Hi, (It seems that only the tile is shown in my last post.) Currently I'm trying to work on TBOOT. However I get an error which is "TXT.ERRORCODE: 0xc00020a1". I checked the sinit_errors.txt and found this error was due to "device scope of VT-d DMAR ACPI table is invalid". I searched on line and someone said this was due to VT-d unenabled. However I have enabled VT-d in the BIOS. Can anyone give me some help? Thanks, Hu Hong Here is the environment to run tboot: Laptop: Thinkpad T400 BIOS: Version 7UET94WW (the latest version, released on 16 Dec 2012 by Lenovo); TXT, VT, VT-d are enabled. TBOOT: Version 1.7.3 (Released on 2012-12-28); ACM: GM45_GS45_PM45_SINIT_51.BIN OS: Ubuntu 12.04 with 3.5.0-30-generic kernel My grub.cfg for tboot is : menuentry 'Ubuntu, with Linux 3.5.0-30-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail gfxmode $linux_gfx_mode insmod gzio insmod part_msdos insmod ext2 set root='(hd0,msdos1)' search --no-floppy --fs-uuid --set=root 9047b871-f55c-44d1-952c-48bf0de35fcd *multiboot /tboot.gz /tboot.gz logging=vga,memory,serial* module /boot/vmlinuz-3.5.0-30-generic *intel_iommu=on* root=UUID=9047b871-f55c-44d1-952c-48bf0de35fcd ro quiet splash $vt_handoff module /boot/initrd.img-3.5.0-30-generic *module /boot/GM45_GS45_PM45_SINIT_51.BIN* } |
