Re: [tboot-devel] does tboot-20100910 work for Ubuntu 10.04 with kernel 2.6.35-19-generic?

Hi

> I don't know if 10.04 has TXT/tboot support compiled in or not.

  I saw the tboot need kernel>=2.6.33, but original 10.04 didn't fit,
so I changed the kernel to  2.6.35-19. However, it still didn't work.
  I'm wondering if tboot not only depends on the kernel but also
depends on the upper configuration of Ubuntu?
  Meanwhile, I download the  2.6.35-19, and compiled it with default
configuration, is it possible that I must change some config on this
kernel? and where?

The config in menu.lst is like this (my computer is left in lab, I can
paste the entire menu.lst on Monday, however I still remember the
configuration the tboot entry ):

title tboot
kernel /boot/tboot.gz logging=serial,vga,memory
module /boot/vmlinuz-2.6.35.19 ro root=UUID=.............#(can't remember)
module /boot/initrd-2.6.35.19.img
module /boot/sinit.bin

I've already tested the menu.lst in grub, as in the previous mail:

>> 1. remove the sinit module in menu.lst

It seems the root= or initd works both fine, or it will not success in
booting kernel if "module /boot/sinit.bin" is removed.


Thank you for your letter!
