From 6503cd9d00a2a3cf3c1c32b26f2097fad7ac9c7f Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Wed, 7 Nov 2007 23:13:43 +0000 Subject: Final set of changes to make Alix1c work. Fix IRQ tables (Thanks to Marc Jones) Fix IRQ SLOT # Comment out ram test in early startup. make the debug print in lx/raminit.c a debug print, not emerg print Set the default console log level to 3, but leave in the possibility of running with more info (leave maximum at 11) Signed-off-by: Ronald G.
