...essed up - no kernel, no initrd, ... - User selection is really needed (decision with no defined default) So I started with the lss16 graphics, which is nice but limited to 14 clolors I continued with vesamenu background - nice - but I still see messages. I commented out few calls to writestr and writechr in the sources - no more messages or menu. The problem I have now is that before loading the kernel the graphic menu returns to text mode (blank dark screen). How can I tell the vesamenu sub-system not to return to the text mode? Any help will be appreciated, If anyone want the changes I made,...

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific
