Is the "send message to install server" actually needed. I don't know your
setup.
I have made netbootable DOS images to do firmware updates, but without any
networking in the DOS image. I wrote the image to load any needed hardware
drivers, have the firmware updater directly in the image, run the updater
from an autoexec.bat file and then reboot. All automatic Woolah! Updated
nodes.

Subject: [Beowulf] BIOS
Hello,
we are interested in flashing a BIOS image and in manipulating the NVRAM
of the motherboard
automatically.
Unfortunately, using certain vendors, the access to the NVRAM is not
straightforward.
These vendors are offering DOS tools only, to write in the NVRAM, hence,
we have to boot
a DOS image and here starts the trouble.
Optimally, using the DOS environment does following things:
* flashes the BIOS
* sets the NVRAM
* sends a message to the install server
The last point is necessary to prepare pxeboot for the installation
process.
It also means, we need networking under DOS.
In particular, we are looking for a DOS-DHCP client. Everything needs to
be packed on
a 2,9M floppy image.
Has somebody experiences with this?
In the worst case, the DOS environment is working autonomously and the
install server is 'guessing'
whether the BIOS is flashed or not on the clients,
e.g., by analyzing the DHCP logs, but this is not what we really want.
Regards
Henning Fehrmann
