Enable log messages in all consoles

[shahargli]

hello,

I'm trying to get ipxe log and debug messages in AWS, AWS provides system log which is supposed to provide the same output as physical screen.
I do see printf messages in AWS console, but I cannot see any log messages.
Since I dont know how does ipxe consoles map into AWS console, I'm trying to enable
logs on all consoles, but here is the issue:

What is the correct way to enable log messages in all consoles?
I tried setting:
#define CONSOLE_PCBIOS CONSOLE_USAGE_LOG/* Default BIOS console */
#define CONSOLE_DIRECT_VGA CONSOLE_USAGE_LOG
#define CONSOLE_VESAFB CONSOLE_USAGE_LOG /* VESA framebuffer console */
#define LOG_LEVEL LOG_ALL
at config/local/console.h
but when running:
make DEBUG=iscsi:8,dhcp:8

make fails due to: error: "CONSOLE_PCBIOS" redefined

any help will be appreciated
thanks
