trouble about trusted grub, help me please!!!
hi, I am trying to make trusted grub work (refer to http://trousers.sourceforge.net/grub.html) in my linux system with kernel 2.6.27.10 and TPM chip 1.2, but i failed. What i had done is the following: (1) got the grub-0.27.patch from http://trousers.sourceforge.net/grub.html (2) patch grub-0.27.patch into my grub-0.27.src.rpm source package (3) running "rpmbuild -bb grub.spec" (4) running "rpm -Uvh grub-0.27.i386.tcg.rpm" and running "setup" command in the GRUB shell (5) add the measure boot parameter such as "measure (hd0,6)/etc/fs" (6) lastly, reboot the system but the following error arised: "measure (hd0,6)/etc/fs" : Invalid argument. Could you tell me how to resolve the problem? xueyu.hong yuemaill...@gmail.com ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
EFI through virtualization?
You guys wouldn't happen to know any good ways to test out EFI through virtualization. I see some Qemu stuff that is rather old. But I'm not too trusting of it's funcationality now. I'd like to play around and test/debug some of the grub2 efi support, without having to buy a Mac. Any ideas? ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

Hi, This is quite strange, it might be caused by the compiler. You can try my version of grub.efi: http://grub4dos.sourceforge.net/grub.zip -- Bean ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
Re: EFI Boot on MacPro
It is here - (return checked in refit efi shell and gui)
Can't go any further until that is fixed.

This hangs -
codestart:
movq%rcx, EXT_C(grub_efi_image_handle)
movq%rdx, EXT_C(grub_efi_system_table)
+ret
callEXT_C(grub_main)
ret
-
This returns -
codestart:
+ret
movq%rcx, EXT_C(grub_efi_image_handle)
movq%rdx, EXT_C(grub_efi_system_table)
callEXT_C(grub_main)
ret

Would really like to see the solution for the imac8,1.

[PATCH] Fix ATA compatibility mode check
For the compatibility mode check, the ATA driver uses the bits in the
"Revision" byte instead of the "Programming Interface Byte" of the class
value (See T13/1510D). The compat_use[] flags are never set.
This patch fixes both issues.
