    Exclamation Re: grub2 EFI boot loader internal/external booting

    I'd finally installed grub-efi on my macbook 2.1 an d now i have snow leopard and ubuntu lucid. The only problem now is that i can not use bright keys under kde, it fails to adjust the screen brightness. (but using grub-pc works)

    Here's my grub.cfg:

    Code:
    set timeout=100
    
    
    menuentry "MacOSX Snow Leopard" {
      chainloader /usr/standalone/i386/boot.efi   
    }
     
    menuentry "Linux" {
      loadbios (hd0,5)/boot/vbios.bin (hd0,5)/boot/int10.bin
      linux (hd0,5)/boot/vmlinuz-2.6.32-22-generic root=/dev/sda5 ro  video=efifb    quiet splash
      initrd (hd0,5)/boot/initrd.img-2.6.32-22-generic
    }
    I there any problem using the load bios option along the kms kernel module? i cannot adjust my lcd brightness !

    Have you tried pommed? It got the brightness keys working for me, but that was in Gnome, so I don't know if it's available for KDE.

    I have no idea about editing your bios or kernel or anything.

    Hopefully someone more knowledgeable in the code arts will come along with better suggestions.

    Re: grub2 EFI boot loader internal/external booting

    hej folks,

    I got a little problem using a Ubuntu 10.04 Lucid Lynx Installation, put to an external hard drive, and my MacBook. Like in many threads mentioned I already installed rEFIt successfully...The problem: My bootloader, that means rEFIt recognizes the Linux-Partition on the plugged-in external HD, and when I select it, the penguine appears for some seconds. Then "the dash" appears in the upper left corners, it appears to blink some times, and exactly in the moment where I get happy that it seems to work, Windows (found on my internal HD, installed vie BootCamp side by side with Snow Leopard...) is starting to boot! I tried many things, I reinstalled GRUB several times, same try with the MBR of the external HDR and more on....Now I found myself reading through the german Ubuntu-Wiki and I discovered this project, used mainly when setting up a Live-USB media. I wondered if it could be needed/useful to install the grub2 EFI boot loader on my external HD and if yes, how I can manage this. Or do you guys got any other ideas solving my problems? I would be really, really, really happy to finally start using Ubuntu, I even can´t wait for it, so please help me folks

    Re: grub2 EFI boot loader internal/external booting

    I compiled an image (tried with both 1686 and x86_64 target) of grub 1.98 and it work with rEFIt! But when I try to bless it with

    bless --folder=/ --file=/efi/grub/grub.efi --setBoot

    MacOSX start without showing a menu. What am I doing wrong?

    Re: grub2 EFI boot loader internal/external booting

    Hi!

    I'm facing the same problem (Macbook Pro 7,1, Geforce 320M). I have tried loading a prerecorded video BIOS image, but it didn't help. Have you found any solution?

    Re: grub2 EFI boot loader internal/external booting

    Has anyone had any success with Lucid on the macbook pro 5,5?

    I set up my hard drive like this:
    /dev/sda1 HFS+ 1GB
    /dev/sda2 ext4 127GB

    and put grub2 (which I compiled from source) on the first partition and blessed it with OS X. Grub2 starts fine, and it loads the kernel and initrd, but it freezes when I enter the boot command.

    Code:
    root=hd0,1
    linux /vmlinuz-2.6.32-24-generic root=/dev/sda2 rootfstype=ext4 video=efifb
    initrd /initrd.img-2.6.32-24-generic
    boot
    _
    I've tried it with fix_video, fakebios and loadbios using a vbios and int10 bios captures... nothing seems to work. Maybe it's an issue with this kernel: Fedora 13 boots fine using a 2.6.33 kernel... so tonight I'll try Karmic and Maverick and see if something else will work.

    Any ideas?

    Thanks,

    Taoye,

    It looks like I have a similar problem.
    I have rEFIt 0.14, Ubuntu 10.04 32-bit and grub-1.98 downloaded and compiled from gnu.org, and I added in my kernel parameters :
    Code:
    video=efifb:base:0xc0030000,stride:2048,width:1440,height:900
    Grub seems to hang at the end :
    Code:
    ROM image is present
       [Linux-bzImage, setup=0x3400, size=0x3d56c0]
    Video mode: 1440x900-32@0
    Display Controller: 2:0.0
    Device id: 64710de
    MMIO(0): 0xe4000000
    VMEM(1): 0xc0000000
    MMIO(3): 0xe2000000
    Frame buffer base : 0xc0030000
    Video line length: 8192
       [Initrd, addr=0x3f7fff000, size=0x7f0349]
    Any idea ?

    Hey, I just wanted to tell everyone here that using the patch from this thread (http://140.211.166.79/mailarchive/li...4607435/thread) I am able to boot without the noefi option on a mbp 6,2. dmidecode, applesmc etc. work great.
