From 47dcd392dcd79d02eec2714696012785dd7a47c9 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Tue, 12 Jan 2016 15:35:06 +0000 Subject: [debug] Allow debug colourisation to be disabled Some BIOS console redirection capabilities do not work well with the colourised debug messages used by iPXE. We already allow the range of colours to be controlled via the DBGCOL=... build parameter. Extend this syntax to allow DBGCOL=0 to be used to mean "disable colours".
