1Plan 9 from Bell Labs kernel images require additional setup to pass 2configuration information to the kernel. An environment variable named 3confaddr must be defined with the same value as CONFADDR (see mem.h). 4Use of this facility is optional, but should be preferable to manual 5configuration. 6 7When booting an image, arguments supplied to the bootm command will be 8copied to CONFADDR. If no arguments are specified, the contents of the 9bootargs environment variable will be copied. 10 11If no command line arguments or bootargs are defined, CONFADDR is left 12uninitialized to permit manual configuration. For example, PC-style 13configuration could be simulated by issuing a fatload in bootcmd: 14 15 # setenv bootcmd fatload mmc 0 $confaddr plan9.ini; ...; bootm 16 17Steven Stallion 18June 2013 19
