   Hello,

   I have a new laptop which does NOT have an option to turn off UEFI (no switch to CSM or legacy).

   The laptop has a weak CPU, so I want to install slitaz as it is so lightweight.

   I tried many different systems (and versions) but the only bootable system I found was an ubuntu daily build (GRUB 2.02~beta2-6).

   The other systems did work, but X broke when booting. I suspect this might be becauses of a missing driver in the linux kernel (ubuntu daily build works), as booting with 'nomodeset' gives me a terminal (TTY1), and starting X gives me error "No screens found!"

   Is it possible to install slitaz on this setup in any way?
   Perhaps through a persistent live USB with a compiled linux kernel?

   you should disable secure boot, otherwise only secure boot enabled distribution will be booted

   I already have that off - I am currently running lubuntu on it.

   The thing is I need to boot slitaz in UEFI mode, which it at the moment does not support (it would take up extra space, too).

   Key Master

   It is my understanding that UEFI requires a 64 bit kernel.
   Problem 1:
   Slitaz 64 kernel will not boot (kernel panics)
   Problem 2:
   Slitaz 64 is not configured for UEFI:
   Kernel configuration required for UEFI :
   http://lxr.free-electrons.com/source/Documentation/x86/x86_64/uefi.txt
   Slitaz 64 kernel config :

   Ah, I see.

   So I assume this is being worked on (with low priority)? Something that might come far in the future?

   its true that not all implementation of grub accept to boot 32bit kernel

   actually i am booting slitaz cooking from a uefi-enabled netbook, with a grub version from sabayon linux and all works fine

   just install grub-efi to hard disk and add slitaz entry (ubuntu grub also works on my system)

   eg. in my nbook:

   menuentry "slitaz 5 - 3.2.53-slitaz" {
   set gfxpayload=keep
   insmod gzio
   insmod part_gpt
   insmod ext2
   set root='hd0,gpt6'
   search --no-floppy --fs-uuid --set d3f5e161-09fd-4b4d-8874-e33a8d82c798
   echo 'Loading Linux slitaz ...'
   linux /slitaz/boot/vmlinuz-3.2.53-slitaz kmap=it sound=noconf --
   initrd /slitaz/boot/rootfs.gz
   }

   Ah, I see.

   But how'd you install slitaz itself? Just a manual "by hand" install?

    I have explained a way to install it on the EFI System Partition (ESP) installed by Ubuntu. Refer it to create new partition and install or on ESP from another distro.

    @marcb Ciao, posseggo un tablet con bios UEFI, sono riuscito ad installarci sopra Debian normalmente.
    Per avviarlo ho dovuto sostituire il bootloader originale con uno modificato.

    Mi spiegheresti brevemente come installare Slitaz con questo bios? Dato che Slitaz non supporta UEFI non so bene come comportarmi

    Grazie mille in anticipo

    hello, mich-C

    first, please use english when posting on an english thread located in the english forums.

    secondly, there is not yet any end-user way to install slitaz on efi systems :
    you can try to do the same as the guy who did it explaining on his blog, like modifying grub uefi configuration installed by ANOTHER DISTRO, which is very weird from slitaz distr.

    or you can wait, post on slit'forum or ask to pascal bellard and others devs from slitaz team to build a slitaz ISO including an EFI System Partition which slitaz doesnt have YET.

    (yes, we are waiting for it, or for a way to do that without any other distr)
