[Trustedgrub-users] Newbie question

[<de...@de...>]

Hello,

I realize this is probably a stupid question, but since Trusted =20
GRUB's documentation is lacking (as far as I could spot, it's just a =20
quick HOWTO in the README file and something similar in the shell =20
script for compiling the software), I don't even know where to start =20
troubleshooting.

I'll state upfront that I'm not familiar with GRUB, only lilo. Also, =20
I'm using Gentoo Linux. I emerged (installed) plain GRUB and modified =20=

the sample config file and I had a working bootloader. Then I =20
unmerged (uninstalled) plain GRUB and installed Trusted GRUB =20
following the instructions (copying the newly compiled stage1 and =20
stage2, plus the `default' file, to /boot/grub). I cleaned up the old =20=

stage1_5 loaders left over from the plain GRUB installation. Having =20
kept my working config file from plain GRUB, I ran the newly =20
installed grub-install and everything seemed to go smoothly. However, =20=

when trying to boot the computer, I can only see a brief flash of =20
`tGRUB' on the screen before the computer reboots itself. I tried =20
recompiling with the -DDEBUG flag but no debugging info was printed =20
-- probably it's failing at an early point in the boot process, =20
perhaps still at stage 1.

My hardware is an Intel D915GMH mainboard with Infineon 1.1b TPM =20
chip. I'm using kernel 2.6.17 and the Infineon TPM drivers in the =20
kernel. The TPM itself is fine -- I succesfully configured it in =20
Windows and did a little bit of fiddling with TrouSerS, tpm-tools and =20=

the apps bundled with IBM's libtpm.

Any help would be appreciated.
