Ok, I tried to modify mk/devel.mk to put: GCCWARN += -Wno-clobbered -DCORE_DEBUG=1 -DDEBUG_MALLOC -DDEBUG_THREAD And removing the -DDYNAMIC_DEBUG but now syslinux doesn't want to build: ranlib liblpxelinux.a ld -m elf_i386 -Bsymbolic -pie -E --hash-style=gnu -T /root/syslinux/core/i386/syslinux.ld -M -o ldlinux.elf ldlinux.o \ --start-group libcom32.a --whole-archive /root/syslinu...

Not sure for Fedora, but the system is installed with either RHEL6, RHEL7 or Ubuntu 14.04 depending on the Lab I'm making on it without issue. >Just to make sure that the firmware works so far.

I should restate: A serial port that responds on BIOS IO port 3F8h that can reliably operate at 115200 8n1 may

This patch adds support for printing messages through a debug console. QEMU, for example, supports this through the debugcon facility. The benefit is that it's *much* faster than printing over a serial port. To print to I/O port 0x402 (the default used by SeaBIOS and OVMF), add "-DDEBUG_IO_PORT=0x402 -DCORE_DEBUG=1" to the build CFLAGS. To enable a debug console in QEMU that
