To boot IRIX from an alternate partition, we usually
sash is fetched from
These can be set in the NVRAM using
setenv -p SymbolName SymbolValue
IRIX looks at the environment when booting. That is, it finds
argc, argv, and envp in $a0, $a1, and $a2. It copies them to
private storage before starting up, since they are in memory
which will be overlaid by dynamic memory allocation. All of the
NVRAM and temporary environment variables are passed via envp.
IRIX looks for root= on the command line (in argv) first, and then
in the environment, before falling back on a default. linux could
do the same.
