However I would like to know proper instructions (if possible) to install network drivers without breaking the DSS-V6 system. i cannot find a section "load your own drivers" on the manual.
You didn't find that section, since this is not possbible with Open-E (any version). What type of NIC is that: onboard or seperate? Does it have an off-load engine? If not, you might want to look into one of the PCI-Cards that do have one and that are supported.
