    Description

    I’m having fun delving into UEFI systems now and I have a `problem’, or rather a question.

    Has anyone got any EFI exit type other than rEFInd to work universally?

    ‘EXIT’ as an option always elicits a chainloading error for me, while the other options are hit and miss.

    @george1421 That sounds good.

    @Tom-Elliott I might say not to change the default for existing installs, but for new installs I would think that refind is more appropriate of a choice. I wasn’t aware that you adjusted/fixed the default settings in the conf file (nice job!).

    I think today moving forward that refind would be a good choice. I also agree with your justification about changing the default for already installed FOG environments.

    I’ve already adjusted the refind.conf file to use the “internal” setting that most others were having to change there file for.

    The reason “EXIT” was used as the default was at the time this modification was added EXIT was really the only option. Grub types wouldn’t work with EFI, and SANBOOT either. We didn’t have reEFInd back then.

    I’m not changing the “default” option. Why? Because that was added quite a LONG time ago. To ‘fix’ it would mean it would only be good for new installs. If I define the exit type for this implicitly, it means those who update will have their configurations changed as well, only really noticeable if they aren’t using rEFInd.

    it’s a GUI Update to set either individually on hosts or as the default. I’d more lean on saying put it in the “gotcha’s” under the EFI information on the wiki.

    The bottom line, “Could I change it?” Sure I could. “Should I change it?” I don’t think so. Especially now.

    @george1421 I’ve never had to tweak it, but I know a few people here have.

    @Wayne-Workman said in EFI Exit types:

    @Developers The default FOG_EFI_BOOT_EXIT_TYPE probably should be REFIND_EFI or GRUB. I’ve had the most luck with REFIND_EFI in my own experience.

    (Thinking big picture here) Then we probably need to focus on the default settings for rEFInd too. If people have to tweak the config file we should find out what they are changing and how it solved their problem.

    I see what your getting at.

    You can change your default on your own, right here:
    Web Interface -> FOG Configuration -> FOG Settings -> FOG Boot Settings -> FOG_BOOT_EXIT_TYPE & FOG_EFI_BOOT_EXIT_TYPE

    For the record, I vaguely remember one guy here that had to use the EXIT one because none other would work on the system model he had.

    @Developers The default FOG_EFI_BOOT_EXIT_TYPE probably should be REFIND_EFI or GRUB. I’ve had the most luck with REFIND_EFI in my own experience.



  • Okay, let me put it another way.

    Does the default FOG setting for `Exit to Hard Drive Type(EFI)’ of EXIT work for anyone?

    Not universally.

    At my old job, some were set to rEFInd, some to grub.

    there isn’t an option that works for everything, this is why the setting is adjustable per-host.
