I installed EFI grub (svn r2024) on a Mac Mini (1.8GHz Core 2
Duo) following the instructions at http://grub.enbug.org/TestingOnEFI.
Grub seems to work fine: the menu works, and I can either boot
a Linux kernel or I can "chainload" OS X via /usr/standalone/i386/boot.efi.
I had previously attempted to use elilo (an old binary I
downloaded from somewhere), but it didn't seem to be able to
load the initrd correctly.
There do seem to be two problems -- I don't think either of
them are grub's fault, but I thought I ask just in case
somebody has seen either one before:
1) I blessed grub.efi using this command adapted from the Wiki page:
bash-3.2# bless --mount=/efi --verbose --file=/efi/grub/grub.efi
--setBoot
EFI found at IODeviceTree:/efi
Mount point for /efi is /efi
Mount point is '/efi'
No BootX creation requested
No boot.efi creation requested
GPT detected
Booter partition required at index 2
System partition found
Returning booter information dictionary:
<CFDictionary 0x109320 [0xa08891a0]>{type = mutable, count = 3,
capacity = 3, pairs = (
0 : <CFString 0x18db0 [0xa08891a0]>{contents = "Auxiliary
Partitions"} = <CFArray 0x103a80 [0xa08891a0]>{type = immutable, count = 0,
values = (
)}
2 : <CFString 0x18da0 [0xa08891a0]>{contents = "Data
Partitions"} = <CFArray 0x109770 [0xa08891a0]>{type = immutable, count = 1,
values = (
0 : <CFString 0x109750 [0xa08891a0]>{contents = "disk0s1"}
)}
3 : <CFString 0x18dc0 [0xa08891a0]>{contents = "System
Partitions"} = <CFArray 0x104ff0 [0xa08891a0]>{type = immutable, count = 1,
values = (
0 : <CFString 0x109670 [0xa08891a0]>{contents = "disk0s1"}
)}
)}
Relative path of /efi/grub/grub.efi is \grub\grub.efi
IOMedia disk0s1 has UUID CD08BC7E-4A45-4814-A27A-7FA6D02A2F3A
Setting EFI NVRAM:
efi-boot-device='<array><dict><key>IOMatch</key><dict><key>IOProviderClass</key><string>IOMedia</string><key>IOPropertyMatch</key><dict><key>UUID</key><string>CD08BC7E-4A45-4814-A27A-7FA6D02A2F3A</string></dict></dict><key>BLLastBSDName</key><string>disk0s1</string></dict><dict><key>IOEFIDevicePathType</key><string>MediaFilePath</string><key>Path</key><string>\grub\grub.efi</string></dict></array>'
Setting EFI NVRAM:
IONVRAM-DELETE-PROPERTY='efi-boot-file'
Setting EFI NVRAM:
IONVRAM-DELETE-PROPERTY='efi-boot-mkext'
NVRAM variable "boot-args" not set.
Now the machine boots into grub, but there's about a 30
second delay between the "chime" and when grub starts (it
was the same for elilo). If I have a USB flash drive
plugged in, I see the activity LED flash once every 2
seconds or so until grub starts.
If I hold down the "option" key on startup, there is no
delay and I immediately get the screen where I click on a
button underneath a picture of a hard-drive to boot.
Any ideas on how to eliminate the 30s delay?
2) With the linux kernel command line option video=vesafb, I
get a working console, framebuffer graphics don't work.
Without that option, I don't get a working console. It's
not a grub problem, but any pointers will be appreciated.
