Hi!
I'm trying to get tboot to work, but I'm getting nowhere fast.
I've installed tboot (1.7.4-0ubuntu1 via apt-get) on xubuntu 32-bit (kernel
3.11.0-18-generic) on my machine (Lenovo Thinkpad Helix 3701).
Then I put the 3rd_gen_i5_i7_SINIT_67.BIN file in /boot/ directory (got it
form intel web page).
I edited relevant lines in /boot/grub/grub.cfg to look like this:
submenu "tboot 1.7.4" {
> menuentry 'Ubuntu GNU/Linux, with tboot 1.7.4 and Linux 3.11.0-18-generic'
> --class ubuntu --class gnu-linux --class gnu --class os --class tboot {
> insmod part_msdos
> insmod ext2
> set root='hd1,msdos1'
> if [ x$feature_platform_search_hint = xy ]; then
> search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1
> --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1
> 1ffcf898-aa43-4729-873a-f17bd4342ca0
> else
> search --no-floppy --fs-uuid --set=root
> 1ffcf898-aa43-4729-873a-f17bd4342ca0
> fi
> echo 'Loading tboot 1.7.4 ...'
> multiboot /tboot.gz /tboot.gz logging=serial,vga,memory
> vga_delay=5
> echo 'Loading Linux 3.11.0-18-generic ...'

> echo 'Loading ACM module ...'
> module /3rd_gen_i5_i7_SINIT_67.BIN
> }

After this i reboot and select "tboot ..." in grub menu.
After displaying "Executing GETSEC[SENTER]..." the machine reboots and on
the next attempt I get the following error:
TXT.ERRORCODE: 0xC00010c1
> AC module error: acm_type=0x1, progress=0x0c, error=0x4
>
I've decoded the error code as per SINIT_Errors.pdf from the intel web page:
1 - Valid
> 1 - External software
> 000000 - Reserved
> 00000000 - Minor Error code
> 0 - Sotware source
> 00100 - Major error code
> 001100 - Class code
> 0001 - Module type
>
Acording to the pdf this indcates: Class ACPI Check, DMAR not found.
I have really no idea where to go from here, what do you guys suggest?
I would have included more logs in this message, but I only have them in
JPEGs since I had to take pictures of the screen to save the output. If you
think it will help I will attempt to transcribe them to text and post a
link to pastebin ?
Thank you in advance!
