It is recommended that you use grml-live to build your own disc.

Loop mount the ISO image:

├── iso      	<-- mount the original iso here

Read the fan speed mode:

ipmitool -H <IP> -U <USER> -P <PASSWD> raw 0x30 0x45 0x00

The values are:

Standard: 0
Full: 1
Optimal: 2
Heavy IO: 4

Hi,

I packaged a few of Intel's out of tree NIC drivers from http://sourceforge.net/projects/e1000/ as dkms based .debs and included them in a custom grml image.

I'll explain how; if there is interest, I can also share my packages (although, as you'll see, they're likely sub-par, because I did not take the time to really understand what I was doing; in particular, I fear the e1000e module may not always build correctly at grml-live time, while it builds
