[9fans] making plan9 use sdD0

[ron minnich]

the boards I have come up with IDE on sdD0, not sdC0.

Any good ideas on how to make Plan 9 look there?

thanks

oh, no, not that easy.

I don't want booting on sdD0 to be an option. I just want plan9 to always
boot il, but to use sdD0/nvram for the nvram.

Does that make any more sense?

Set the nvram environment variable somehow; that'll do it.  You guys
are using a custom version of 9load, if I recall correctly.  Do you
have some mechanism for setting the environment?

ah, ok. I'll let andrey tell me how :-)

that sounds good to me.

Now I realize I never looked to see how env got from 9load to plan9, so
that's next.

set nvram=#S/sdD0/nvram
in your plan9.ini

OK, I would do this but just noticed that 9load is not finding sdD0.

OK, why would this happen? (Yes, I'm perusing code but still haven't seen
why).

thanks

It shouldn't matter that 9load doesn't see sdD0 (unless you have a
plan9.ini on it), since nothing touches nvram in 9load.

So I think I want 9load to see sdD0 to get plan9.ini so I can set env
variables.

9load has an old version of the ata driver,
and it probably can't handle the lack of sdC0.
i'm surprised the kernel proper handles it.
it's very weird that your first ide interface
doesn't configure itself as sdC0.

it's the way this board works. Compact flash is sdD0.

Not fixable.

Sorry, I'm confused; I thought you guys had a custom 9load that ignored
disks and things like that, and just booted from the network.  I assumed
you had a mechanism for hardwiring environment variables that would be
sufficient.  My bad.
