There is no OS. There are no drives.
I'm attempting to boot to cdrom. As of now, I cannot manage to get a working
kernel. Every version and configuration I've tried from 2.6.25 through
yesterday's sparc-linux git repo hangs at some point in the kernel

I have never tried to use the RSC card. I have successfully used the ttya
port, and printenv shows sane settings for both current and default serial
Maybe there's some obp var that I'm missing, I went through the entire manual

Is there a way to change the "default" value of obp vars? Or are they really
I have yet to successfully boot outside of diagnostic mode.
I can power-on to diagnostic mode, (wait for the tests to finish), then:
ok: boot cdrom
at which point it reboots, skips the tests, then boots the cd.
But, if I power up in normal mode, it gets to the ok: but does not accept any
input at that point--I presume the console has been redirected to never-never
land. Why would it redirect the console at that point--right after it prints
the prompt? Makes no sense to me.
