preinstalled Windows 8.1 before wiping the flash, and succeeded in extracting the registry Hives. Maybe I can find a complete hardware list with resource assignments there. To do. - I have a driver matching the wireless chipset[2], but it doesn't work because the SDIO bus fails to enumerate anything on Linux. I'm quite certain the driver is fine, as I had it operating in a different device with the same chipset. - The device comes with a full-blown Award UEFI BIOS setup. You can configure almost every component, possibly even some that aren't there. The USB setup page mentions XHCI and OTG support, but this isn't supported officially, and the single USB port is not a USB 3.0 one. If you can provide any further help or pointers, they'd be well appreciated. For now, my priorities lie on getting wireless and the touchscreen to work. That would turn the tablet from "working" into "useful". Thanks! Ah, and I think the bug report can be closed now.

I *think* the Ubuntu guys are doing EFI on i386 these days, but I could be wrong. I've spoken to them about the details in the past. But the multiarch installer is definitely specific to Debian, and the mixed-mode EFI support in the installer exists only in Debian *yet*. I expect other distros to look into it soon-ish, and it's great to share this kind of work to help everybody. -- Steve McIntyre, Cambridge, UK.st...@einval.com Getting a SCSI chain working is perfectly simple if you remember that there must be exactly three terminations: one on one end of the cable, one on the far end, and the goat, terminated over the SCSI chain with a silver-handled knife whilst burning *black* candles. --- Anthony DeBoer -- To UNSUBSCRIBE, email to debian-cd-requ...@lists.debian.org with a subject of "unsubscribe".

Not exactly a common trail, then. :-) Well, brand new hardware that "just works" is relatively rare. I just happen to value Debian as a starting point for most of my Linux-related endeavours. Reduces configuration/customisation by much, and still manages to come without unnecessary bloat like certain other distributions.

What how where multiarch? Ok, it looks I completely missed that. Oops. And if I'm reading your blog correctly, the i386 images come with UEFI support, so that would be an option too. Except that I don't really like the idea of missing out on the advantages of amd64.

If that's the best way to get what I want, I'll give it a try. This seems pretty unique to Debian though? Ubuntu doesn't ship their i386 installers with EFI boot support, and they don't seem to have a multiarch installer either. -- To UNSUBSCRIBE, email to debian-cd-requ...@lists.debian.org with a subject of "unsubscribe".

Hi Steve >> This is actually the responsibility of the debian-cd package, >> reassigning. I did not know that, thank you. reportbug has a "debian-installer" flag, I assumed it was for this purpose. > I'm the guy who's done the work for the mixed-EFI case here.

It's > the reason why I explicitly only added support for mixed-EFI to our > multi-arch i386/amd64 CDs and DVDs in the first place... Actually, that was the easy part. Except for a custom built grub-efi-i386 and some manual fiddling to find the install disc, I didn't need to do anything. I've been experimenting with a bunch of Intel Bay Trail tablets lately, and they all come with a full-featured (as far as Atom goes) 64bit Atom CPU. However, since the manufacturers usually only fit 1 or 2 GB of RAM into their devices, they ship with a 32bit Windows 8, and consequently, only a 32bit UEFI BIOS. All those UEFI BIOSes I've seen so far will boot any 32 or 64 bit Linux kernel just fine, provided that: - you have a 32bit EFI bootloader (like grub-efi-ia32) - you disable Secure Boot or register the bootloader as trusted - the 32bit bootloader will load a 64bit kernel (which grub-efi-ia32 does) When building grub-efi, you also need to make sure that all necessary modules are compiled in, as grub will refuse to load external modules in Secure Boot mode. I should note though that not everything is running smoothly yet. On one particular device, the installed system only boots occasionally, usually just hanging at the Loading initrd... prompt.

Hi Gregor, I'm the guy who's done the work for the mixed-EFI case here. How did you get the amd64 installer DVD to boot on your 32-bit UEFI system in the first place?

Control: reassign -1 debian-cd
This is actually the responsibility of the debian-cd package,
reassigning.
