Hello,

We can successfully execute tboot with grub2 built as a legacy
bootloader and selecting the legacy boot option in our Insyde BIOS.
However, if we build grub2 for EFI and select EFI boot in the BIOS, we
get a system reset after GETSEC[SENTER].

The output from parse_err:

AC module error : acm_type=0x1, progress=0x0a, error=0x2

which translates to: "RSDP ACPI table checksum invalid"

in the sinit_errors.txt from i5_i7_DUAL-SINIT.tar.gz.

We're running the latest tboot from bughost.org.

Does tboot support EFI booting? It's curious that everything works
with a legacy boot, but not with EFI. Is this an indication of a
possible BIOS bug?

Thanks,

-Mike
