Author: rminnich Date: 2007-11-08 00:13:43 +0100 (Thu, 08 Nov 2007) New Revision: 2952
Modified: trunk/LinuxBIOSv2/src/mainboard/pcengines/alix1c/Options.lb trunk/LinuxBIOSv2/src/mainboard/pcengines/alix1c/cache_as_ram_auto.c trunk/LinuxBIOSv2/src/mainboard/pcengines/alix1c/irq_tables.c trunk/LinuxBIOSv2/src/northbridge/amd/lx/raminit.c trunk/LinuxBIOSv2/targets/pcengines/alix1c/Config.lb Log: 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)
