Hi, Well, the first line, "efi: EFI v2.31 by American Megatrends", is (almost for sure) from /arch/x86/platform/efi/efi.c (assuming this is intel machine; you only replied that it is 64 bit machine, I assume that it is intel). I am not sure that this indeed says that the EFI is active. does efi_enabled() says that efi is active ? not sure. see below. In 3.8.0 kernel, we have: And in arch/x86/kernel/setup.c, we have: ... if (efi_enabled(EFI_BOOT)) efi_init(); .. And: #define EFI_BOOT 0 /* Were we booted from EFI? */ in include/linux/efi.h The question marks are in the header file, not from me. regards, Rami Rosen http://ramirose.wix.com/ramirosen On Fri, Feb 22, 2013 at 4:19 PM, Steven Stern <subscribed-lists@xxxxxxxxxxxxx> wrote: > On 02/22/2013 07:53 AM, Rami Rosen wrote: >> Steven, >> I believe that when EFI is enabled, >> dmesg | grep EFI should yield results. >> >> Is it Intel x86 (32 or 64 bit) based machine ? >> >> Because I see in the efi code this: >> ... >> pr_info("EFI v%u.%.02u by %s\n", >> ... >> >> http://lxr.free-electrons.com/source/arch/x86/platform/efi/efi.c#L676 >> >> I believe it is so also for other platforms, but I did not verify it. >> >> regards, >> Rami Rosen >> http://ramirose.wix.com/ramirosen >> > > This is a 64 bit machine > > $ dmesg |grep EFI > [ 0.000000] efi: EFI v2.31 by American Megatrends > [ 0.597599] fb0: EFI VGA frame buffer device > [ 0.648255] EFI Variables Facility v0.08 2004-May-17 > [ 2.301943] fb: conflicting fb hw usage inteldrmfb vs EFI VGA - > removing generic driver > > > > -- > -- Steve > -- > users mailing list > users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines > Have a question?
