[ydl-gen] headless configuration

[Richardson, Jeremiah]

I've had the problem with getting yaboot to load.  You have to boot into
open firmware and set the environment variable BOOT DEVICE to the hard
drive partition where yaboot is.  I'm not sure of the exact syntax but
something like "setenv BOOTDEVICE hd:2,\\yaboot"  If you have trouble
getting the exact syntax, I can check for you.  Let me know how this
works for you.

I'll give your procedure a try on the next install.  We ended up finally
getting the other machine to boot off of an imaged drive after playing
with the openfirmware setting.  We turned the network boot off and set
all the output and input to scca.  We still have an issue with the
yaboot automatically booting the image.  So we turned autoboot off, so
you just go through the console server and type boot to bring the
machine up as a temporary fix until we figure out what's happening.   We
have another machine getting installed very soon, so I'll give your
instructions a try.  I think that boot command you listed is definitely
going to come in handy.

Thanks for your help and the information!   

Thanks,
Chris

Here's how I did the installation using Yellow Dog 4.0 on an Xserve.
First, I used a serial connection to a laptop with a null modem adapter
in there.  On the laptop I am running HyperTerminal.  I am using the
following settings

Port: Com1 (may need to use another com port)

Bits per second : 57600

Data Bits: 8

Parity: None

Stop bits: 1

Flow Control: Xon/Xoff

Then, I connect the HyperTerminal and start the Xserve with the first
YDL CD in it.  As I start the Xserve, I am holding down the button with
an exclamation mark inside of a triangle until the top LED's are
blinking in a one after the other sequence, bouncing back and forth.
Then, I release the button and push it six more times.  The bottom LED
should now be on the seventh LED (or the second from the left).  I push
and hold the button until I see output in the HyperTerminal on the
laptop.  This should have booted the Xserve into OpenFirmware mode and
there should be a command prompt in HyperTerminal.  Then, I type this
into the prompt "boot cd:,\\yaboot"  and this should load the Yellow Dog
Installer.  From there, this continues as a normal YDL installation.
Let me know if any of this works for you.  Also, I gained a good bit of
experience with this exact situation while beating my through it, so if
you need any more help don't hesitate to ask.

I have a couple apple Xserves running with a 2 Ghz single G5 processor.
I've installed  YDL on one of them.  I had to install a video card in
the machine to be able to install the OS.  I am unable to set the second
machine up in a headless configuration(using a serial connection for a
console).  On the YDL webpage under platforms supported it lists Xserve
and under that there is a note that implies that to run headless, there
are 2 options Y-HPC or manual configuration.  Does anyone know what the
manual configuration steps are or where they are documented.  I've tried
quite a few different things that have been posted in the forums as well
as all over the web with no luck.  

Thanks!
Chris
