Unfortunately, you do not provide any logs, making it hard to see where
it fails. So, please reply with the following information.

1. Your coreboot configuration (`.config`).
   2. The output of `build/cbfstool build/coreboot.rom print`.
   3. Build the utility cbmem with `make -C util/cbmem`.
   4. The output of `./util/cbmem/cbmem -c`.
   5. The output of `./util/cbmem/cbmem -t`.

Thanks,

Paul

Afaik list-servers can be configured to filter HTML. Doesn't the cb-
Server implement this on purpose?

ok, done.

both commands fail with "Failed to gain memory access: Permission denied"

But I think before I'll try to improbe booting time, I need to make sure that:
- the 2nd part of the BIOS (the 8MB chip) is flashed
- additional payloads are working
- write proper documentation about everything to save others asking the same (maybe annoying) questions...
