Re: Question about xserve G5

I'm trying to boot the XServe with serial console, and I get to the
kernel, but immediate after I start getting garbage on the screen (the
bauds change to 9600).

My issue is that after I reach a point where I have to type something I
have no input whatsoever, and I suspect it might be because of this
sudden change in bauds.

I'm trying to set kernel arguments to fix the bauds to 57600, but I just
can't find the correct one.

Does anybody know how to do it without recompiling the kernel?


Kind Regards,

Javi.
