Hi, the display of LSS16 files from a DISPLAY file (as documented in http://www.syslinux.org/wiki/index.php/SYSLINUX#Display_graphic_from_filename:) seems heavily broken since syslinux has been converted from assembler to C. I already discovered one bug in core/include/graphics.h (and core/graphics.c): the pointer VGAFilePtr is of type uint16_t*, but should be plain char*. This bug causes the

We recently have upgraded syslinux and have noticed that the boot logo code via boot.txt no longer works. I have a couple patches that get it close to working but I appear to be having trouble with color maps. Is there someone would want to help me finish figuring this out? Any interest in the patches I have to fix the rle decoder?

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
