mezzanine board

mezzanine board

[Richard Hartensveld]

Hi,

I've got a challenge S with hardhat 5.1 running on it.
This machine is also equiped with a mezzanine board. (2x diff. scsi and
an ethernet port).

Is there any documentation available for this board or are/where there
ever plans to build a
driver for this board ?


Cheers,

Richard

Sorry for not answering your question in the first place, but:

I didn't know HardHat 5.1 could run on Challenge S. Could you please
send me the specs (hinv) and kernel details (did you compile yourself
or picked it up), so that I can update the www pages?

Thanks,

Sure, just hook-up a terminal to the serial port, link /dev/console to
/dev/ttyS1 on your nfs-root, and don't forget to change
setup-1.9.1-2.noarch.rpm to add some securetty's so that
you can log in over the network as root. (Hardhat doesn't add a normal user at
installation, a missing future, i think).

Well, no hinv since i'm not running irix on the machine anymore (i boot  it
over the network), but here's the dmesg from within linux.This is a
self-compiled kernel, using the cvs tree from linus.linux, but the kernel
included with the hardhat package installs just as good.
If you wish, i can send you the rebuild setup...noarch.rpm to put on the
webpage for other people who wish to try linux on a S.


If someone is seriously interested in do some other development on this
machine, i'm more then willing to give away a shell account for this person.

I've added this to the http://www.linux.sgi.com/manhattan/ page.
A note about Challenge S has also been added to other pages.

To others on the list: shall we make a new page with setups? Otherwise
I'd just link Richard's setup from /manhattan/.
