Some BIOSes may not have a an option to enable VT-d and may either always
enable it or tie it to VT.
After enabling VT and the TPM (which should then allow you to enable TXT), give
tboot another try and see if you still get an error. And if you get a reset
after “executing GETSEC[SENTER]…” then let it reboot and execute tboot again,
saving the serial output from both boots (tboot will print the TXT.ERRORCODE
when it runs).

Yes, VT-d is required to run tboot.
Please check other menus like PCI device, North Bridge, etc to see whether you
can find VT-d option.
Thanks.

Thank you very much for the quick response.
i enabled the following feature in BIOS
a) Embedded Security Device Support
b) Virtualization Technology (VT- X)
but there is no option for Virtualization Technology Directed I/O (VT- D)
so my doubt is Virtualization Technology Directed I/O (VT- D) is it required to
install tboot ?

Please check your BIOS.
It seems your BIOS has disabled TXT. If so, enable it.
Thanks.

Hello all,
I am trying installing tboot, but I have several problems. My PC is HP Compaq
6000 Pro microtower ("Intel Core-2-due E8400 processor" and "Intel Q43
chipset") with Fedora 13.
I have downloaded SINIT(Q45_Q43_SINIT_19.BIN) and tboot-20101005.tar.gz.
I compiled the "tboot-20101005" sorce code and following is my grub.conf I
have modified.
title Fedora (2.6.36 )
root (hd0,0)
kernel /tboot.gz logging=serial,vga,memory
module /vmlinuz-2.6.36 ro root=LABEL=/ rhgb quiet intel_iommu=on
console=ttyS0,115200
module /initrd-2.6.36.img
module /Q45_Q43_SINIT_19.BIN
But I am getting following error message whenever booting this kernel,
