The data from the BIOS update official requires DOS to work. Iam now going to try it with install freedos, and running it then.
Firstly to do this I needed to install syslinux from the debian repo. With this ramdisk I will be able to boot with freedos later.
After installing it, I copy some files to /boot/, where grub everything excepts:
cp -a /usr/lib/syslinux/memdisk /boot/.
Now we download and extract freedos:
devbox:~# wget http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz
--15:43:34-- http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz
=> `FDOEM.144.gz'

devbox:~# zcat FDOEM.144.gz > /boot/biosupd.fdd
and after that edit the menu.lst to include it.
Here we add this piece:
title BIOS update And now we are going to test this thing first
kernel /boot/memdisk
initrd /boot/biosupd.fdd
The first time after rebooting I made a small mistake, what caused a grub error, but after fixing that it works 
After doing this I mount the biodupd.fdd and copy the files from the bios update. Lets hope it works
