UPBADOOM

Uncomplicated Pre-Boot Authentication and DOOM image

Just another SED PBA with the option to play fbDOOM.

Important

SYSLINUX has trouble booting the bzImage (kernel) built by buildroot.
The immediate fix is to replace it with a working one from e.g. ChubbyAnt's repo.*
Not sure what causes this problem, might want to use a Unified Kernel Image in the future instead.

* If you're not sure how to do that, this guide might provide the basic steps to repacking the image: Drive-Trust-Alliance/sedutil#259

The project is made using buildroot and a few basic components:

• The base Linux system
• fbDOOM
  • shareware WAD
• sedutil-sha512 (ChubbyAnt's fork)*
• Syslinux
• UPBADOOM: the actual Pre-Boot Authentication program

* To enable the original sedutil replace BR2_PACKAGE_SEDUTIL_SHA512=y with BR2_PACKAGE_SEDUTIL=y in buildroot-external/board/upbadoom/x86_64/configs/x86_64_defconfig
