[flashrom] Problems flashing bios

[Feldi alias aXl]

Hello all,
i have problems flashing my bios with your utility.

i have rented a small root-server in germany
(http://www.hetzner.de/hosting/produkte_rootserver/x2) and wanted to
update the bios.

at the moment the hetzner rescue system is booted. infos:

root at rescue ~ # uname -a
Linux rescue 2.6.39.2 #1 SMP Mon Jul 25 18:36:18 CEST 2011 x86_64 GNU/Linux

its a small debian system.

flashrom is installed via apt:

root at rescue ~ # flashrom --version
flashrom v0.9.2-r1141 on Linux 2.6.39.2 (x86_64), built with libpci
3.1.7, GCC 4.4.5 20100728 (prerelease), little endian
flashrom is free software, get the source code at http://www.flashrom.org

hwinfo says this about my mainboard:

root at rescue ~ # hwinfo --bios | grep "Board Info" -A 10
  Board Info: #2
    Manufacturer: "MICRO-STAR INTERNATIONAL CO., LTD"
    Product: "MS-7094"
    Version: "1.00"
  Chassis Info: #3
    Type: 0x03 (Desktop)
    Bootup State: 0x02 (Unknown)
    Power Supply State: 0x02 (Unknown)
    Thermal State: 0x02 (Unknown)
    Security Status: 0x02 (Unknown)
  Processor Info: #4

so i entered "ms-7094" on the msi page and getted this site:
http://www.msi-computer.de/product/mb/K8T-Neo2-F-V2-0.html#/?div=BIOS

first i backuped the old bios with "flashrom --read bios.bak" and then
tried to write the new bios with "flashrom --write W7094vms.360" ....
then i get this error:

root at rescue ~ # flashrom --write W7094vms.360
flashrom v0.9.2-r1141 on Linux 2.6.39.2 (x86_64), built with libpci
