Hello, I have a MacBook with a EFI 64-bit. I would like to boot Ubuntu 10.04 32-bit from grub EFI 64-bit. Is that possible ?
The boot freezes after the following output ROM image is present [Linux-bzImage, setup=0x3400, size=0x3d56c0] Video mode: 1440x900...@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] That might be a problem of the kernel, or a video problem (my investigation are related here : http://ubuntuforums.org/showthread.php?t=1557326) I added some "printf" in the "grub_linux_boot" function of the "efi/linux.c" file but they are never reached. Also, I tried to configure grub EFI 64-bit to chainload grub EFI 32-bit, but I get the following error : /EndEntire filepath:/ACPI[…]/File(\efi\grub32)/File(grub.efi)/EndEntire error: cannot load image. Press any key to continue I tried to chainload grub EFI 64-bit to grub EFI 64-bit (itself), and that works fine. Are there any restrictions in loading 32-bit from 64-bit versions ? I looked in the FAQ and in the source code of "efi/linux.c" but I do not see an answer. Thanks in advance, metatech
