Booting linux from sgi indy.

Hi!

How can i cause an indy to boot linux automatically, the bootloader seems to drop that root=/dev/... parameter.
Is there a way to boot without having an irix running? The most unusual way would be to build a 20mb efs partition for some kernels and mount it at another sgi, to copy over new kernels, but that won't be the solutions i'm looking for.
Is there a way to use the sound processor and/or the indycam?

It would be very kind if someone helps me.

I have managed to get my Indigo2s to boot by themselves (actually with the help of a bootp/tftp server). I modified init/main.c like so:

static struct kernel_param raw_params[] __initdata = {
+ { "OSLoadOptions=", root_dev_setup },

        { "root=", root_dev_setup },

Then, at the boot prom prompt, I typed:

setenv -p OSLoadOptions /dev/sda1

This string is passed by bootp into the loaded kernel and everything boots up without any user intervention.

Personally, I would like to have a better way to do this, but this works for me, and I haven't found any drawbacks except needing to add on line to kernel code.
