Re: [PATCH] bless command

[Vladimir Serbinenko]

Hello, thank you for the testing. Two concepts together (system folder and system file) are clearly redundant. I thought that intel macs look which folder is blessed and load boot.efi file from this directory. Here I attach a patch which updates finderinfo[0] when argument is a directory and finderinfo[1] when argument is a file. Can you do a test and tell me which concept is really used by intel macs? When doing tests don't forget to hold option key and select your testing partition. I will do a similar test on my ppc mac

Hi,

Tested and works on Apple imac81 with Mac OSX 10.5, patch applied to r 2074

grub> hfspbless (hd0,3)/efi

Last login: Sun Apr 19 14:30:23 on console

im81:~ pxw$ bless --info /Volumes/hfsp 

finderinfo[0]:     52 => Blessed System Folder is /Volumes/hfsp/efi

finderinfo[1]:      0 => No Blessed System File

finderinfo[2]:      0 => Open-folder linked list empty

finderinfo[3]:      0 => No OS 9 + X blessed 9 folder

finderinfo[4]:      0 => Unused field unset

finderinfo[5]:      0 => No OS 9 + X blessed X folder

64-bit VSDB volume id:  0x0F87F7680B9C5211

im81:~ pxw$ 

Now it just needs to bless the file in order to boot from grub.efi on Apple EFI

hfspbless <DIRECTORY> <FILE>

This would be VERY useful, making grub.efi boot possible on Apple Mac without needing Mac OSX or refit.

hfspbless is fine for a name

Hello, due to request by ams I wrote this. It's an analog of "bless" command available under OSX rewritten using grub2 fs functions and according to apple specification of hfs+ on-disk format. This command only update the blessed folder on a partition it doesn't change which drive is used for booting. The later will be a separate command. Also you can choose which volume to boot from by holding option key. Syntax:
hfspbless <DIRECTORY>
It works only on HFS+ volumes. Also due to the lack of hardware I wasn't unable to test this "in vivo"
