Yesterday I asked about installing FDDI boards in a turbochannel alpha.

My original question was:
Hello managers,
I have a Dec ALpha3000/400. We want to add a turbochannel FDDI SAS
controller and use FDDI instead of ethernet.
I understand that I have to rebuild the kernel, and do a netsetup and
configure the new device.
My question is: Is this all I have to do? Will doconfig recognize the
FDDI card, or should I modify the kernel configuration file.
My second question: I would like to keep the shutdown time to minimum.
I would like to build the kernel before shutting the machine and
installing the board (to save some time). Can I do this? What
options do I need to specify when building the kernel?
Thanks in advance for any help.

If you have booted /genvmunix, it will recognize the kernel.

I don't recommend going this route.
Shut down the machine, put in the card, boot /genvmunix, run doconfig,
mv /vmunix /vmunix.old then cp /sys/FOOBAR/vmunix / and reboot. Then,
use /usr/sbin/netsetup to add the fddi interface, and when it asks you
if you'd like to restart the network, say yes. This is what the manual
says (you know, that sys admin manual) and it avoids having to guess at
things like turbochannel slot numbers, config file syntax, etc. If you
make one wrong guess you've just lost your time advantage.

After installing the hardware, I would boot to the generic kernel
(genvmunix) so that the new hardware would be found on boot. Then rebuild
the kernel with 'doconfig', and you should not have to modify the config.
file.
I do not know of any way to build a new kernel prior to adding the new
hardware.

It was all I have to do...

Hmm.. I think
controller fta0 at * vector ftaintr
is enought. If you boot on a generic kernel (with all device and controllers defined, you shouldn't have to create a new kernel.
From: chu_at_musp0.Jpl.Nasa.Gov (Eugene Chu)
I did the following:
1. Add the line to your config file:
controller fta0 at tc0 slot 1 vector ftaintr
In my case, my card was in slot 1, but you have to set that to your slot.
2. Type doconfig -c config_file to build the new kernel.
3. Move the file /vmunix to /vmunix.sav (or something similar)
4. Move (or copy) the file /sys/MACHINENAME/vmunix to /
5. reboot
If all went OK, your machine should be back up in a couple of minutes,
at which point you can run netsetup. (and delete the old vmunix if you
want to).

Kevin,
Please let me know what you found out.
Thanks.

You have to run the program sizer inorder to recognize the new device
and then rebuild the kernel.

Generally, the recommended DEC procedure is to shutdown, install the
card, and then boot with the generic kernel (which probes for all possible
bits of hardware).
Once booted with the generic kernel, you use doconfig to spit out a new
kernel config file, which will now include the fddi board. If you use
doconfig with your current fddi-unaware kernel, you probably won't get
the correct kernel config file. You then build a new kernel, and reboot.
So much for the recommended dec way of doing it.
Alternatively, you can just add the line
controller fta0 at *
into your kernel config file (somewhere near the other controller lines).
You then rebuild, and reboot. Making a copy of your old one of course...
