BIOS

[Henning Fehrmann]

Hello everybody,

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 flashes the BIOS, sets the 
NVRAM and sends a message to the FAI server to prepare the next boot of the clients for the
installation.
This means, we need networking under DOS. In particular, we are looking for a DHCP client.

Has somebody experiences with this?

In the worst case, the DOS environment is working autonomously and the FAI server is 'guessing'
whether the BIOS is flashed or not, e.g., by analyzing the DHCP logs, but this is not what we really want.
