I'm not quite sure what you mean by "conventional console", but tested
SYSLINUX 3.35 on a Dell 2650 with a VGA monitor attached. PXELINUX
was set up with CONSOLE 0. I didn't have a serial terminal connected,
but the VGA monitor showed nothing ot the boot loader output but the
splash screen. I have no idea of the mechanism, but looks like it can
cause problems if the BIOS (being stubbornly over-eager) redirects
that to the serial line. Of course I'd prefer the BIOS step back
after starting the boot loader, but isn't it exactly the kind of
problem CONSOLE 0 tries to avoid? If so, I'd consider this a bug.
