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,


TBOOT:mod_num:0
TBOOT:PCR:None

TBOOT:num hashesh:0

Can someone help me solve this problem?
Do you have any suggestions?

Thanks very much.
